Passive components for Canadian mining equipment cannot be picked from a Walsin Technology (Walsin) datasheet that says mining, because none does. We searched all 28 datasheets we hold, 451 pages, for 15 mining terms and found no hit. Two series name industrial equipment: 913 of 23,601 MLCC part numbers, and 2 of our 1,125 stock lines.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design engineer or buyer in Canada whose board sits in a battery-electric underground vehicle, a charging cabinet or a mine-site enclosure. It is built from our own files: the 24,026-row MLCC export (23,601 distinct part numbers), 28 Walsin PDFs and our stock list of 1,125 lines as at 23 September 2026. Every part number is real. Every news statement names its source, its date and the day we fetched it, 21 October 2026.
What is Canada’s mining sector changing in its equipment right now?
Three funded projects swap diesel machines for battery-electric ones. On 26 June 2026 Natural Resources Canada listed up to 5,000,000 Canadian dollars each for Hudbay’s Lalor mine and for ReThink Mining’s multi-site demonstration, and up to 2,400,000 Canadian dollars for IAMGOLD’s Westwood haul trucks. We read the backgrounder in full on 21 October 2026, and the table paraphrases it.
| Project | What the source says | Source date | What it means for a component buyer | Match / mismatch |
|---|---|---|---|---|
| Hudbay, Lalor mine, Snow Lake, Manitoba | Up to 5,000,000 Canadian dollars to replace diesel mining equipment with battery-electric vehicles and install the charging infrastructure they need | Backgrounder dated 26 June 2026 | Vehicle and charger electronics are a board-level topic for the equipment maker | Match for scope: vehicles and charging. Mismatch for parts: no component, maker or supplier is named |
| IAMGOLD, Westwood mine, Preissac, Quebec | Up to 2,400,000 Canadian dollars for an electric haul truck demonstration, with charging infrastructure | Backgrounder dated 26 June 2026 | Same: power electronics on a large vehicle | Match for scope. Mismatch: the page gives no fleet size or timetable |
| ReThink Mining, several underground mines | Up to 5,000,000 Canadian dollars to demonstrate battery-electric vehicles in real conditions, find barriers to adoption and set deployment practice | Backgrounder dated 26 June 2026 | A demonstration, not a purchasing programme | Mismatch with any demand claim: the page states no volume |
| Glencore, Onaping Depth, Ontario | An order for 23 battery-electric machines from Epiroc: loaders, haulers and drill rigs | Trade report dated 4 July 2022 | Older, and a vehicle maker’s order, not a component signal | Match for vehicle type. Mismatch for date: four years old |
Our view, labelled as ours: none of these sources says a Canadian mine or equipment maker is short of any part, and we name none. Electrified mining fleets are probably built in small series with many variants. That points a buyer at second-source planning and small lots. It is a judgement, not a measurement.
Do Walsin datasheets say anything about mining?
No. We searched the text of all 28 Walsin PDFs we hold, 26 MLCC sheets and 2 chip resistor sheets, 451 pages, for 15 terms: mining, mine, underground, hazardous, explosive, intrinsic, off-highway, off-road, heavy, machinery, truck, agricultural, diesel, tunnel and quarry. Every term returned 0 files. We have not seen this counted anywhere.
Two cautions. The search reads extracted text, so a word set inside a chart image would not be found. And a datasheet that is silent is not a datasheet that forbids: the absence tells you the sheets give you nothing to quote in a mine-approval file. The word that does appear is industrial. It sits in 3 of 28 files, and in one of the three it means an industrial waste vendor in the disposal note, so it names an application in 2 sheets only.
Which two Walsin series name industrial equipment, and how much of the catalogue do they cover?
