# 1808HC102KAT1A

**Kyocera AVX** · Multilayer Ceramic Capacitors MLCC - SMD/SMT · 1808

1808HC102KAT1A from Kyocera AVX, in a 1808. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First terminal of the 1808 chip capacitor, plated Ni and Sn (RoHS), with terminal length 0.75 ± 0.35 mm (0.030 ± 0.014 in); non-polarized, so the two terminals are interchangeable. |
| 2 | 2 | passive | Second terminal of the 1808 chip capacitor, plated Ni and Sn (RoHS), with terminal length 0.75 ± 0.35 mm (0.030 ± 0.014 in); non-polarized, so the two terminals are interchangeable. |
