**INPAQ** · Varistors · 0402

MLVG04021R0UV18CP from INPAQ, 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 | 1 | passive | First terminal of the bidirectional varistor (the part is non-polarised), rated 18 VDC maximum operating voltage, 46~60 V varistor voltage at 1 mA and 110 V clamping at 0.5 A 8/20us, with 1.0 pF capacitance. |
| 2 | 2 | passive | Second terminal of the bidirectional varistor (the part is non-polarised), electrically interchangeable with the other terminal, with the same 18 VDC rating, 46~60 V varistor voltage and 1.0 pF capacitance. |
