India sold 36,911 electric cars in October 2026, and every one carries dozens of AEC-Q200 MLCC positions. In the Walsin Technology (Walsin) export, AEC-Q200 X7R at 100 V stops at 100 nF in 0603 and 0805; a 1 µF, 100 V brief starts at 1206, with 4 qualified-series parts and none on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at an Indian supplier of on-board chargers, DC-DC converters, battery electronics or body controllers who must specify an AEC-Q200 MLCC on a 48 V or 12 V rail with margin. We parsed the Walsin MLCC export, 00_ALL_MLCC_parts_combined.xlsx (24,026 rows, 23,601 distinct part numbers), and our stock list as at 23 September 2026 on 11 November 2026. Every part number below is real. The market figures are Autocar India’s, fetched today.
What did India’s October 2026 electric car figures show?
A fifth straight month above 30,000. According to Autocar India on 4 November 2026, citing Vahan registration data, India sold 36,911 electric cars in October 2026, up 76 percent from 20,954 in October 2025, and 293,877 in January to October 2026.
The same report put Tata Motors at 14,654 units, Mahindra at 8,541 and JSW MG Motor at 5,938 for the month, and called October the second-highest month of 2026 after September’s 38,335. Those are the publication’s figures, not ours. The conclusion we draw is narrower: more electric cars mean more boards that an automotive customer will ask to be built with AEC-Q200 parts. We have no relationship with any of these carmakers and say nothing about what they or their suppliers buy.
What does an AEC-Q200 MLCC requirement change for an Indian EV supplier?
It narrows the catalogue sharply. We counted 854 distinct Walsin X7R part numbers rated 100 V; only 167 of them, about 20 percent, sit in the two series Walsin labels as qualified to AEC-Q200, the MT series and the ST soft-termination series.
A commercial 100 V X7R search therefore shows five parts for every one an automotive customer will accept on the drawing. Walsin’s own series names in the export read “Qualified to AEC-Q200” for MT and ST, and we hold their datasheets, 11_Automotive_MT.pdf and 12_Soft_Term_Automotive_ST.pdf; qualified is not certified, and we do not upgrade the claim. A third automotive family, the MG series (datasheet 14_MG_Series_High_Reliability.pdf), is labelled in the export as “without AEC-Q200 certification”, so it is not a substitute where the drawing names the standard. Our post on AEC-Q200 MLCC: MT versus MG explains that split, and what AEC-Q200 actually certifies explains why you should request the qualification report for the exact part number.
How far does a Walsin AEC-Q200 MLCC go at 100 V X7R?
Not past 100 nF until 1206. We grouped the 167 AEC-Q200 X7R parts at 100 V by case: 5 in 0402 reach 1 nF, 54 in 0603 and 49 in 0805 each stop at 100 nF, 47 in 1206 reach 2.2 µF, 11 in 1210 reach 4.7 µF and 1 part in 2220 reaches 10 µF.
| Case | AEC-Q200 X7R parts at 100 V | Highest capacitance | On shelf 23 Sep 2026 |
|---|---|---|---|
| 0402 | 5 | 1 nF | 0 |
| 0603 | 54 | 100 nF | 0 |
| 0805 | 49 | 100 nF | 0 |
| 1206 | 47 | 2.2 µF | 0 |
| 1210 | 11 | 4.7 µF | 0 |
| 2220 | 1 | 10 µF | 0 |
We have not seen this ladder counted anywhere. It matters on a 48 V auxiliary rail in an Indian EV, where a designer often wants 1 µF of local decoupling in the smallest case. At 100 V and AEC-Q200, the 0805 cannot give it; the smallest Walsin answer is 1206. Remember too that a 100 V rating is not a working voltage, and Class II capacitance falls with applied DC voltage. Our post on MLCC DC bias and voltage derating covers that loss.
Which Walsin parts answer a 1 uF, 100 V, X7R brief, and what differs?
Twenty-one part numbers, four of them AEC-Q200. We filtered the export for X7R, 1 µF, 100 V and found 22 rows holding 21 distinct part numbers: 9 General Purpose, 3 MT, 1 ST, 2 MG, 3 Big Sizes and 3 SH soft-termination; the only one on our shelf is the General Purpose 1210 part, 1210B105K101.
