A feasibility study published on 9 November 2026 sets out a 67 MW data centre in the UK powered by twelve on-site gas engines. Voltage sensing on generator-fed boards usually runs through a high voltage chip resistor divider. Walsin lists 20,244 such part numbers, and none of the export’s 10 columns states a voltage rating.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a UK switchgear, metering, generator-control, UPS or data centre power company. Walsin Technology (Walsin) is the only line we are authorised for. The Walsin side is our own export of the Thick Film High Voltage Chip Resistor series, 14 files of which 4 hold rows, re-measured on 11 November 2026. Every part number below is real and appears in that export.
What is the West Newton gas-to-data-centre study in the UK?
A concept, not a commitment. Share Talk reported on 9 November 2026 that Reabold Resources completed a Stage 1 feasibility study for a data centre at its West Newton project with about 67 MW of IT capacity in ten 6.6 MW halls, powered by twelve 15 MW gas engines, ten duty and two standby, with first power targeted for the second half of 2030.
The report, which we read on 11 November 2026, puts concept capital expenditure at about 1.1 billion pounds, gives roughly 130 MW of available output against about 103 MW of calculated peak demand, and says the study was carried out by the consultancy Kent with PMO Hive Group. It stresses that completing the study is not a commitment to build. These are the company’s figures as reported, not ours, and we say nothing about who would supply the project.
Why does on-site generation put a high voltage chip resistor on the monitoring board?
Because every generator, transfer switch and power meter has to measure line voltage. Low-voltage measurement on a 400 V three-phase system commonly divides the line voltage down through a chain of high-value resistors in series, so each resistor in the chain must hold its share of the voltage, not just dissipate its share of the power.
That is general engineering practice, and the exact chain is your design: how many resistors, at what value, with what creepage and what surge test. A site that runs on its own engines rather than the grid makes voltage and frequency monitoring part of normal operation, not a backup function. The resistor’s working voltage, overload voltage and pulse rating are what decide how many you need in series.
What does Walsin’s export say about high voltage chip resistors?
Everything except the voltage. We read all 20,244 rows (20,244 distinct part numbers) of Walsin’s Thick Film High Voltage Chip Resistor export: 10 columns, covering part number, series group, series, size, resistance, tolerance, TCR, rated power, packaging and termination, and none of them is a working, overload or withstanding voltage.
The series spans five sizes, 0603 (3,924 part numbers), 0805 (3,966), 1206, 2010 and 2512 (4,118 each), from 47 ohm to 100 megohm; the 0603 stops at 22 megohm and the 0805 at 51 megohm. We counted 11,497 parts at 1 percent, 3,045 at 0.5 percent, 3,045 at 2 percent and 2,657 at 5 percent. TCR reads plus or minus 100 ppm or better on 17,033 rows, 200 ppm on 3,043, and minus 200 to plus 500 ppm on 168.
The series is called high voltage, and the export cannot tell you how high. We hold no datasheet for this series; the only two Walsin resistor datasheets we hold are for the MR automotive and WR general purpose lines. That absence is the finding.
How many Walsin parts sit at 1 megohm in 1206, and how do they differ?
Twelve, in three prefixes. We counted 12 distinct Walsin high voltage part numbers at 1 megohm in 1206, all rated 1/4 W with a lead-free tin termination: 6 begin WK12V, 2 begin WF12V and 4 begin WF12N, at tolerances of 0.5, 1, 2 and 5 percent.
| Part number | Prefix | Tolerance | TCR in export | Match / mismatch against a 1 megohm, 1 percent, 100 ppm, 1206 brief | Your incumbent |
|---|---|---|---|---|---|
WK12V1004FTL |
WK12V | 1% | 100 ppm or better | Match on value, tolerance, TCR and size; voltage unconfirmed | |
WF12V1004FTL |
WF12V | 1% | 100 ppm or better | Match on listed fields; voltage unconfirmed | |
WF12N1004FTL |
WF12N | 1% | 100 ppm or better | Match on listed fields; voltage unconfirmed | |
WK12V1004DTL |
WK12V | 0.5% | 100 ppm or better | Match; tighter tolerance | |
WK12V105 JTL |
WK12V | 5% | 100 ppm or better | Mismatch on tolerance | |
WF12V105 JTL |
WF12V | 5% | 200 ppm or better | Mismatch on tolerance and TCR |
Three parts match a 1 percent, 100 ppm brief on every field the export carries, and we cannot tell you which of them suits a 400 V divider, because the field that decides it is not in the file. Note also that the 5 percent part numbers carry an embedded space, which breaks a paste into many BOM tools; see why Walsin part numbers do not paste into your BOM.
What does the Hong Kong shelf hold in high voltage chip resistors?
Nothing in this series. We read the stock list as at 23 September 2026: 254 of its 1,125 part numbers are chip resistors, and 0 of them is in Walsin’s high voltage series.
A high voltage divider resistor from Walsin is a request through the site, not a shelf pick. The ready stock list is a dated snapshot, never live-synced, and we make no lead-time or availability promise. For how power rating scales with case size, see chip resistor power rating by case size.
How can Venatech help a UK power-monitoring or switchgear team?
How Venatech helps starts with the free cross-reference tool, VenaMatch, which decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts. Paste up to 500 part numbers or an Excel or CSV file, and each Walsin candidate comes back with every field marked match or mismatch, including the fields it cannot confirm.
