WSL2512R0400FEA18 Current Sense Resistor | 40mΩ/2W | ±1% | 2512 Package | Vishay Automotive Grade

The WSL2512R0400FEA18 is an automotive-grade Power Metal Strip® current sense resistor from Vishay Dale, part of the WSL...18 high-power series with double the power rating of the standard WSL series. This device features a 2512 (6432 metric) package measuring 6.35mm × 3.18mm × 0.89mm, with a resistance of 40mΩ, power rating of 2W, tolerance of ±1%, temperature coefficient of ±75 ppm/°C, and an operating temperature range of -65°C to +170°C. Its all-welded metal element construction ensures extremely low inductance (0.5nH to 5nH) and low thermal EMF (<3µV/°C), along with anti-sulfur, moisture-resistant, and pulse-withstanding characteristics, specifically designed for high-precision current sensing applications. The product is AEC-Q200 qualified, making it ideal for automotive electronics, battery management systems, power management, and industrial controls requiring reliable current sensing.
