0603FA-2HF

prosemi · Disposable Fuses · 0603

0603FA-2HF from prosemi, 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 end terminal of the 2.00 A fast-acting fuse (63 V rating, 63V@50A interrupting rating, typical cold resistance 0.071 ohm); non-polarized, interchangeable with the other terminal.
2 2 passive Other end terminal of the 2.00 A fast-acting fuse (63 V rating, 63V@50A interrupting rating, typical cold resistance 0.071 ohm); non-polarized, interchangeable with the other terminal.

CAD (KiCad official)

  • Symbol: 0603FA-2HF
  • Footprint: Fuse:Fuse_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: 0603fa-2hf-etched.step / 0603fa-2hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 0603fa-2hf.step / 0603fa-2hf.glb are the bare package body.

Provenance
