**Littelfuse** · Varistors · 1206

V26MLA1206NH from Littelfuse, 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 | Terminal 1 | passive | One nickel-barrier end termination of the bidirectional varistor, rated 26 V DC / 20 V AC continuous working voltage, 150 A (8/20µs) surge current and 0.600 J (10/1000µs) energy. |
| 2 | Terminal 2 | passive | Second end termination of the bidirectional varistor (interchangeable with the first), clamping at a maximum of 60 V at 1 A (8/20µs) with 29.5 V to 38.5 V nominal varistor voltage at 1 mA DC. |
