The WSLF2512 surface-mount Metal Strip current sense resistor combines a power rating up to 6W, TCR down to ± 70 ppm/°C, and low resistance values down to 0.0003 Ω in a 2512 case size. Providing a power density of 192 W/in.2, the device allows designers to save board space in high-power circuits. The device's low TCR provides stable and accurate current measurement across a wide temperature range, while its low resistance values minimize power losses and improve end product efficiency. A proprietary processing technique produces resistance values ranging from 0.0003 Ω to 0.003 Ω, with tolerances of ± 1% and ± 5%. The device provides low thermal EMF (< 3 μV/°C), very low inductance (< 2 nH), and a temperature range from -65°C to +170 °C. Pricing starts at $0.15/10,000.
