**TDK** · Varistors · 0402

AVRM1005C270KT101N 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 | Non-polar varistor terminal (varistor voltage 27 V (24 to 30 V) at 1 mA, max continuous DC voltage 19 V, clamping voltage 44 V at 8/20 µs 1 A). |
| 2 | Terminal 2 | passive | Non-polar varistor terminal, interchangeable with the other terminal (varistor voltage 27 V (24 to 30 V) at 1 mA, max continuous DC voltage 19 V, 100 pF (70 to 130 pF) capacitance). |
