**Sunway** · Current Sense Resistors/Shunt Resistors · 1206

SP1206FR005E1WPRH from Sunway, in a 1206. 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 | Terminal 1 | passive | One end termination (Cu/Ni/matte Tin) of the SP1206 metal-substrate current-sense resistor, 1W rated at 70°C, 3.20 x 1.60 mm body, with 0.60±0.20 mm termination length. |
| 2 | Terminal 2 | passive | Other end termination (Cu/Ni/matte Tin) of the SP1206 current-sense resistor; the two terminations are interchangeable, with rated power 1W and operating range -55°C to +170°C. |
