**TA I Tech** · Disposable Fuses · 0603

CF06V5TR50 from TA I Tech, 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 (Sn-plated) of the fuse element; non-polarized, rated 0.50A, DC 50V, breaking capacity DC50V 50A, opens within 1 min at 200% rated current. |
| 2 | 2 | passive | Other end terminal (Sn-plated) of the fuse element; interchangeable with the first terminal, 290 mΩ typical resistance (±25%), body temperature rise <75℃ at 100% rated current. |
