RL0805A431K from RUILON Shenzhen Ruilongyuan Elec, in a 0805. 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 end-cap terminal of the bidirectional, symmetrical varistor (RL0805A431K: varistor voltage 387~473 V at 1 mA, max allowable 275 VAC / 350 VDC, max clamping 710 V at 10 A 8/20μs). |
| 2 | 2 | passive | Other end-cap terminal of the bidirectional, symmetrical varistor, interchangeable with the first (RL0805A431K: max energy 0.1 J 10/1000μs, withstanding surge current 10 A 8/20μs). |
