5G Infrastructure Passive Components for Canada: 7 of 28 Walsin Datasheets Contain 5G and None Means a Network, 3 Name Base Stations, and the Shelf Holds 67 Microwave Lines

5G infrastructure passive components for Canada cannot be picked from a Walsin Technology (Walsin) datasheet that says 5G, because none does. We searched all 28 datasheets we hold, 451 pages. Seven contain the characters 5G, and none means a network. Three name base stations. Our shelf holds 67 lines in the microwave series.


Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design engineer or buyer in Canada who builds or services radio equipment: small cells, tower-top units, backhaul or test gear. 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. We covered cold-climate telecom cabinets in an earlier Canada post; this one is about the radio side.

What is Canada changing in 5G spectrum and towers right now?

Two things: a millimetre-wave auction and a tower-approval reform. On 19 May 2026 the federal innovation department announced rules for an auction planned for 2027 that offers 4.8 GHz of spectrum in the 26 GHz and 38 GHz bands, and proposed a standard digital process for tower approvals. We read the release in full on 21 October 2026, and the table paraphrases it.

Point What the source says Source date What it means for a component buyer Match / mismatch
Millimetre-wave auction rules 4.8 GHz in the 26 GHz and 38 GHz bands to be auctioned in 2027, with a cap on how much any one bidder can hold and small licence areas; a further 850 MHz in the 26 GHz band to follow through a non-competitive process Release dated 19 May 2026 Context only: the release names no component, supplier or equipment maker Mismatch with any demand claim: no volume or build plan is stated
Tower siting proposal A standardised digital approval process with a public online portal and clearer timelines, open to comment Release dated 19 May 2026 Process reform for tower owners; no bill of materials follows from it Mismatch: a proposal, not a rule in force
3800 MHz auction 250 MHz in the 3650 to 3900 MHz range; 20 operators won 4,099 of 4,300 licences Trade report dated 5 December 2023 The mid-band spectrum already awarded; the 2027 auction is the next step Match for scope: Canadian 5G spectrum. Mismatch for date: nearly three years old

Our view, labelled as ours: none of these sources says a Canadian operator or equipment maker is short of any part, and we name none. Whether a radio design needs a given capacitor is for the design owner. If the point is licensing or approvals, confirm with your compliance team.

Do Walsin datasheets mention 5G?

No. We searched the text of all 28 Walsin PDFs we hold, 26 MLCC sheets and 2 chip resistor sheets, 451 pages, for the characters 5G. Seven files match. In six it is the vibration test level of 5 g’s, and in the seventh, the full catalogue, it is the end of 8.5GHz. None names a network generation. We have not seen this counted anywhere.

A bare text search would mislead here: it hands you seven files that look like proof of 5G coverage and are nothing of the kind, which is why we read every hit. What the sheets do say is narrower. Three of them list base stations among their telecommunication uses, and one adds small cells. Walsin’s own RF module parts (filters, baluns, couplers, multiplexers) are a separate matter: 457 parts with no datasheet on file, covered in our post on RF components above 3 GHz.

Which Walsin sheets name base stations, and can the cross-reference tool offer them?

Three sheets name them, and one of the three cannot be crossed. The Microwave RF, High Reliability RH and Narrow Tolerance UF sheets list base stations; the RH sheet also lists small cells and has 0 rows in the export. The two sheets that can be crossed cover 3,900 distinct part numbers, 16.5% of 23,601.

Walsin sheet What it lists under telecommunication Distinct export parts Stock lines, 23 September 2026 Match / mismatch for a base-station board
06_Microwave_RF Mobile phone, WLAN, base station 3,615 66 Match on wording. Sizes 0201, 0402, 0603, 0805, 0505, 1111 and 01R5
07_Microwave_High_Reliability_RH Mobile phone, WLAN, base station, small cell 0 0 Mismatch: datasheet on file, no export rows, so the tool cannot offer an RH part
08_Microwave_Narrow_Tolerance_UF Mobile phone, WLAN, base station 285 1 Match on wording. Sizes 0201 and 0402 only
10_High_Q_Low_ESR_HH Mobile phone, WLAN; RF module, tuners 1,706 22 Mismatch on wording: no base station
01_General_Purpose Generic telecommunication 8,330 490 Mismatch: no base station named

The RH gap is the commercial one. Its sheet is the only one that names small cells, and we cannot cite a single RH part number because the parametric export holds none. The rows are on our request list, and until they arrive the honest answer to an RH requirement is that we have the sheet and not the data.

Which stocked microwave line has a tighter-tolerance twin?

Twenty-three of the 66. We matched every stocked RF-series line to the UF series on size, dielectric and capacitance: 23 have at least one UF part, 13 at 0402 and 10 at 0201. Only 8 of the 23 also share tolerance and voltage; the other 15 differ on one or both. Just 1 UF part is itself on the shelf.

The reference is RF03N3R9C500, an 0201 NPO 3.9 pF part at plus or minus 0.25 pF and 50 volts, and it is on our shelf.

