Appliance electronics for Egypt now include refrigerator control boards, and the Walsin Technology (Walsin) export lists 20,244 high-voltage thick film chip resistors with no working-voltage column. All 2,657 of the plus or minus 5 percent parts carry a space in the part number, and none of the 20,244 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 an Egyptian appliance maker or board assembler who is crossing a high-voltage resistor on a mains-connected control board. 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 Daily News Egypt report about Haier Egypt’s refrigerator phase, and why does a component buyer care?
It reported a second production phase due this month. According to Daily News Egypt on 10 September 2026, Haier Egypt’s 200,000 square metre complex in 10th of Ramadan City has four factories with capacity above 1 million appliances a year, about 30 percent exported, and a second phase due to open in November adds refrigerators and freezers with annual capacity above 500,000 units.
The same report gives local component content of 65 percent for household air conditioners and 42.6 percent for VRF central systems. Those are the report’s figures, not ours. The conclusion we draw is ours: a refrigerator and freezer line means controller and compressor-drive boards, and a stated push on local content means more board-level bills of materials being worked through in Egypt. We have no relationship with Haier or any Egyptian appliance maker, and we say nothing about what any of them buys.
Which Walsin high-voltage chip resistors match a 1 megohm, plus or minus 1 percent, 1206 brief, and what differs?
Five part numbers match on value, tolerance and size, across four series. We parsed the 20,244 high-voltage rows and found 5 at 1 megohm, plus or minus 1 percent, in 1206: all rated 1/4 W and 100 ppm per degree Celsius or better, differing in series (standard, automotive, UL safety certification and its automotive form) and in the WK or WF prefix.
A sixth row, the plus or minus 5 percent form, is shown to make the point about spaces. The reader’s incumbent goes in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
WK12V1004FTL |
High Voltage, 1206, 1 megohm, plus or minus 1%, 1/4 W, 100 ppm or better | No | Match on size, value, tolerance, power and temperature coefficient | |
WF12V1004FTL |
High Voltage (standard series), 1206, 1 megohm, plus or minus 1%, 1/4 W | No | Match on the export fields; mismatch in prefix (WF, not WK), meaning not stated in the export | |
WK12V1004FTLJ |
High Voltage (Automotive), 1206, 1 megohm, plus or minus 1% | No | Match on the electrical fields; mismatch in series (automotive, J suffix) | |
WF12N1004FTL |
High Voltage UL Safety Certification, 1206, 1 megohm, plus or minus 1% | No | Match on the electrical fields; mismatch in series (UL safety certification) | |
WF12N1004FTLJ |
High Voltage UL Safety Certification (Automotive), 1206, 1 megohm, plus or minus 1% | No | Match on the electrical fields; mismatch in series | |
WF12N105 JTL |
High Voltage UL Safety Certification, 1206, 1 megohm, plus or minus 5%, 200 ppm | No | Mismatch: tolerance is plus or minus 5%, the coefficient is looser, and the part number holds a space |
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 low-ohm current sense, thick film against metal shows the same field-by-field method on a different resistor family, and anti-surge chip resistors covers the neighbouring pulse-rated family.
Does the Walsin export state a working voltage for its high-voltage chip resistors?
No. We opened all 20,244 high-voltage rows: the export has 10 columns and none holds a working or maximum voltage, so the voltage a part may see has to come from a datasheet, and the 28 Walsin datasheets we hold include only 2 chip resistor families, neither of them a high-voltage series.
What the export does give is size, power and tolerance. The 20,244 rows split into 4,118 each at 2512, 2010 and 1206, 3,966 at 0805 and 3,924 at 0603, with rated power from 1/10 W to 1 W. A voltage rating is a different question from a power rating, and a divider across a mains rail has to respect both. We have not seen this gap counted anywhere. Read the series datasheet on Walsin’s own site before you fix a footprint, and the chip resistor range lists the families.
Why do 2,657 Walsin high-voltage resistor part numbers contain a space?
