K0603ESDA-LC
KUU · Varistors · 0603
K0603ESDA-LC from KUU, in a 0603. 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/Ni/Sn three layers) of the bidirectional ESD varistor, rated 18 V DC max working voltage, 100-160 V varistor voltage at 1 mA, 200 V max clamping, and ESD contact discharge of 8 kV or more. |
| 2 | 2 | passive | Second terminal electrode (Ag/Ni/Sn three layers) of the bidirectional ESD varistor, interchangeable with the other terminal, with 5 uA max leakage at VDC and 0.5-1.5 pF capacitance at 1 MHz, 0.5 V. |
