**SART Nanjing Sart Tech** · Disposable Fuses · 0603

S0603-S-1.5A from SART Nanjing Sart 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 silver/tin-plated end termination of the 1.5A slow-blow fuse (32V DC, 50A/32V DC interrupting rating, max cold DCR 0.104 Ω); the fuse is non-polarized. |
| 2 | 2 | passive | Other silver/tin-plated end termination of the 1.5A slow-blow fuse (32V DC, 50A/32V DC interrupting rating, max cold DCR 0.104 Ω); the fuse is non-polarized. |
