Vishay / Dale WSBR Current Sense Resistors

Vishay / Dale WSBR Current Sense Resistors proprietary processing technique produces extremely low resistance values. These current resistors feature <5nH low inductance and low thermal EMF (low as <1.25μV/°C). The WSBR current sense resistors also feature dual elements for redundant current sensing and provide a high power-to-resistor size ratio. These SMD resistors are AEC-Q200 qualified, RoHS compliant, and halogen-free.
