**VISHAY(威世)** · Current Sense Resistors / Shunt Resistors · 1206

WSLP1206R0200FEA from VISHAY(威世), 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 | 1 | passive | First terminal of the 2-terminal WSLP1206 current-sense resistor; the datasheet drawing shows two solder-pad terminals (pad a 0.062 in/1.57 mm, b 0.070 in/1.78 mm, l 0.030 in/0.76 mm) with optional sensing traces, and 1 W rated at 70 °C. |
| 2 | 2 | passive | Second terminal of the 2-terminal WSLP1206 current-sense resistor; the part is non-polarized and not voltage or ESD sensitive, with operating temperature -65 to +170 °C. |
