0435002.KRHF
Littelfuse · Disposable Fuses · 0402
0435002.KRHF from Littelfuse, 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 | Fuse terminal 1 (tin-plated end termination); the 2.0 A part is rated 32 V max with 35 A interrupting rating at 32 VDC, and the fuse is non-polarized so the terminals are interchangeable. |
| 2 | 2 | passive | Fuse terminal 2 (tin-plated end termination); the 2.0 A part has a nominal cold resistance of 0.03001 ohm and is non-polarized so the terminals are interchangeable. |
