Vishay Intertechnology has introduced a surface-mount power metal strip resistor that has four terminals, and is a 1W current sensing resistor in the compact 0612 package size, offering a resistance range from 0.5 to 5mΩ.
The WSK0612 resistor is suitable for current sensing, voltage division, and pulse applications in DC/DC converters for computers, VRMs (voltage regulator modules) for laptops, Li-ion battery safety and management, and LCD TVs; and electronic automotive systems, including engine controls, multi-media electronics, climate controls, and anti-lock brakes.
The resistor features a durable all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element with TCR of less than 20ppm/°C. The resistor is compliant to RoHS Directive 2002/95/EC, and is claimed to offer high-temperature performance to 170°C and low thermal EMF of less than 3μV/°C.
