Industrial precision resistors for Taiwan at 25 ppm or better come from one series: the Walsin Technology (Walsin) export lists 3,087 of them among 52,027 high-precision thick film parts, and only in 0603, 0805 and 1206. A 10 kilohm, plus or minus 0.1 percent brief returns 3 parts, and no 25 ppm part is on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this from the Walsin chip resistor export (234,815 rows, 234,401 distinct part numbers) and our stock list as at 23 September 2026. It is for a design or sourcing engineer at a Taiwanese maker of industrial controls, machinery or measurement equipment, in Hsinchu or elsewhere, who is crossing a precision resistor. Every part number is real and every count is ours, re-measured on 10 November 2026. The market statement names its source and the day we fetched it.
What did Hsinchu Science Park report for the first half of 2026, and why does a component buyer care?
It reported record revenue and strong growth in precision machinery. According to TechNews on 29 September 2026, Hsinchu Science Park’s operating revenue for the first half of 2026 was about 1,119.5 billion New Taiwan dollars, up 36.03 percent and its first half-year above 1 trillion, with precision machinery up 35.98 percent, integrated circuits up 31.02 percent and employment at a record 181,431.
The report gives exports up 65.58 percent and computers and peripherals up 113.34 percent, driven by AI servers. Those are the report’s figures, not ours. The conclusion we draw is ours: a park whose precision machinery sector grows at that rate builds instruments and drives that carry precision resistors in feedback and reference circuits. We have no relationship with any Hsinchu company, and we say nothing about what any of them buys.
Which Walsin resistors match a 10 kilohm, plus or minus 0.1 percent, 25 ppm, 0805 brief, and what differs?
One matches exactly, and two more differ only in size. We parsed the 52,027 high-precision thick film rows and found 29 at 10 kilohm and plus or minus 0.1 percent: 3 hold 25 ppm per degree Celsius or better, 8 hold 50 ppm or better, 16 hold 100 ppm, and 2 are 200 ppm; the one in 0805 at 1/8 W is WF08J1002BTL.
Our brief is ours. The reader’s incumbent goes in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
WF08J1002BTL |
High Precision TC25, 0805, 10 kilohm, plus or minus 0.1%, 1/8 W, 25 ppm or better | No | Match on size, value, tolerance, power and coefficient | |
WF06J1002BTL |
High Precision TC25, 0603, 10 kilohm, plus or minus 0.1%, 1/10 W, 25 ppm | No | Match on the electrical fields; mismatch in case size and power | |
WF12J1002BTL |
High Precision TC25, 1206, 10 kilohm, plus or minus 0.1%, 1/4 W, 25 ppm | No | Match on the electrical fields; mismatch in case size and power | |
WF08K1002BTL |
High Precision TC50, 0805, 10 kilohm, plus or minus 0.1%, 1/8 W, 50 ppm | No | Mismatch: coefficient is 50 ppm, looser | |
WF08H1002BTL |
High Precision TC100, 0805, 10 kilohm, plus or minus 0.1%, 1/8 W, 100 ppm | No | Mismatch: coefficient is 100 ppm, four times looser | |
WF12H1202BTL |
High Precision TC100, 1206, 12 kilohm, plus or minus 0.1%, 1/4 W, 100 ppm | Yes | Mismatch: 12 kilohm, 1206 and 100 ppm; the nearest shelf part |
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 thin film against thick film chip resistors explains when a thick film part is not enough, and tolerance, TCR and dielectric codes decoded covers the notation.
How rare is a 25 ppm Walsin thick film resistor?
About 1 in 17 of the high-precision rows. We counted the series: TC25 holds 3,087 of 52,027 parts (5.9 percent), spread evenly over plus or minus 0.1, 0.25 and 0.5 percent and over 0603, 0805 and 1206, with exactly 343 resistance values in each of those 9 cells; no TC25 part exists in 0402, 0201, 1210, 2010 or 2512, or at plus or minus 1 percent.
The regularity is the useful part: 343 values per cell means the series is a table, not a patchwork, so a missing value in one size is missing in all three. Across all high-precision rows, tolerance takes four values only (0.1, 0.25, 0.5 and 1 percent) and the file named for plus or minus 0.05 percent returns zero rows, so a tighter tolerance than 0.1 percent is not in this export. We have not seen this counted anywhere. Paste your value into the cross-reference tool and read the coefficient before the footprint.
