RL1210A241K from RUILON Shenzhen Ruilongyuan Elec, 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 | Terminal 1 | passive | One end-termination of the bidirectional, symmetrical MOV (RL1210A241K: varistor voltage 216~264V at 1mA, max 150VAC / 200VDC), interchangeable with the other terminal. |
| 2 | Terminal 2 | passive | Other end-termination of the bidirectional, symmetrical MOV (RL1210A241K: 150VAC / 200VDC max, 250A 8/20μs withstanding surge current), interchangeable with terminal 1. |
