The Dale WSK1216 surface-mount Power Metal Strip current sense resistor provides a power rating of 3W in a 1216 case size. The component features a Kelvin 4-terminal connection with a resistance of 1 mΩ. Providing a power density of 260 W/in², the WSK1216 allows designers to save board space in high-power circuits by utilizing the smallest resistor possible. The device's 4-terminal connection enables higher accuracy and a reduction in system errors compared with a 2-terminal device due to decreased temperature dependency. Samples and production quantities of the WSK1216 are available now, with a lead time of six to eight weeks for larger orders. Pricing starts at $0.15 each/10,000.