Because every plus or minus 5 percent part is written with one. We counted spaces in all 20,244 part numbers: 2,657 (13.1 percent) contain one, and they are exactly the 2,657 rows with plus or minus 5 percent tolerance; none of the 11,497 plus or minus 1 percent, 3,045 plus or minus 0.5 percent or 3,045 plus or minus 2 percent rows has one.
Across all 234,815 chip resistor rows, 39,576 part numbers hold a space, so this is one slice of a wider habit. A part number with a space can fail to paste, sort or join in a BOM or ERP field. Strip or preserve the space the same way on both sides of any comparison, and check the result in the cross-reference tool before you trust a lookup that returned nothing.
What does the Hong Kong shelf hold in high-voltage chip resistors?
Nothing in this family. Of the 20,244 high-voltage chip resistor part numbers, 0 are on our stock list as at 23 September 2026; the list holds 254 chip resistor lines, 250 of which match a row in the export, all in other series.
The ready stock list is a dated snapshot, never live-synced. If your brief needs a high-voltage value, ask for a to-order enquiry through the site and we will say plainly what we hold and what we do not.
What will we not tell you about appliance control boards?
Anything about your mains design, your insulation coordination or your approvals. Of the 28 Walsin datasheets we hold, 26 cover MLCC and 2 cover chip resistors, so for the 20,244 high-voltage rows every count here is catalogue coverage, not suitability.
Two series carry the words UL Safety Certification in the export. The five named third-party certificates in the documents we hold are for safety capacitors, not resistors, so we cannot give you a UL file number for these resistors, and we make no claim that any part suits a refrigerator. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Egypt; 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 an Egyptian appliance 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 1 megohm, plus or minus 1 percent, 1206 brief returned 5 parts in 4 series, none stocked, so the answer to an Egyptian board buyer is a shortlist and an honest gap, not a promise. 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 an Egyptian appliance board, a high-voltage resistor is a series question and a voltage question: 5 Walsin parts at one value in four series, no voltage column in 20,244 rows, a space in all 2,657 plus or minus 5 percent part numbers, and none on the shelf. Check the series, then the datasheet.
Send us one high-voltage resistor line from your BOM with the tolerance and size you can accept, and we will return the Walsin candidates with every difference stated. Do you know which series, and which voltage, your incumbent is rated for?

Frequently asked questions
What did Daily News Egypt report about Haier Egypt in September 2026?
On 10 September 2026 it reported a 200,000 square metre complex in 10th of Ramadan City with four factories, capacity above 1 million appliances a year and about 30 percent exported, and a second phase in November adding refrigerators and freezers above 500,000 units a year. These are the report’s figures, not ours.
Which Walsin high-voltage chip resistors match 1 megohm, plus or minus 1 percent, in 1206?
Five: WK12V1004FTL, WF12V1004FTL, WK12V1004FTLJ, WF12N1004FTL and WF12N1004FTLJ, all rated 1/4 W. They differ in series (standard, automotive, UL safety certification, and its automotive form) and prefix. None is on our shelf.
Does the Walsin export give a working voltage for high-voltage chip resistors?
No. We found no voltage field in any of the 20,244 high-voltage rows, only size, power, tolerance and temperature coefficient. Take the voltage from the series datasheet on Walsin’s site and qualify in your own circuit.
Why do some Walsin high-voltage part numbers contain a space?
All 2,657 plus or minus 5 percent rows are written with a space, for example WF12N105 JTL, and no other tolerance is. Normalise the space the same way on both sides before comparing BOM lines.
Are Walsin high-voltage chip resistors on the Hong Kong shelf?
No. None of the 20,244 high-voltage part numbers is on our stock list as at 23 September 2026. The snapshot is dated, not live, so ask for a to-order enquiry through the site.
Can you give a UL file number for the UL Safety Certification resistor series?
No. The export names the series, but the five named third-party certificates in the documents we hold are for safety capacitors. Ask for the certificate for your exact part number and confirm with your compliance team.
Do you hold stock or an office in Egypt?
No. We hold no office, entity or stock in Egypt; 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.
