4 Terminal Surface-Mount Power Metal Strip® Resistor (WSK0612 Series) | Vishay

Manufactured using proprietary techniques that result in extremely low resistance values, the WSK0612 is the industry's first 4-terminal, 1 W current sensing resistor in the compact 0612 package size to offer a resistance range from 0.5 to 5 milliohms. The small size of the WSK0612 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 features a durable all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (less than 20 ppm/°C). RoHS-compliant, the resistor offers high-temperature performance to + 170 °C and low thermal EMF of less than 3 microvolts/°C.
