**BOURNS** · Disposable Fuses · 0603

SF-0603SA150M-2 from BOURNS, in a 0603. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Fuse terminal 1. Non-polar SMD chip fuse end cap; carries the protected line current up to 1.5 A rated. Typical terminal resistance ~0.116 Ω (both ends combined, ±25 %). |
| 2 | 2 | passive | Fuse terminal 2. Non-polar SMD chip fuse end cap; carries the protected line current up to 1.5 A rated. Interrupts at 50 A at 65 VDC when the fuse element clears. |
