# V33MLA1206NH

**Littelfuse** · Varistors · 1206

V33MLA1206NH 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 | 1 | passive | One metal end termination of the leadless 1206 (3.2 x 1.6 mm) chip; the varistor clamps bi-directionally, so either end may be used, with VM(DC) 33 V and VM(AC) 26 V maximum continuous working voltage. |
| 2 | 2 | passive | Second metal end termination of the leadless 1206 chip, interchangeable with the other end because clamping is inherently bi-directional, with 180 A (8/20µs) maximum non-repetitive surge current and 0.8 J (10/1000µs) maximum surge energy. |