The MG series and the HT series, and together they are small. MG has 785 distinct part numbers and HT has 128: 913 of 23,601, or 3.9% of the MLCC export. Our stock list holds 0 lines of MG and 2 of HT. We counted distinct part numbers, because the export has 24,026 rows and 425 repeats.
| Walsin series (approval sheet) | What the sheet says about use | Distinct export parts | Stock lines, 23 September 2026 | Match / mismatch for a mining-vehicle board |
|---|---|---|---|---|
| MG (14_MG_Series_High_Reliability) | Non-safety automotive devices and industrial equipment | 785 | 0 | Match on wording. Mismatch on stock: nothing on the shelf |
| HT (15_High_Temperature_HT_150C) | High-temperature measuring instruments, sensor modules and other automotive and industrial sets | 128 | 2 | Match on wording for a hot enclosure. Mismatch on range: 0402 to 1210, 50 and 100 volts only |
| MT (11_Automotive_MT) | Automotive, AEC-Q200 compliant | 2,173 | 0 | Mismatch: names automotive, not industrial; nothing on the shelf |
| SH (19_Soft_Term_SH) | Power supply and lighting industries | 1,488 | 30 | Mismatch on wording; match on soft termination for a board that flexes |
The MG row carries a data defect worth knowing. We counted the tolerance cells: 653 of the 785 MG part numbers print a bare decimal such as -0.1 or -0.05 where other series print plus or minus 10% or 5%, so a filter on tolerance misses most of the series. The wider pattern is in our post on how to read a Walsin MLCC part number.
How does one stocked 0805 line compare across the series a mining board might consider?
Seven other part numbers share its size, capacitance, voltage and tolerance, and two match it on dielectric and nominal thickness. 0805B472K500 is a general purpose 0805, X7R, 4,700 pF, plus or minus 10%, 50 volts, 0.80 mm nominal thickness, and it is on our shelf. We compared all 23,601 distinct export part numbers on size, capacitance, voltage and a 10% tolerance, which some rows write as -0.1, and found 7 others.
| Walsin part | Series as exported | Dielectric, nominal thickness | On shelf 23 Sep 2026 | Your incumbent | Match / mismatch vs 0805B472K500 |
|---|---|---|---|---|---|
0805B472K500 |
General Purpose | X7R, 0.80 mm | Yes | ______ | Reference line |
MT21B472K500 |
Automotive, AEC-Q200 series | X7R, 0.80 mm | No | ______ | Match on dielectric and thickness; the series is the automotive one |
MG21B472K500 |
Automotive, no AEC-Q200 | X7R, 0.80 mm | No | ______ | Match on dielectric and thickness; mismatch: tolerance cell reads -0.1 |
ST21B472K500 |
Automotive soft termination | X7R, 1.25 mm | No | ______ | Mismatch: 0.45 mm taller |
SH21B472K500 |
Soft termination, Ag-poly | X7R, 1.25 mm | No | ______ | Mismatch: 0.45 mm taller |
0805N472K500 |
General Purpose | NPO, 1.25 mm | No | ______ | Mismatch: dielectric and height |
HT21G472K500 |
High Temperature | X8G, 1.25 mm | Yes | ______ | Mismatch: dielectric class and height |
HT21R472K500 |
High Temperature | X8R, 1.25 mm | No | ______ | Mismatch: dielectric and height |
Two lessons. The soft-termination parts are taller, so a footprint or a clearance that was fine for the general purpose part has to be rechecked. And the stocked high-temperature part is a different dielectric class, so capacitance behaviour over temperature and voltage is not the same.
What does the Hong Kong shelf hold for a mining-equipment board?
Mostly general purpose parts, and nothing in an automotive series. As at 23 September 2026, 764 of our 1,125 stock lines resolve to an MLCC export row: 490 general purpose, 149 middle-to-high-voltage, 66 microwave RF, 30 SH soft termination, 22 high Q, 2 HT, 2 large-case, 2 safety and 1 ultra-microwave. None of the 764 is in MT, MG or ST.
The other 361 lines are 254 chip resistors, two inductors, one resistor array and lines with no export row. For the middle-to-high-voltage lines see our post on high-voltage MLCC selection, and the full list is on the ready-stock page. The snapshot is dated and never live. An MG or automotive requirement is a factory order, and we hold no lead time for either.
What will we not tell you about Canadian mining rules?
