# F0603G0R05FNTR

**Kyocera AVX** · Disposable Fuses · 0603

F0603G0R05FNTR from Kyocera AVX, 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 | One fuse terminal (LGA pad, Sn100 over nickel, 0.71±0.05 mm wide); F0603G0R05 is rated 0.050 A, 63 V, with 3.4 Ω max resistance at 0.1 x I rated and 250 mV max drop at rated current. |
| 2 | 2 | passive | The other fuse terminal (LGA pad, Sn100 over nickel); the fuse is non-polarized and has a fusing current of 0.125 A within 5 s and post-fusing resistance above 1 MΩ. |
