RL1206A101K from RUILON Shenzhen Ruilongyuan Elec, in a 1206. 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 | Terminal 1 of the bidirectional, symmetrical MLV; RL1206A101K has a varistor voltage of 102~127.5 V at 1 mA, 60 VAC / 85 VDC maximum allowable voltage, and 280 V maximum clamping at 5 A (8/20μs). |
| 2 | 2 | passive | Terminal 2 of the bidirectional, symmetrical MLV; interchangeable with terminal 1, with 0.5 J maximum energy (10/1000μs) and 100 A withstanding surge current (8/20μs). |
