WK73R Wide Terminal Resistors

KOA Speer Electronics' flat chip resistors are ideal for high-power applications

Image of WK73R Wide Terminal ResistorsKOA Speer Electronics' WK73R wide terminal resistors have superior thermal shock characteristics and high solder joint reliability. The resistance range of the WK73R resistors is 10 Ω to 1 MΩ, and the temperature coefficient of resistance (TCR) is ±100 ppm/°C and ±200 ppm/°C. The available tolerances are +0.5%, ±1%, and ±5% with a high-power rating of 0.33 W, 0.5 W, 1 W, and 2 W @ 70°C. These wide terminal flat chip resistors sizes include 0204, 0306, 0508, 0612, 1020, 1218, and 1225 and are AEC-Q200 qualified and RoHS compliant.
