A resistor array replaces four discrete chips with one part, and Walsin Technology (Walsin) lists 10,120 chip resistor arrays and networks, from 0201 x 2 to 0603 x 4; a 10 kilohm, four-element 0402 brief returns 10 of them, including anti-sulfur and automotive options. Venatech is Walsin’s authorised distributor in Hong Kong.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a hardware engineer or buyer in Gumi, South Korea, who is cutting placement count on pull-up, bus termination and LED driver positions. We parsed Walsin’s chip resistor exports (137 .xlsx files, 234,815 rows), and our stock list as at 23 September 2026. Every part number is real, and the market statement names its source and the day we fetched it.
What did Asia Economy report about Gumi’s electronics industry outlook for 2026?
A second quarter of improving sentiment. Asia Economy reported, from a survey of 100 Gumi manufacturers run on 1 to 12 December 2025, that Gumi’s business survey index for the first quarter of 2026 rose to 83 from 80, against a national average of 77, with the electrical and electronics sector also at 83, and that Gumi’s 2025 exports were about 28 billion US dollars.
The article gives the survey dates but no publication date; we fetched it on 11 November 2026. The figures are the survey’s, not ours, and an index below 100 still means more firms expect worse conditions than better. We read it simply: Gumi’s electronics base is steady, and steady production is when engineering teams have time to take cost and placement count out of a board. Resistor arrays are one of the easiest places to start.
How many Walsin chip resistor arrays are there, and in which formats?
10,120. We counted every Walsin series whose name includes Array or Network across the chip resistor exports: 10,120 distinct part numbers, 6,785 of them four-element arrays, 2,127 two-element, 1,110 eight-element and 98 networks.
| Format | Element count | Walsin part numbers |
|---|---|---|
| 0201 x 2 and 0201 x 4, flat | 2 and 4 | 388 |
| 0402 x 2 | 2 | 949 |
| 0402 x 4, convex and concave | 4 | 3,054 |
| 0603 x 2 | 2 | 984 |
| 0603 x 4, convex and concave | 4 | 3,537 |
| 0602 x 8, convex | 8 | 1,110 |
| 1206 network, convex | network | 98 |
Within those, 2,772 are anti-sulfuration arrays and 1,386 sit in Walsin’s automotive array series. Tolerance splits 7,741 at 1 percent and 2,362 at 5 percent. Our explainer on chip resistor arrays covers convex and concave terminals, and resistor arrays against discrete parts covers when an array pays off.
Which Walsin resistor arrays match a 10 kilohm, four-element 0402 brief?
Ten do. We filtered the arrays to 0402 x 4 and 10 kilohm and found 10 Walsin part numbers in four series: five at 1 percent and five at 5 percent, with anti-sulfur, automotive, convex and concave options. A typical pull-up brief asks for 1 percent and a convex terminal.
| Walsin part | Series | Terminal | Tolerance | TCR (ppm/C) | Match / mismatch with a 1%, convex brief | Your incumbent |
|---|---|---|---|---|---|---|
WA04X1002FTL |
Thick Film Array | Convex | 1% | 200 | Match | |
WA04X1002FTLJ |
Thick Film Array | Convex | 1% | 200 | Match, packaging variant | |
SA04X1002FTL |
Anti-Sulfuration Array | Convex | 1% | 300 | Match, sulfur-resistant | |
MA04X1002FTL |
Automotive Array | Convex | 1% | 300 | Match, automotive series | |
WA04T1002FTL |
Thick Film Array | Concave | 1% | 300 | Mismatch: concave terminal | |
WA04X103 JTL |
Thick Film Array | Convex | 5% | 200 | Mismatch: 5% tolerance | |
SA04X103 JTL |
Anti-Sulfuration Array | Convex | 5% | 300 | Mismatch: 5% tolerance |
All ten list 1/16 W per element in the export. Convex and concave terminals take different land patterns, so a concave part will not drop onto a convex footprint. Confirm against both datasheets and qualify in your own circuit.
When should a Gumi design use an anti-sulfur or automotive resistor array?
