Walsin’s 755 chip resistors in 01005 are a single series, with tolerance no tighter than 1 percent and no TCR class tighter than 200 ppm. The smallest body with a 100 ppm class is 0201, which reaches 50 ppm; 25 ppm starts at 0603. None of the 01005 rows is on our Hong Kong list.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) chip resistor export: 234,401 distinct part numbers. This post is for a procurement or design engineer at an Indian medical device maker or contract manufacturer who has a miniature resistor line to second-source. Every Walsin part number below is real and every count is ours. Where it states a development, it names the source, the document date and the day we fetched it, 2 November 2026.
What did India’s medical devices scheme report in July 2026?
Twenty-seven projects were approved. Indian Pharma Post reported on 28 July 2026 that the medical devices production-linked scheme had approved 27 projects, 14 of them MSMEs, with 23 commissioned, actual investment of 1,153.07 crore rupees and incentives of 266.64 crore rupees released through FY25.
For a buyer, that is context and nothing more. A scheme count is not a component order, the article lists capital equipment and implants and names no part or supplier, and we draw no conclusion about which resistors any Indian company buys. We have no relationship with the publication, the ministry or any scheme participant.
| Point | What the source says | Source date | Match / mismatch |
|---|---|---|---|
| Approvals | 27 projects approved under the medical devices scheme, 14 of them MSMEs; 23 commissioned and 4 in implementation | Indian Pharma Post, 28 July 2026 | Match for context only |
| Investment | Actual investment 1,153.07 crore rupees against a scheme outlay of 3,420 crore; incentives of 266.64 crore released through FY25 | Indian Pharma Post, 28 July 2026 | Match for context; no part or supplier named |
| Products | Production begun for MRI and CT equipment, LINACs, mammography, C-arms, ultrasound, heart valves, stents and dialysis products | Indian Pharma Post, 28 July 2026 | Mismatch with any claim about wearables: none is listed |
| Segments | Four segments, the last covering all implants including implantable electronics | India Briefing, 17 December 2025 | Match for context; older than the approval count |
How many Walsin chip resistors come in 01005?
Seven hundred and fifty-five, in one series. We filtered all 234,401 distinct part numbers in Walsin’s own chip resistor export files for the size string 01005(0402) and found 755, all in the General Purpose thick-film group: 609 at 1 percent, 145 at 5 percent and 1 jumper, across 626 distinct resistance values. We then read the stock list as at 23 September 2026 against all 755 codes and found none.
The temperature class has three forms: 557 rows at 200 ppm or less, 135 at 300 ppm or less and 62 printed as a one-sided band, -200~+600, which is not a plus-or-minus figure at all. There is no tolerance tighter than 1 percent and no class below 200 ppm. Note the naming: the size string is imperial 01005 with the metric code 0402 in brackets, which is not the 0402 imperial body that Walsin writes 0402(1005). Our post on passive component case sizes, imperial and metric explains the doubled naming.
Where does a tighter resistor class start by body size?
At 0201 for 50 ppm and at 0603 for 25 ppm. We grouped all 234,401 rows by body and read the smallest TCR class in each: 01005 stops at 200 ppm, 0201 reaches 50 ppm on 686 rows, 0402 (1005 metric) also reaches 50 ppm, and 25 ppm appears only at 0603, 0805 and 1206 with 1,029 rows each. The 0201 body has the first 0.1 percent rows (1,142), but all of them are in the 200 ppm class.
| Walsin body (imperial, metric) | Rows | Tolerance range | Tightest TCR class | Rows at 100 ppm or tighter | Rows at 50 ppm or tighter | Rows at 25 ppm or tighter | On the list | Match / mismatch with a 1 percent, 100 ppm line |
|---|---|---|---|---|---|---|---|---|
| 01005 (0402 metric) | 755 | ±1% to ±5% | 200 ppm | 0 | 0 | 0 | 0 | Mismatch: no row at 100 ppm or tighter |
| 0201 (0603 metric) | 17,827 | ±0.1% to ±5% | 50 ppm | 1,577 | 686 | 0 | 4 | Match: 1,577 rows at 100 ppm or tighter |
| 0402 (1005 metric) | 27,961 | ±0.1% to ±5% | 50 ppm | 19,290 | 4,570 | 0 | 55 | Match: 19,290 rows at 100 ppm or tighter |
| 0603 (1608 metric) | 42,374 | ±0.1% to ±5% | 25 ppm | 30,178 | 6,523 | 1,029 | 78 | Match: 30,178 rows at 100 ppm or tighter |
| 0805 (2012 metric) | 38,044 | ±0.1% to ±5% | 25 ppm | 30,365 | 6,771 | 1,029 | 23 | Match: 30,365 rows at 100 ppm or tighter |
So a miniature line that needs both 0.1 percent and a tight drift class has no 0201 answer: the 0.1 percent rows are 200 ppm and the 50 ppm rows are 0.5 and 1 percent. We have not seen the tolerance and TCR ladder counted by body this way anywhere. Our post on what resistor TCR actually buys you explains how much drift a class permits.
Which worked part numbers show the match and the gaps?
