Vishay WFK Metal Foil Current Sense Resistors employ a 4-terminal design and feature a 1mΩ to 10mΩ ultra-low sensing resistance range. These resistors offer low Temperature Coefficient of Resistance (TCR) down to 100ppm/°C. The WFK current sense resistors are Sulfur-resistant and are available in 0612 package sizes with a 1W power rating and ±1% tolerance. These metal foil current sense resistors operate within the -55°C to 170°C temperature range. The WFK current sense resistors are ideal for switching power supplies, voltage regulation modules, DC/DC converters, adaptors, battery packs, chargers, cell phones, and power management.
