V9MLA0402NR
Littelfuse · Varistors · 0402
V9MLA0402NR from Littelfuse, in a 0402. 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 metal end termination (Ni barrier, matte tin) of the bidirectional varistor, rated VM(DC) 9.0 V, VM(AC) 6.5 V continuous, with typical leakage <5µA and max <20µA at VM(DC). |
| 2 | TERMINAL 2 | passive | Opposite metal end termination of the bidirectional varistor, interchangeable with the other terminal, with 8/20µs surge rating of 20 A and 10/1000µs energy rating of 0.05 J for the V9MLA0402N. |
