Würth Elektronik's thick film resistors are available in three different product series. First is the WRIS-KSKE series, composed of general-purpose current sensing thick film resistors with a rated power range of 0.125 W to 1 W. Next, the WRIS-KWKB series offers thick film resistors with high-power current sensing (maximum of 2 W). Lastly, the WRIS-KWKH series offer a maximum power rating of 1 W. All of these thick film resistors feature current detection of small current levels and low- to mid-level resistance values.
