For an AEC-Q200 MLCC on a Bursa EV board, Walsin Technology (Walsin) lists 2,291 qualified part numbers: 2,173 in the MT series and 118 soft-termination ST parts. An 0805, 1 µF, X7R brief returns 10 of them. Venatech Limited, an authorised Walsin distributor in Hong Kong, crosses and quotes each one.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for hardware and sourcing engineers at automotive electronics suppliers around Bursa, Turkey, who place decoupling and filter capacitors on body, battery and charging electronics for EV programmes. We parsed the Walsin MLCC export 00_ALL_MLCC_parts_combined.xlsx (24,026 rows, 23,601 distinct part numbers) and our ready-stock list as at 23 September 2026. Every part number is real, and the market facts come from one report fetched on 11 November 2026.
How many EVs does Togg plan to build in Bursa?
Sixty thousand or more in 2026. According to electrive on 22 January 2026, Togg built around 40,000 vehicles in 2025 at its plant in Gemlik, Bursa Province, targets 60,000 or more in 2026, and plans capacity of 100,000 a year by the end of 2027, with a long-term goal of 175,000.
The same report says Togg passed 100,000 deliveries since the T10X launch in 2023, entered Germany in September 2025, and plans a third model, the T6, for 2027. Those are electrive’s figures, not ours. Our conclusion: a vehicle plant ramping by half in a year pulls its regional supplier base with it, and every module that base builds carries AEC-Q200 capacitors. We have no relationship with Togg and say nothing about what it buys.
How many AEC-Q200 MLCC does Walsin list?
2,291 distinct part numbers. We counted the two Walsin series qualified to AEC-Q200 in 00_ALL_MLCC_parts_combined.xlsx: 2,173 in the MT series and 118 in the ST soft-termination series, 1,286 of them C0G and 1,001 X7R, from 0201 to 2220 and from 10 V to 3 kV.
| Size | AEC-Q200 parts (MT plus ST) |
|---|---|
| 0201 | 204 |
| 0402 | 486 |
| 0603 | 619 |
| 0805 | 535 |
| 1206 | 339 |
| 1210 | 100 |
| 1812 to 2220 | 8 |
By voltage, 975 are rated 50 V, 410 are 100 V and 299 are 25 V, with 74 at 250 V and 68 at 630 V for high-voltage battery and charger positions. Our guide to what AEC-Q200 actually certifies explains the stress tests, and the MLCC range lists every family.
Which Walsin AEC-Q200 MLCC cross an 0805, 1 µF, X7R brief?
Ten part numbers. We filtered the 2,291 to 0805, 1 µF and X7R and found 10 Walsin AEC-Q200 part numbers: 9 MT parts from 10 V to 50 V in 5%, 10% and 20% tolerance, and 1 ST soft-termination part at 50 V.
The table takes a common brief, 0805, 1 µF, X7R, plus or minus 10%, 50 V, AEC-Q200, and shows the closest rows. Your incumbent goes in the last column.
| Walsin part | Series | Tolerance | Rated voltage | Thickness (mm) | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|---|---|
MT21B105K500 |
MT | ±10% | 50 V | 1.25 ±0.20 | Match on every field | |
ST21B105K500 |
ST (soft termination) | ±10% | 50 V | 1.25 ±0.30 | Match, adds flex-crack protection | |
MT21B105J500 |
MT | ±5% | 50 V | 1.25 ±0.20 | Match, tighter tolerance | |
MT21B105M500 |
MT | ±20% | 50 V | 1.25 ±0.20 | Mismatch: tolerance is wider | |
MT21B105K250 |
MT | ±10% | 25 V | 1.25 ±0.10 | Mismatch: lower voltage | |
MT21B105K160 |
MT | ±10% | 16 V | 1.25 ±0.10 | Mismatch: lower voltage |
A match is a match on export fields. An X7R 1 µF at 50 V loses capacitance with DC bias, so check Walsin’s datasheet curve at your rail voltage, and ask for the qualification report your customer requires.
What is the difference between Walsin MT, ST and MG automotive MLCC?
The qualification and the termination. In the export, the MT and ST series are labelled as qualified to AEC-Q200, ST adds a soft polymer termination, and the 785-part MG series is labelled automotive without AEC-Q200 certification.
For a Bursa supplier that difference decides which part number goes on a PPAP drawing. MT is the default automotive choice; ST suits boards near connectors, screw points or panel breaks where flex cracking is a risk; MG is for automotive-adjacent uses where the customer does not demand AEC-Q200. Our side-by-side of Walsin MT versus MG goes field by field. We do not certify parts; confirm qualification status against Walsin’s documents and with your compliance team.
How do Bursa suppliers get Walsin AEC-Q200 MLCC from Hong Kong?
By quote, through our authorised Walsin channel. Our ready-stock list as at 23 September 2026 is built for general-purpose lines, such as the 0805, 1 µF X7R parts 0805B105K250 and 0805B105K100; MT and ST automotive parts are quoted to order through our authorised Walsin channel.
That split is deliberate. Automotive builds want traceable date codes and one lot per programme, which is what an authorised channel provides; the commercial-grade shelf lines suit bench prototypes and non-automotive boards, not a vehicle build. The ready-stock list is a dated snapshot, never live-synced. We give no stock or lead-time promise.
How can Venatech help an EV electronics supplier in Turkey?
How Venatech helps: decode, cross, quote. Venatech Limited is the authorised Walsin distributor in Hong Kong, and VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, marking every field match or mismatch.
Paste up to 500 part numbers into the cross-reference tool, or upload a BOM. We serve small lots from Hong Kong and quote fast; request a quote through the site. Walsin is the line we are authorised for; Stackpole and Viking are lines we supply. We hold no IATF 16949 certificate and give no customs or type-approval advice.
The short version
Togg aims to lift Bursa output by half in 2026, and its supplier base builds on AEC-Q200 parts. Walsin covers that with 2,291 AEC-Q200 MLCC, 2,173 MT and 118 ST; an 0805, 1 µF, X7R brief returns 10 part numbers, two of which match a 50 V, 10% brief on every field.
Send us the automotive capacitor lines from your BOM with the rail voltage and the qualification your customer asks for, and we will return the Walsin MT and ST rows. Which of your 0805 positions sits next to a connector?

Frequently asked questions
How many EVs will Togg build in Bursa in 2026?
electrive reported on 22 January 2026 that Togg built around 40,000 vehicles in 2025 at Gemlik, Bursa, and targets 60,000 or more in 2026, with capacity of 100,000 a year planned by the end of 2027. These are the report’s figures.
How many AEC-Q200 MLCC does Walsin make?
We counted 2,291 distinct Walsin AEC-Q200 part numbers: 2,173 in the MT series and 118 in the ST soft-termination series, from 0201 to 2220.
Which Walsin part matches an 0805, 1 µF, X7R, 50 V AEC-Q200 capacitor?
MT21B105K500 matches on every export field, and ST21B105K500 matches with soft termination. Check DC-bias loss at your rail against Walsin’s datasheet.
Is the Walsin MG series AEC-Q200 qualified?
The export labels the 785-part MG series as automotive without AEC-Q200 certification. Use MT or ST where your customer requires AEC-Q200.
Can I buy Walsin automotive MLCC in small lots for Turkey?
Yes. Venatech Limited, an authorised Walsin distributor in Hong Kong, quotes MT and ST parts to order in small lots. We give no lead-time promise and no customs advice; confirm with your compliance team.
Does Venatech hold IATF 16949?
No. We hold no IATF 16949 certificate. Ask us for Walsin’s own qualification documents for the part numbers you need.
