WSLP3921 and WSLP5931 High Power Resistors

Vishay / Dale WSLP3921 and WSLP5931 High Power Resistors are very high power (to 15W) with low resistance values (down to 0.0001Ω). These surface mount, Power Metal Strip® resistors feature an all-welded construction, making them ideal for all manners of current sensing, voltage division, and pulse applications. Available in 3921 and 5931 case sizes, the AEC-Q200 qualified Vishay / Dale WSLP3921 and WSLP5931 High Power Resistors cover low inductance range of 0.5nH to 5nH.
