# RLP25FEER150

**TA I Tech** · Current Sense Resistors / Shunt Resistors · 2512

RLP25FEER150 from TA I Tech, in a 2512. 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 Ni/Sn-plated terminal of the RLP25FEER150 metal-alloy current sense resistor (R150 = 150 mΩ, ±1%, 2 W rating, -55 to +170 °C operating range), with a recommended pad of a=4.0 mm, b=2.1 mm for R>0.004 Ω. |
| 2 | 2 | passive | The other Ni/Sn-plated terminal of the same resistor, electrically interchangeable with the first, with a Kelvin sensing trace taken from the inner edge of each pad as shown in the recommended solder pad drawing. |
