**TDK** · Varistors · 0402

AVRM1005C6R8NT331N from TDK, 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 | First terminal electrode of the non-polar varistor, with 6.8 V (4.76 to 8.84 V) varistor voltage at 1 mA, 3.5 V maximum DC circuit voltage, 15 V clamping at 1 A (8/20 µs) and 8 kV IEC61000-4-2 ESD tolerance; connect to the protected line. |
| 2 | Terminal 2 | passive | Second terminal electrode of the non-polar varistor (either terminal can go to ground), with 330 pF (231 to 429 pF) capacitance and 24 A maximum 8/20 µs surge current. |