Anything that is a rule. We hold 0 hazardous-location, intrinsic-safety or mine-approval documents, and the 28 sheets name none. Eighteen document types appear nowhere in the 451 pages, among them REACH, SVHC, PFAS, ISO 9001, IATF 16949, PPAP and IMDS. Walsin spells its test sheets out; the compliance paperwork a mine operator asks for is not in what we hold, and it is on our request list.
Venatech holds neither ISO 9001 nor IATF 16949. We state no Canadian customs content, duty or approval requirement, and we hold no office or stock in Canada: our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. Confirm every approval point with your compliance team.
How can Venatech help a Canadian mining equipment team cross a part?
Four ways, all checkable, and one honest limit. The free cross-reference tool decodes 18 manufacturers’ part numbers across 800,000+ crossable parts; you paste an incumbent number and it lists Walsin candidates with match and mismatch fields, as the 0805 table above does by hand.
- VenaMatch cross-reference. Paste up to 500 part numbers or an Excel or CSV file. Differences are stated, not hidden.
- BOM check. Upload a bill of materials at /bom/ and check it against the same cross-reference engine.
- Ready stock. The Hong Kong list is a snapshot dated 23 September 2026, not live-synced.
- Service. Walsin is the only line we are authorised for. We are Hong Kong based, work in small lots and will help you cross a part; request a quote through the site. Lot and date-code traceability and a certificate of conformity per shipment are available on request.
Worked example from our own export: paste 0805B472K500 and the 7 other part numbers above are the candidates, with a 0.45 mm nominal height difference on five of them. Qualification stays with you. Our MLCC range lists the series, and we send any of the 28 datasheets on request.

The short version
A Canadian mining equipment team will find no Walsin sentence about mining. The only sheets that name industrial equipment, MG and HT, cover 913 of 23,601 MLCC part numbers, and our shelf holds 2 lines of them and none in an automotive series. Choose by the electrical fields and the height, not by the application line.
Send us one MLCC line from a battery-electric vehicle BOM and we will return the Walsin candidates with the differences stated. If your approval file needs a datasheet sentence that says underground, which supplier has ever printed one?
Frequently asked questions
What is Canada funding in mining equipment?
Natural Resources Canada’s backgrounder of 26 June 2026 lists up to 5,000,000 Canadian dollars each for Hudbay’s Lalor mine and for ReThink Mining, and up to 2,400,000 Canadian dollars for IAMGOLD’s Westwood mine. All three involve battery-electric vehicles. The page names no component or supplier. We fetched it on 21 October 2026.
Do Walsin datasheets name mining or underground use?
No. We searched the text of all 28 datasheets we hold, 451 pages, for 15 terms including mining, underground, hazardous and explosive. Every term returned 0 files. A buyer who needs a datasheet statement for a mine approval file will not find one in the documents we hold.
Which Walsin MLCC series name industrial equipment?
Two. The MG sheet names non-safety automotive devices and industrial equipment, and the HT sheet names other automotive and industrial sets that must withstand high temperatures. Together they hold 913 of 23,601 distinct MLCC part numbers, 3.9 percent, and 2 of our 1,125 stock lines.
Do you hold automotive-series MLCC in Hong Kong stock?
Not as at 23 September 2026. Of 764 stock lines that resolve to an MLCC export row, none is in the MT, MG or ST series. The MT sheet says the series meets AEC-Q200 requirements; we say compliant, never certified. Ask for the qualification report on the exact part number. Stock moves, so ask for the current position.
Which Walsin MLCC series reaches 150 degrees Celsius?
The HT series. Its sheet prints an operating range of minus 55 to plus 150 degrees Celsius, and the export holds 128 part numbers, 102 X8G and 26 X8R, from 0402 to 1210 at 50 and 100 volts. We stock 2 lines. Confirm temperature behaviour against the datasheet for the exact part.
Do you give Canadian mine-approval or hazardous-location advice?
No. We hold no hazardous-location, intrinsic-safety or mine-approval documents, and no Canadian customs content. We supply parts, lot and date-code traceability and, on request, a certificate of conformity per shipment. Confirm every approval point with your compliance team.
