For automotive electronics in Slovakia, the Walsin Technology (Walsin) high-voltage thick-film resistor list has no 0.5 percent grade in its automotive series: 3,045 general rows carry it, and 3,045 automotive rows carry 2 percent instead. A divider that needs 0.5 percent has no automotive-series match. None of the 20,244 rows is on the shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a Slovak automotive supplier, in Kosice or elsewhere, who divides or senses a high-voltage rail with thick-film chip resistors. It comes from the four Walsin high-voltage resistor files (20,244 rows, 20,244 distinct part numbers) and our stock list as at 23 September 2026. Every part number is real. Market facts name their source and the day we fetched it, 10 November 2026.
How many cars did Slovakia build in 2025, and what is happening in Kosice?
About 1.07 million, and a new plant is still to start. According to a TASR report of 13 January 2026 citing the Slovak automotive association ZAP, Slovakia produced about 1.07 million cars in 2025 on preliminary figures, or 196 vehicles per 1,000 inhabitants, up from roughly one million in 2024.
In Kosice, Reuters reported on 4 July 2025 (carried by Gulf Daily News) that Volvo Cars had moved large-scale production at its Kosice plant, still under construction, to early 2027, with a planned capacity of about 250,000 cars a year, and that Polestar intended to build its Polestar 7 there from 2028. We found no later dated update in today’s search, so read those as plans. We hold no data on what any carmaker or supplier in Slovakia buys.
Which Walsin 0805 1 megohm resistors cross an automotive, plus or minus 1 percent brief?
Eight parts share the value; one matches. We filtered the high-voltage files to 0805, 1 megohm, 1/8 W and found 8 part numbers in the non-UL lists, 5 of them at 0.5 to 2 percent and 3 at 5 percent; exactly 1, WK08V1004FTLJ, matches an automotive-series, plus or minus 1 percent brief on every export field.
The table shows the five at 0.5 to 2 percent. Put your incumbent in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
WK08V1004FTLJ |
High-voltage thick film, automotive series, 0805, 1 megohm, plus or minus 1 percent, 100 ppm, 1/8 W | No | Match on series, size, value, tolerance and power | |
WK08V1004GTLJ |
High-voltage thick film, automotive series, 0805, 1 megohm, plus or minus 2 percent, 1/8 W | No | Mismatch: tolerance is plus or minus 2 percent, wider | |
WK08V1004FTL |
High-voltage thick film, general series, 0805, 1 megohm, plus or minus 1 percent, 1/8 W | No | Mismatch: general series, not the automotive series | |
WK08V1004DTL |
High-voltage thick film, general series, 0805, 1 megohm, plus or minus 0.5 percent, 1/8 W | No | Mismatch: general series and tighter tolerance, plus or minus 0.5 percent | |
WF08V1004FTL |
High-voltage thick film, general series, WF prefix, 0805, 1 megohm, plus or minus 1 percent, 1/8 W | No | Mismatch: general series, different prefix |
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 guides to high-voltage chip resistors and to Walsin automotive chip resistors explain the series labels.
Where does the 0.5 percent grade go in the automotive list?
It does not exist there. We counted the tolerance column across the 20,244 rows: the non-UL general series has 3,045 rows at plus or minus 0.5 percent, the non-UL automotive series has 0, and it has 3,045 rows at plus or minus 2 percent where the general series has 0.
The two counts are equal, which suggests a one-for-one change of grade, but the export does not say so. In the automotive series the tolerances split 3,045 at plus or minus 1 percent, 3,045 at plus or minus 2 percent and 713 at plus or minus 5 percent, 6,803 rows in all. The general series gives 3,045 at 0.5 percent, 6,114 at 1 percent and 1,278 at 5 percent, 10,437 in all. We have not seen this swap counted anywhere.
How many automotive high-voltage rows have a general-purpose twin?
Most do, but not the 2 percent rows. We matched each automotive row to a general row on size, resistance, rated power and tolerance: all 3,045 rows at 1 percent and all 713 at 5 percent have a twin, and none of the 3,045 rows at 2 percent does, because the general list has no 2 percent grade.
