KUU · Varistors · 0402
KRS04A052L5F from KUU, 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 | Terminal electrode (Ag inside, Ni-Sn plated outside) of the bidirectional chip varistor, rated 5 V DC (12.7 V AC RMS) max working voltage, 31.0-38.0 V varistor voltage at 1 mA DC. |
| 2 | 2 | passive | Second terminal electrode of the non-polar chip varistor, interchangeable with the other terminal, with 58 V max 8/20 µs clamping voltage and 1 A peak surge current. |
