MALVERN, USA: Vishay Intertechnology Inc. announced a new surface-mount Power Metal Strip resistor that is the industry's first 0.5-W current sensing resistor in the compact 0805 package size.
The WSLP0805 resistor features a very low 10 to 50 milliohms resistance value range and high-temperature performance up to 170 deg. C.
The small size of the WSLP0805 resistor allows it to replace larger current sensing resistors, saving space on the circuit board that in turn will enable smaller and lighter products for the consumer.
The resistor is intended for current sensing applications in DC/DC converters for computers, VRMs for laptops, and Li-Ion battery safety and management, as well as electronic automotive systems, including engine controls, multi-media electronics, climate controls, and anti-lock brakes.
Manufactured using proprietary techniques that result in extremely high power and low resistance values, the WSLP0805 features all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element. The resistor offers very low inductance values from 0.5 nH to 5 nH, an excellent frequency response to 50 MHz, and low thermal EMF of less than 3 microvolts per degree Celsius.
Samples and production quantities of the new resistor are available now, with a lead time of four to six weeks for larger orders.
