Payment terminal electronics for Nigeria hit a quiet limit at 0201: of 11,985 Walsin Technology (Walsin) general purpose 0201 resistors at plus or minus 1 percent, only 491 publish a 100 ppm temperature coefficient, all in the Automotive series. The four 0201 lines on our shelf publish 200 ppm.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this from the Walsin chip resistor exports (234,401 distinct part numbers, 14,535 of them general purpose 0201) and our stock list as at 23 September 2026. It is for a design or sourcing engineer at a Nigerian maker or assembler of POS, mobile-money or payment terminals who is crossing a small divider or pull-up resistor. Every part number is real and every count is ours. The market statement names its source and the day we fetched it, 2 November 2026.
What did Nairametrics report on Nigerian POS and mobile payment volumes, and why does it matter to a component buyer?
It reported a shift in how Nigerians pay. According to Nairametrics on 20 October 2026, citing Central Bank of Nigeria first-quarter 2026 figures quoted by a fintech chief executive, mobile payment volumes grew about 29 percent year on year, POS transaction volumes fell about 20 percent and ATM volumes rose about 7 percent.
Those are the article’s figures, as quoted, not ours. The conclusion we draw is ours: a terminal maker facing a changing mix needs part numbers that survive a redesign, and a resistor choice made on nominal value alone is the one that gets redone. We have no relationship with any Nigerian bank, fintech or terminal maker, and we say nothing about what any of them buys.
Which Walsin 0201 resistors cross a 10 kilohm, plus or minus 1 percent, 100 ppm brief, and what differs?
Only one is a clean match on the numbers. We parsed all 14,535 general purpose 0201 rows in the Walsin export; 11,985 are plus or minus 1 percent, and of those 9,328 publish 200 ppm and 491 publish 100 ppm, every one of the 491 in the Automotive series. At 10 kilohm that leaves 15 part numbers at plus or minus 1 percent, and exactly 1 of them, MR02X1002FAL, publishes 100 ppm.
The reader’s incumbent goes in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
MR02X1002FAL |
Thick Film General Purpose (Automotive series), 0201, 10 kilohm, plus or minus 1%, TCR 100 ppm, 15 kpcs 7-inch reel | No | Match on size, value, tolerance and TCR; mismatch in series label | |
WR02X1002FAL |
General Purpose, 0201, 10 kilohm, plus or minus 1%, TCR 200 ppm, 15 kpcs 7-inch reel | Yes | Mismatch: TCR is 200 ppm, not 100; the nearest shelf part | |
WR02X1002FTL |
General Purpose, 0201, 10 kilohm, plus or minus 1%, TCR 200 ppm, 10 kpcs 7-inch reel | No | Mismatch: TCR 200 ppm; different reel quantity | |
WR02X1002FAR |
Series named LF 100ppm, 0201, 10 kilohm, plus or minus 1%, TCR column reads 200 ppm | No | Mismatch: the series name says 100 ppm, the TCR field says 200; read the datasheet | |
WR02X1002FALV |
Anti-sulfuration, Automotive-labelled, 0201, 10 kilohm, plus or minus 1%, TCR 200 ppm | No | Mismatch: TCR 200 ppm; different series |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit. Our post on tolerance, TCR and dielectric codes decoded explains the fields, and how Walsin chip resistor part numbers work shows the suffix letters.
Why do the LF 100ppm 0201 parts publish no 100 ppm value?
Because the TCR column and the series name disagree at this size. We counted the 1,938 0201 parts in the series named LF 100ppm: none publishes 100 ppm, 1,108 publish 200 ppm and 276 publish 300 ppm; at 0402 to 1206 the same series publishes 100 ppm on 1,259 parts per size.
A buyer who filters on the series name for a 0201 tight-TCR line therefore finds a series that does not deliver the number at that size. We have not seen this counted at 0201 anywhere. The fix is to filter on the TCR field and then read the datasheet, which is what the cross-reference tool compares.