So an engineer moving an automotive 2 percent part to a general-purpose design has no same-tolerance row to land on, and one moving the other way must choose between 1 percent and 0.5 percent. The export carries no working-voltage column for either series, so no row can be matched on voltage from the export. The UL safety rows (1,502 each, general and automotive) run only at 1 and 5 percent and start at 100 kilohm.
What does the Hong Kong shelf hold in high-voltage resistors?
None. Of the 1,125 distinct part numbers on our stock list as at 23 September 2026, 0 appear among the 20,244 high-voltage resistor rows, although 254 are chip resistors in other series.
Every part in this post is therefore a to-order enquiry. The ready-stock list is a dated snapshot, never live-synced, and the chip resistor range lists the families. We give no lead time and no stock promise.
What will we not tell you about Slovak automotive electronics?
Anything about your platform, your qualification or your approved vendor list. Of the 20,244 high-voltage rows, none states a working voltage, and we hold no datasheet for the series, so every count here is catalogue coverage, not suitability for a battery or charger.
We hold no ISO 9001 or IATF 16949 certificate, and AEC-Q200 is not a claim Venatech makes of any part; ask for the qualification report for the exact part number. We hold no office, entity or stock in Slovakia; 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.
Why do buyers in Slovakia choose Venatech?
Because we name the swap. Venatech Limited is an authorised Walsin distributor in Hong Kong, and the Walsin high-voltage resistor lists hold 20,244 part numbers, 6,803 of them in the non-UL automotive series, where the 0.5 percent grade does not exist.
A Slovak buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and tells you which tolerance step is missing before a drawing is released. 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.
How can Venatech help a Slovak automotive electronics 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 0805, 1 megohm, automotive, plus or minus 1 percent brief returned 1 exact part among 8 part numbers at the value, none stocked. 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 Slovak automotive electronics maker, a high-voltage divider is a tolerance question: the automotive series offers 1, 2 and 5 percent, never 0.5 percent, and 3,045 rows each sit either side of that swap. Name the series, the tolerance and the power, not just the value.
Send us one high-voltage resistor line from your BOM, with the series, tolerance and rated power you can accept, and we will return the Walsin parts with every difference stated. If your drawing says 0.5 percent and automotive, do you know that no Walsin automotive-series row offers both?

Frequently asked questions
How many cars did Slovakia produce in 2025?
A TASR report of 13 January 2026, citing the Slovak automotive association ZAP, gave about 1.07 million cars on preliminary figures, or 196 vehicles per 1,000 inhabitants, up from roughly one million in 2024. These are the association’s figures, not ours.
What did Reuters report about Volvo Cars in Kosice?
On 4 July 2025 Reuters reported that Volvo moved large-scale production at its Kosice plant, then under construction, to early 2027, with planned capacity of about 250,000 cars a year, and that Polestar intended to build the Polestar 7 there from 2028. We found no later update.
Does Walsin offer an automotive high-voltage resistor at plus or minus 0.5 percent?
Not in the export. The non-UL general series has 3,045 rows at plus or minus 0.5 percent; the non-UL automotive series has none and instead has 3,045 rows at plus or minus 2 percent. Check the datasheet for any exception.
Which Walsin automotive-series resistor matches 0805, 1 megohm, plus or minus 1 percent?
WK08V1004FTLJ matches on series, size, value, tolerance and 1/8 W rated power in the export. Its neighbours differ in tolerance, series or prefix. Confirm against the datasheet and qualify in your own circuit before design-in.
Do the Walsin high-voltage resistor rows state a working voltage?
No. None of the 20,244 rows has a working-voltage or overload-voltage column, so voltage cannot be matched from the export. Take it from the datasheet for the exact part number, and design the divider for the voltage across each resistor.
Do you hold stock or an office in Slovakia?
No. We hold no office, entity or stock in Slovakia; none of the 20,244 high-voltage rows is on our 23 September 2026 shelf snapshot. We hold no ISO 9001 or IATF 16949 certificate and give no legal, customs or conformity advice. Confirm with your compliance team.