What does the Hong Kong shelf hold in high-precision resistors?
Five parts, none at 25 ppm. Of the 52,027 high-precision part numbers, 5 are on our stock list as at 23 September 2026: three at plus or minus 0.1 percent (WF12H1202BTL, WF12H5762BTL and WF08H8203BTL) and two at plus or minus 0.5 percent in 0402, all TC100 at 100 ppm.
None is in the TC25 series. The ready stock list is a dated snapshot, never live-synced, and the chip resistor range lists the families. If your brief needs 25 ppm, ask for a to-order enquiry through the site; we will say plainly what we hold and what we do not.
What will we not tell you about industrial precision boards?
Anything about your measurement chain, your drift budget or your calibration. Of the 28 Walsin datasheets we hold, 26 cover MLCC and 2 cover chip resistors (the MR and WR families), so for the 52,027 high-precision rows every count here is catalogue coverage, not suitability.
A coefficient of 25 ppm per degree Celsius is a catalogue limit, not a drift guarantee for your circuit, and the datasheet for the series is not among the ones we hold. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Taiwan; 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.
How can Venatech help a Taiwanese industrial electronics maker?
How Venatech helps starts with a free paste box. The cross-reference tool (VenaMatch) decodes 18 manufacturers’ part numbers, covers 800,000+ crossable parts, 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, plus or minus 0.1 percent, 0805, 25 ppm brief returned 1 exact part among 29 at the value, none stocked, and the nearest shelf part is a 12 kilohm 1206 at 100 ppm. 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.
The short version
For a Taiwanese industrial board, 25 ppm is a series question: 3,087 TC25 parts of 52,027, only in 0603, 0805 and 1206, 343 values per cell, 3 parts at 10 kilohm and plus or minus 0.1 percent, no tolerance tighter than 0.1 percent, and none on the shelf. State the coefficient, not just the value.
Send us one precision resistor line from your BOM, with the value, tolerance, coefficient and size you can accept, and we will return the Walsin parts with every difference stated. If your incumbent prints only plus or minus 0.1 percent, do you know whether it is 25, 50 or 100 ppm?

Frequently asked questions
What did TechNews report about Hsinchu Science Park in September 2026?
On 29 September 2026 it reported first-half 2026 operating revenue of about 1,119.5 billion New Taiwan dollars, up 36.03 percent, with precision machinery up 35.98 percent and employment of 181,431. These are the report’s figures, not ours.
How many Walsin high-precision resistors hold 25 ppm or better?
3,087 of 52,027 part numbers, all in the TC25 series, and only in 0603, 0805 and 1206 at plus or minus 0.1, 0.25 and 0.5 percent. None is on our shelf.
Which Walsin resistor matches 10 kilohm, plus or minus 0.1 percent, 25 ppm, in 0805?
WF08J1002BTL, rated 1/8 W. WF06J1002BTL (0603) and WF12J1002BTL (1206) match the electrical fields but differ in case size and power. Confirm against the datasheet and qualify in your circuit.
Does Walsin offer a thick film resistor tighter than plus or minus 0.1 percent?
Not in this export. The high-precision rows carry four tolerances only (0.1, 0.25, 0.5 and 1 percent), and the file named for 0.05 percent returns zero rows. Walsin’s thin film range is a separate export we have not searched for this brief.
Which high-precision Walsin resistors are on the Hong Kong shelf?
As at 23 September 2026, five, all 100 ppm: WF12H1202BTL, WF12H5762BTL and WF08H8203BTL at plus or minus 0.1 percent, and WF04H1202DTL and WF04H3302DTL at plus or minus 0.5 percent. The snapshot is dated, not live.
Is a 25 ppm rating a guarantee of drift in my circuit?
No. It is a catalogue limit on temperature coefficient, not a system drift figure. Self-heating, board stress and ageing also matter, so qualify in your own circuit.
Do you hold stock or an office in Taiwan?
No. We hold no office, entity or stock in Taiwan; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen. We hold no ISO 9001 or IATF 16949 certificate and give no legal, customs or conformity advice.