Walsin part Series as exported Size, value, tolerance, voltage On shelf 23 Sep 2026 Your incumbent Match / mismatch vs RF03N3R9C500
RF03N3R9C500 Microwave RF 0201, 3.9 pF, plus or minus 0.25 pF, 50 V Yes ______ Reference line
RF03N3R9A500 Microwave RF 0201, 3.9 pF, plus or minus 0.05 pF, 50 V No ______ Match on size, value and voltage; mismatch: tolerance five times tighter
UF03N3R9B101 Ultra Microwave UF 0201, 3.9 pF, plus or minus 0.1 pF, 100 V Yes ______ Mismatch: series, tolerance and voltage
UF03N3R9A500 Ultra Microwave UF 0201, 3.9 pF, plus or minus 0.05 pF, 50 V No ______ Match on size, value and voltage; mismatch: series and tolerance
RF15N0R8A500 Microwave RF 0402, 0.8 pF, plus or minus 0.05 pF, 50 V Yes ______ Second reference
UF15N0R8A500 Ultra Microwave UF 0402, 0.8 pF, plus or minus 0.05 pF, 50 V No ______ Match on all five fields; mismatch: series, so a different sheet governs it
UF15N0R8P500 Ultra Microwave UF 0402, 0.8 pF, plus or minus 0.02 pF, 50 V No ______ Mismatch: tolerance 2.5 times tighter than the second reference

A defect to know before you filter. In the UF export 12 of 285 rows write the tolerance with the plus-minus symbol and 273 write it as +- in plain text, so a text filter for the 0.03 pF grade returns 19 of the 29 parts and misses 10. The same trap runs through the corpus; our post on how to cross-reference an MLCC sets out the method.

Do the Walsin microwave sheets say anything about 26 GHz or 38 GHz?

No. We searched all 28 files for 26 GHz, 28 GHz, 38 GHz, mmWave and millimetre and found 0. The only GHz figure in the four microwave sheets is the 1 GHz test frequency, 1 plus or minus 0.1 GHz, used for the Q and ESR limits. The full catalogue adds one self-resonance chart.

That does not mean a part cannot work at those frequencies. It means we hold no Walsin statement to hand you. A 26 GHz or 38 GHz design needs a vendor-supplied model or measurement at the operating point, and the right first step is to ask Walsin through us for exactly that, naming the part number. Our shelf is 67 lines of 0201 to 0805 NPO and X8G parts, 26 at 0201, 23 at 0402, 12 at 0603 and 5 at 0805, plus one UF line, and the ready-stock page shows the current list. It is a dated snapshot, never live.

What will we not tell you about Canadian telecom approvals?

Anything that is a rule. We state no spectrum-licence, equipment-certification, tower-siting or customs requirement, we hold no Canadian regulatory documents, and 18 document types appear nowhere in the 451 pages we hold, including REACH, SVHC, PFAS, ISO 9001, IATF 16949, PPAP and IMDS. All of those are on our request list, not on our desk.

Venatech holds neither ISO 9001 nor IATF 16949. We have no office or stock in Canada: our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. Your compliance team owns every approval point.

How can Venatech help a Canadian telecom hardware team cross a part?

Four ways, 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 table above does by hand for 7 microwave parts.

  • 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. We send any of the 28 datasheets on request.

Worked example from our own export: paste RF15N0R8A500 and the export shows 5 UF parts at the same size and value, one of them on all five fields, so the question for your design is which sheet governs. Our MLCC range lists the series. The limit: for RH, and for any RF module part, we hold no rows or no datasheet, and we say so.

Which sources back the statements above?

Fetched 21 October 2026. The spectrum and tower statements come from these pages, paraphrased; the part data comes from our own Walsin exports, approval sheets and stock list.

The short version

For Canadian 5G radio hardware the Walsin documents are quieter than the headlines. 7 of 28 files contain 5G and none means a network, 3 name base stations, 0 mention 26 or 38 GHz, and the one sheet that names small cells has no rows to cross. The usable core is the 3,900 microwave part numbers and the 67 lines on our shelf.

Send us one microwave MLCC line from your radio BOM and we will return the Walsin candidates with the differences stated. If your design review wants a datasheet sentence about 5G, whose datasheet has ever printed one for a capacitor?


Frequently asked questions

What is Canada changing in 5G spectrum and towers?

On 19 May 2026 the federal innovation department announced rules for a millimetre-wave auction planned for 2027, offering 4.8 GHz in the 26 GHz and 38 GHz bands, and proposed a standard digital process for tower approvals. The release names no component. We fetched it on 21 October 2026.

Do Walsin datasheets mention 5G?

No. We searched all 28 datasheets we hold, 451 pages, for the characters 5G. Seven files match, but six are the 5 g vibration test level and one is the end of 8.5GHz. None names a network generation. Three sheets name base stations and one adds small cells.

Which Walsin MLCC sheets name base stations?

The Microwave RF sheet, the High Reliability RH sheet and the Narrow Tolerance UF sheet. The RH sheet also names small cells, but the export holds 0 RH rows, so the cross-reference tool cannot offer an RH part. The RF and UF series hold 3,900 distinct part numbers between them.

Do you hold microwave MLCC in Hong Kong stock?

Yes, as at 23 September 2026. Our stock list resolves to 66 lines in the Microwave RF series and 1 in the UF series, from 0201 to 0805. 23 of the 66 have a UF part at the same size, dielectric and capacitance. Stock moves, so ask for the current position and pack quantity.

Do Walsin sheets cover 26 GHz or 38 GHz?

No. We searched all 28 files for 26 GHz, 28 GHz, 38 GHz, mmWave and millimetre and found none. The microwave sheets quote Q and ESR at a test frequency of 1 GHz. For a millimetre-wave design, ask for a part-specific measurement or model and qualify in your own circuit.

Do you give Canadian licensing or equipment-approval advice?

No. We state no spectrum-licence, equipment-certification, tower-siting or customs requirement, and we hold no Canadian regulatory documents. 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.