What does the Hong Kong shelf hold in 0201 general purpose resistors?
Four lines, all at 200 ppm. Of the 14,535 general purpose 0201 part numbers, 4 are on our stock list as at 23 September 2026: WR02X2400FAL (240 ohm), WR02X4700FAL (470 ohm), WR02X1241FAL (1.24 kilohm) and WR02X1002FAL (10 kilohm), each plus or minus 1 percent and 200 ppm.
Notice that the 10 kilohm line prints its value as 10000Ω, so a search for 10K finds nothing in the export. The ready stock list is a dated snapshot, never live-synced, and the chip resistor range lists the families.
What will we not tell you about payment terminals?
Anything about your approvals, your certification scheme or your fraud controls. Of the 28 Walsin datasheets we hold, 2 cover chip resistors, and neither names a payment product, so every count here is catalogue coverage, not suitability.
We make no claim that any part suits a POS or mobile-money terminal or meets any payment-industry scheme. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Nigeria; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you.
Why do buyers in Nigeria choose Venatech?
Because we tell you what the number really is. Venatech Limited is an authorised Walsin Technology distributor in Hong Kong, and the Walsin general purpose 0201 range alone is 14,535 part numbers across 848 resistance values and four series.
A Nigerian buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and flags the 200 ppm before the board is built. Our VenaMatch tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and every candidate comes back with each field marked match or mismatch. We would rather show you the gap now than find it with you at qualification.
How can Venatech help a Nigerian terminal maker?
How Venatech helps starts with a free paste box. The cross-reference tool accepts up to 500 part numbers or an Excel or CSV file and shows Walsin candidates with each field marked match or mismatch. Load a whole BOM for a check. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 10 kilohm 0201 brief at plus or minus 1 percent and 100 ppm returned 1 clean part in a different series label, and the shelf holds the 200 ppm line. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site. We hold 28 Walsin datasheets, 451 pages, and send them on request.
The short version
For a Nigerian terminal maker, a 0201 resistor brief hides a TCR split: 491 of 11,985 plus or minus 1 percent parts publish 100 ppm, all Automotive series, and the four shelf lines publish 200 ppm. A series named LF 100ppm publishes none at 0201. Read the field, not the name.
Send us one 0201 resistor line from your BOM, with the TCR you can accept, and we will return the Walsin parts with every difference stated. If your incumbent says 100 ppm in its series name, does its TCR field say it too?

Frequently asked questions
What did the Central Bank of Nigeria figures show for POS in Q1 2026?
As quoted by Nairametrics on 20 October 2026, POS transaction volumes declined about 20 percent, mobile payment volumes grew about 29 percent and ATM volumes rose about 7 percent. These are second-hand figures quoted in the article, not ours.
How many Walsin 0201 general purpose resistors publish 100 ppm at plus or minus 1 percent?
491 of 11,985, all in the Thick Film General Purpose Automotive series. 9,328 publish 200 ppm. Confirm each against its datasheet before design-in, and ask for the qualification report for the exact part number if you need it.
Which Walsin 0201 part crosses a 10 kilohm, plus or minus 1 percent, 100 ppm brief?
MR02X1002FAL matches on size, value, tolerance and TCR but sits in the Automotive series. The other 14 parts at 10 kilohm and plus or minus 1 percent publish 200 ppm. Confirm against both datasheets and qualify in your own circuit.
Why does the LF 100ppm series not give 100 ppm at 0201?
In the export, none of its 1,938 0201 parts publishes 100 ppm; 1,108 publish 200 ppm. At 0402 to 1206 it publishes 100 ppm on 1,259 parts per size. Filter on the TCR field and check the datasheet, not the series name.
Which Walsin 0201 resistors are on the Hong Kong shelf?
Four, as at 23 September 2026: WR02X2400FAL, WR02X4700FAL, WR02X1241FAL and WR02X1002FAL, each plus or minus 1 percent and 200 ppm. The snapshot is dated, not live, so ask us through the site for current availability.
