Vishay Intertechnology, Inc., has introduced a new surface-mount Power Metal Strip® resistor that is the industry's first 4-terminal, 1 W current sensing resistor in the compact 0612 package size to offer a very low resistance range from 0.5 mΩ to 5 mΩ.
The small size of the WSK0612 resistor allows it to replace larger current sensing resistors, saving space on the circuit board that in turn will enable creation of smaller and lighter products for the consumer. The WSK0612 is intended for current sensing, voltage division, and pulse applications in DC/DC converters for computers, VRMs 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.

Manufactured using proprietary techniques that result in extremely low resistance values, the WSK0612 features a durable all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 ppm/°C). Compliant to RoHS Directive 2002/95/EC, the resistor offers high-temperature performance to + 170 °C and low thermal EMF of < 3 μV/°C.
