10-mohms to 50-mohms, 0.5W, current-sensor resistor for DC/DC converters

Vishay has released the WSLP0805, a surface-mount power metal strip resistor that is the industry's first 0.5-W current sensing resistor in the compact 0805 package size. This resistor is suggested for current sensing applications in dc-to-dc converters for computers, VRMs for laptops, and Li-Ion battery safety and management; and electronic automotive systems, including engine controls, multi-media electronics, climate controls, and anti-lock brakes. The WSLP0805 resistor features a 10-mohms to 50-mohms resistance value range, and high-temperature performance up to +170°C.

The WSLP0805 resistor allows it to replace larger current sensing resistors, saving space on the circuit board that in turn will create smaller and lighter products for the consumer.

The WSLP0805 features an all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element. The resistor offers inductance values from 0.5 nH to 5 nH, a frequency response to 50 MHz, and thermal EMF of less than 3 µV/°C.
