Würth Elektronik Fixed Thick Film & Metal Plate Resistors

Würth Elektronik Fixed Thick Film and Metal Plate Resistors offer enhanced current, high power current, and general-purpose current sensing. The WRIS-KSKE, WRIS-KWKB, and KWKH thick film resistor series offer up to a 620Ω resistance rating, a 0.1 to 2W rated power range, and reflow soldering. WRIS-PSMB and WRIS-PSMC metal plate resistors offer up to a 10mΩ resistance rating, a 0.3 to 2W rated power range, and a ±5% maximum resistance tolerance. Würth Elektronik Fixed Thick Film and Metal Plate Resistors operate over a -55°C to +155°C temperature range.
