Vishay Intertechnology Power Metal Strip Resistor Delivers Power to 5 W in Compact 1206 Case Size

Vishay Intertechnology, Inc. introduced a new surfacemount Power Metal Strip current sense resistor that combines a high power rating up to 5W, TCR down to ± 75ppm/°C, and extremely low resistance values down to 0.3mΩ in the compact 1206 case size.

With power ratings 20 times higher than standard resistors in the 1206 footprint, the Vishay Dale WSLF1206 provides a power density of >650W/in², allowing designers to save board space in high power circuits by utilizing the smallest resistor possible without the need to parallel resistance elements. The device’s low TCR provides stable and accurate current measurement across a wide temperature range from -65°C to +170°C, while its low resistance values minimize power losses and improve end product efficiency.
