Vishay said the small resistor will allow designers to save space on the circuit board and to design smaller and lighter consumer products. The resistor is targeted at computer DC/DC converters, VRMs for laptops, Li-ion battery safety and management products, and electronic automotive systems such as engine controls, multimedia electronics, climate controls, and anti-lock brakes.

The WSLP0805 has an all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element. The inductance values range from 0.5nH to 5nH while the frequency response is 50MHz and thermal EMF is below 3µV per �C.
