VCAS121018J390RP from Kyocera AVX, in a 1210. 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 | One Ni/Sn plated termination of the bi-directional varistor, rated 18 Vdc / 13 Vac working voltage, 25.5 V ±10% typical breakdown at 1 mA and 42 V max clamping at 5 A. |
| 2 | 2 | passive | Second Ni/Sn plated termination of the bi-directional varistor (interchangeable with the other terminal), rated 500 A peak (8x20 µs), 1.6 J transient energy (10x1000 µs) and 3 J load dump energy. |
