# HMK212BC7105KGHTE

> **Renamed by the maker.** TAIYO YUDEN renamed this part. Its spec sheet is titled "MCASH21GBC7105KTCA01 (Previous PN: HMK212BC7105KGHTE)" (p.1). Successor part numbers with the same ratings and size, per Taiyo Yuden's rename: MCASH21GBC7105KTCA01 (AEC-Q200, Mass Production (Preferred) on the spec sheet), MBASH21GBC7105KTCA01, MCASH21GBC7105KTCA1J and MMASH21GBC7105KTCA01 (the last three from part-reviewer's lookup, not printed on this sheet). The DC-bias and temperature curves are charts on p.2 of the spec sheet (linked below); their values are not transcribed here.


**Taiyo Yuden** · Multilayer Ceramic Capacitors MLCC - SMD/SMT · 0805

HMK212BC7105KGHTE from Taiyo Yuden, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). The symbol is generated from that pin table, the footprint is an Adom_Gen land derived from the manufacturer drawing, and the 3D model is generated to fit it.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Terminal 1 of an unpolarised multilayer ceramic capacitor (1 uF ±10%, 100 V, X7S, 0805/2012); either orientation. |
| 2 | 2 | passive | Terminal 2 of an unpolarised multilayer ceramic capacitor (1 uF ±10%, 100 V, X7S, 0805/2012); either orientation. |

## CAD (Adom-generated)

- Symbol: `HMK212BC7105KGHTE`
- Footprint: `Adom_Gen:TAIYO_YUDEN_HMK212_fd7182`
- 3D model: generated to fit the land (STEP)

## Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

- **Datasheet:** [Taiyo Yuden datasheet](https://ds.yuden.co.jp/TYCOMPAS/ut/specSheet?pn=MCASH21GBC7105KTCA01) (3 pp, sha256 `ba7d6a3a006d16ee`, retrieved 2026-11-12, tier: manufacturer)
- **Extractor:** `ds2sf` (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
- **CAD:** symbol generated from the datasheet pin table; footprint an Adom_Gen land derived from the manufacturer drawing; 3D model generated to fit that land. Land: TAIYO YUDEN's own land pattern for this case, the 'Land Pattern(DXF)' file TY-COMPAS serves for MCASH21GBC7105KTCA01 (the renamed HMK212BC7105KGHTE; same L/W/T/e). DXF in mm ($INSUNITS 4): layer L1 pads x -1.3..-0.5 and 0.5..1.3, y -0.625..0.625, i.e. 0.80 x 1.25 at x +/-0.90; layer Resist 0.90 x 1.35 (mask 0.05 per side); layer Comp body 2.0 x 1.25. KiCad C_0805_2012Metric (1.0 x 1.45 at +/-0.95) is not used.