Take a 10 kilohm, 1 percent, 100 ppm line from your bill of materials. Walsin has one 10 kilohm 1 percent row in 01005, WR01X1002FDL at 200 ppm, and the first matches at 100 ppm or tighter are MR02X1002FAL and WK02K1002FAL in 0201 and WR04X1002FTL in the larger 0402. Only one 0201 10 kilohm part, WR02X1002FAL, is on the Hong Kong list, and it is the 200 ppm part.
| Walsin part | Body, series | Tolerance, TCR, power | Match / mismatch | Your incumbent |
|---|---|---|---|---|
WR01X1002FDL |
01005, General Purpose | ±1%, 200 ppm, 1/32 W | Match on 10 kohm and 1 percent; mismatch on TCR: 200 ppm against 100; the only 10 kohm 1 percent row in 01005; not stocked | |
WR02X1002FAL |
0201, General Purpose | ±1%, 200 ppm, 1/20 W | Match on value and tolerance; mismatch on TCR: 200 ppm; one of 4 0201 codes on the list as at 23 September 2026 | |
MR02X1002FAL |
0201, General Purpose (Automotive) | ±1%, 100 ppm, 1/20 W | Match on value, tolerance and 100 ppm; the automotive series, with Walsin’s wording compliant rather than certified; not stocked | |
WK02K1002FAL |
0201, High Precision TC50 | ±1%, 50 ppm, 1/20 W | Match on value and tolerance; tighter on TCR (50 ppm); not stocked | |
WR04X1002FTL |
0402 (1005 metric), General Purpose | ±1%, 100 ppm, 1/16 W | Match on value, tolerance and 100 ppm; mismatch on body: a larger footprint; not stocked |
The last column is for your incumbent part. We hold the two Walsin chip resistor datasheets for the MR and WR series; they cover the general-purpose and automotive lines in this table and not the High Precision TC50 line, so the WK02K1002FAL figures are from the export alone.
What will we not tell you about India?
Anything about Indian medical device rules, licensing, customs or import duty. We hold no office, entity or stock in India; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We state no duty, border procedure, transit time or carrier, and we give no legal, customs, regulatory or compliance advice; confirm with your compliance team.
We also say nothing about any imaging system, implant or wearable design, or whether a Walsin resistor suits a clinical environment. Our export contains no price, lead time or stock figure for these rows, and we publish none.
Why do buyers in India choose Venatech?
Because we show where a candidate differs and then sell the part. Venatech Limited is an authorised Walsin distributor in Hong Kong, which you can confirm with Walsin, and its chip resistor data runs from 755 miniature 01005 rows to 42,374 in 0603, in 14 series groups.
Our free cross-reference tool, VenaMatch, decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and prints match and mismatch fields so the gap is visible before the order. We work from Hong Kong and welcome small lots, which suits a prototype run or a contract manufacturer more than a reel buyer. The ladder above is the standard we keep: where a tighter class stops, we say so before you design it in.
How can Venatech help an Indian medtech buyer?
Start with the incumbent part number. Paste it into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts and lists Walsin candidates with match and mismatch fields, or upload a list to the BOM checker, up to 500 part numbers. The Hong Kong ready-stock list is a dated snapshot, 23 September 2026, never live-synced. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. You can request a quote through the site.
A worked example from our own export: a 10 kilohm, 1 percent, 100 ppm line in a compact body maps to MR02X1002FAL in 0201, with the 50 ppm option WK02K1002FAL beside it, and to WR04X1002FTL if the board can take 0402. Our chip resistor range lists the families. We hold neither ISO 9001, IATF 16949 nor ISO 13485. Qualification stays with you.
The short version
For a miniature resistor line, read the class before the body. Walsin’s 01005 is one series at 1 or 5 percent and 200 ppm or looser; 100 ppm starts at 0201, 50 ppm is available there on 686 rows, and 25 ppm starts at 0603. None of the 755 01005 rows is on the Hong Kong ready-stock list as at 23 September 2026.
Send us one miniature resistor from your bill of materials and we will return the Walsin parts with every difference stated. Is 200 ppm good enough for the circuit, or is the tolerance the real limit?

Frequently asked questions
How many Walsin chip resistors are in 01005?
Seven hundred and fifty-five in the export, all in one General Purpose series: 609 at 1 percent, 145 at 5 percent and 1 jumper, across 626 resistance values. None is on the Hong Kong ready-stock list as at 23 September 2026.
What is the tightest TCR in Walsin’s 01005 resistors?
200 ppm or less on 557 rows. The other rows are 300 ppm or less (135) or a one-sided band from minus 200 to plus 600 ppm (62). No 01005 row offers 100 ppm, and none is tighter than 1 percent tolerance.
Which body is the smallest with a 100 ppm class? It has 1,577 rows at 100 ppm or tighter, 686 of them at 50 ppm. The first 25 ppm rows are in 0603, 0805 and 1206 with 1,029 each. The 0.1 percent rows at 0201 are all in the 200 ppm class. Does Walsin say these resistors suit medical devices?
Not in the documents we hold. None of the Walsin pages we hold states a medical use or qualification, and Venatech holds no ISO 13485 certification. Confirm suitability against Walsin’s datasheet and qualify the part in your own circuit.
What did the July 2026 scheme report say about components?
Nothing. It reported 27 approved projects and 1,153.07 crore rupees of investment, listing imaging equipment, heart valves, stents and dialysis products. It names no part or supplier, so we draw no conclusion about resistors.
Can you advise on Indian medical device rules or customs?
No. We hold no office, entity or stock in India and we give no legal, customs or regulatory advice; confirm with your compliance team. We supply Walsin parts from Hong Kong in small lots, and qualification stays with you.