The last column is for your incumbent.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with a 1 µF, 100 V, X7R, plus or minus 10 percent, AEC-Q200, 1206 brief | Your incumbent |
|---|---|---|---|---|
MT31B105K101 |
MT series (AEC-Q200), 1206, X7R, 1 µF, plus or minus 10%, 100 V | No | Match on every field | |
MT31B105J101 |
MT series (AEC-Q200), 1206, X7R, 1 µF, plus or minus 5%, 100 V | No | Mismatch: tolerance plus or minus 5 percent, tighter | |
ST31B105K101 |
ST series (AEC-Q200, soft termination), 1206, X7R, 1 µF, plus or minus 10%, 100 V | No | Match on the electrical fields; mismatch: soft termination | |
MG32B105K101 |
MG series (labelled without AEC-Q200), 1210, X7R, 1 µF, 100 V | No | Mismatch: no AEC-Q200 label and case 1210 | |
1206B105K101 |
General Purpose, 1206, X7R, 1 µF, plus or minus 10%, 100 V | No | Mismatch: commercial series, not AEC-Q200 | |
1210B105K101 |
General Purpose, 1210, X7R, 1 µF, plus or minus 10%, 100 V | Yes | Mismatch: commercial series and case 1210 |
A match in the table is a match on export fields, no more. Confirm against both datasheets and qualify in your own circuit. The two MG rows in this brief print their tolerance as a bare “-0.1” rather than plus or minus 10 percent; we read the part-number tolerance letter, K, instead.
Why can one Walsin part number carry two heights?
Because the export lists some part numbers more than once. We checked the 1 µF, 100 V brief and found 1812B105K101 on two rows, one 2.00 plus or minus 0.20 mm thick and one 2.50 plus or minus 0.30 mm; across the whole MLCC export, 399 part numbers sit on 824 rows.
The part number alone does not tell you the height. An Indian EV supplier with a height-limited enclosure or a fixed pick-and-place nozzle should state the maximum thickness on the purchase order, not just the code. We read the thickness column of every row we quote, and we can tell you which thickness a quoted lot carries before you commit. This is the same trap that makes a pasted BOM look clean when it is not, and it is one reason our cross-reference tool lists differences rather than hiding them.
What does the Hong Kong shelf hold for AEC-Q200 MLCC?
None of the qualified-series parts. Our stock list as at 23 September 2026 holds 1,125 part numbers; we counted 0 of the 2,173 MT parts, 0 of the 118 ST parts and 0 of the 785 MG parts on it, and 1 of the 21 parts in the 1 µF, 100 V brief, the commercial 1210B105K101.
The ready stock list is a dated snapshot, never live-synced, and it counts part numbers, not pieces. For an AEC-Q200 line, ask for a to-order enquiry by exact part number through the site. We give no lead-time or stock promise. We hold no office, entity or stock in India; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no customs or legal advice on imports into India; confirm with your compliance team. The MLCC range lists every family.
How can Venatech help an Indian EV electronics buyer?
How Venatech helps starts with a free paste box. The cross-reference tool, VenaMatch, decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts; paste up to 500 part numbers or drop an Excel or CSV file, filter by commercial or automotive grade, and every field comes back marked match or mismatch. Load a whole BOM for a check, and see the ready-stock list, a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 1 µF, 100 V X7R brief returned 21 part numbers, 4 in AEC-Q200 series, 1 exact AEC-Q200 match in 1206, and 1 commercial part on the shelf. Venatech Limited is authorised for Walsin only; Stackpole and Viking are lines we supply. We serve from Hong Kong, welcome small lots, and you request a quote through the site. Qualification stays with you.
The short version
Autocar India counted 36,911 electric cars sold in October 2026. For the capacitors behind them, the Walsin AEC-Q200 MLCC ladder at 100 V X7R stops at 100 nF in 0603 and 0805, so 1 µF needs 1206, where MT31B105K101 matches the full brief. None of the qualified-series parts is on our shelf.
Send us one automotive capacitor line from your BOM, with the case and height you must keep, and we will return the Walsin parts with every difference stated. Has your 100 V decoupling been drawn in a case that AEC-Q200 parts can actually fill?

Frequently asked questions
How many electric cars did India sell in October 2026?
Autocar India reported on 4 November 2026, citing Vahan data, that India sold 36,911 electric cars in October 2026, up 76 percent from 20,954 a year earlier, and 293,877 from January to October. These are the publication’s figures, not Venatech’s.
How many Walsin AEC-Q200 MLCC are X7R at 100 V?
We counted 167 distinct part numbers in the MT and ST series, out of 854 Walsin X7R part numbers rated 100 V. The MG series is labelled without AEC-Q200 and is not counted. Request the qualification report for the exact part number before design-in.
What is the smallest Walsin AEC-Q200 case that reaches 1 µF at 100 V X7R? The 0603 and 0805 AEC-Q200 parts at 100 V X7R stop at 100 nF in the export. In 1206 the MT series reaches 2.2 µF and MT31B105K101 matches a 1 µF, plus or minus 10 percent brief. Is MG series the same as AEC-Q200 for an Indian EV customer?
No. The export labels the MG series as automotive caps without AEC-Q200 certification. If your customer’s drawing names AEC-Q200, use the MT or ST series and confirm with the customer. Confirm against both datasheets and qualify in your own circuit.
Does Venatech hold AEC-Q200 MLCC in stock in Hong Kong?
Not in the snapshot dated 23 September 2026: 0 of 2,173 MT, 0 of 118 ST and 0 of 785 MG part numbers are on it. Ask for a to-order enquiry through the site; we make no lead-time or stock promise.