When the air or the customer asks for it. Our count shows 2,772 Walsin anti-sulfuration arrays and 1,386 automotive arrays, so both answers exist at 0402 x 4 and 0603 x 4 without changing to discrete parts.
Sulfur in the air, from rubber, industrial sites or some coatings, attacks the silver in a standard thick-film termination over time and opens the resistor. Industrial controllers, outdoor equipment and boards near rubber gaskets are the usual risk cases. The automotive array series suits boards built for vehicle customers; Walsin’s datasheets say AEC-Q200 compliant, not certified, so request the qualification report for the exact part number. Our note on anti-sulfuration resistor arrays covers the overlap, and the chip resistor range lists every family.
How does Venatech supply Walsin resistor arrays to Gumi from Hong Kong?
Through our authorised Walsin channel. Our stock list as at 23 September 2026 held one Walsin array line, WA04X300 JTL, a 30 ohm 0402 x 4 part at 5 percent; the 10 kilohm parts above are quoted to order: request a quote and we source them through our authorised Walsin channel.
That 30 ohm line is a common series-termination value on memory and display buses, so it suits a pilot board while production parts are quoted. We serve small lots from Hong Kong. The ready-stock list is a dated snapshot, never live-synced, and we give no stock or lead-time promise. We hold no ISO 9001 or IATF 16949 certificate of our own and give no customs advice; confirm import questions with your compliance team.
How Venatech helps: how can a Gumi team cross its resistor arrays?
Paste or upload. VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, marking each field as a match or a mismatch, so a Gumi team can check its arrays, and the discrete resistors it might fold into arrays, against Walsin’s 10,120 array part numbers.
Use the cross-reference tool for single parts or the BOM page for a whole board. Venatech is Walsin’s authorised distributor in Hong Kong; Stackpole and Viking are lines we supply. Ask for a quote through the site and we reply from Hong Kong.
The short version
Gumi’s electrical and electronics makers scored 83 on the first-quarter 2026 business survey index, per Asia Economy. For the pull-up and termination positions on their boards, we counted 10,120 Walsin chip resistor arrays and networks; a 10 kilohm 0402 x 4 brief returns 10 parts, with anti-sulfur and automotive options at 1 percent.
Send us the discrete resistor groups on your board and we will show which fold into a Walsin array, with every field difference marked. How many identical 0402 resistors sit side by side on your main board?

Frequently asked questions
How many chip resistor arrays does Walsin offer for electronics makers in Gumi, South Korea?
We counted 10,120 distinct Walsin chip resistor arrays and networks: 6,785 four-element, 2,127 two-element, 1,110 eight-element and 98 networks, from 0201 to 1206. Venatech, Walsin’s authorised distributor in Hong Kong, quotes all of them.
Which Walsin resistor array matches 10 kilohm, 0402 x 4, 1 percent?
WA04X1002FTL and WA04X1002FTLJ in the standard convex array series, SA04X1002FTL in the anti-sulfuration series and MA04X1002FTL in the automotive series. WA04T1002FTL is concave and needs a different land pattern. Confirm against both datasheets.
What is the difference between a convex and a concave resistor array?
The terminal shape. Convex terminals stand out from the body; concave terminals are recessed. Each needs its own land pattern, so a concave array will not drop onto a convex footprint even when resistance, tolerance and size match.
Does Walsin make anti-sulfur resistor arrays?
Yes. Our count shows 2,772 Walsin anti-sulfuration arrays, at 0402 and 0603 in two- and four-element formats. They suit boards exposed to sulfur from rubber, industrial air or some coatings.
Did Venatech hold Walsin resistor arrays in Hong Kong stock?
Our snapshot dated 23 September 2026 held WA04X300 JTL, a 30 ohm 0402 x 4 array at 5 percent. Other arrays are quoted to order through our authorised Walsin channel. We give no stock or lead-time promise.
What did Asia Economy report about Gumi in 2026?
From a survey of 100 Gumi manufacturers run on 1 to 12 December 2025, it reported a first-quarter 2026 business survey index of 83, up from 80, against a national 77, and 2025 exports of about 28 billion US dollars.
