Vishay Intertechnology, Inc. introduces two low value, surface-mount Power Metal Strip resistors with power ratings of 3.0 W and 5.0 W and low resistance values down to 0.2 mΩ. The Vishay Dale WSL3921 and WSL5931 are suited for all types of current-sensing, voltage division, and pulse applications including switching and linear power supplies, instruments, and power amplifiers in automotive electronic controls; battery-charging systems and motor controls in consumer products; and motor controls in industrial systems. The WSL3921 resistor measures 0.394 inches× 0.205 inches [10.0 × 5.2 mm] with a maximum height profile of 0.071 inches [1.80 mm], and the WSL5931 resistor measures 0.591 inches× 0.305 inches [15.0 × 7.75 mm] with a height profile of 0.068 inches [1.73 mm]. A proprietary processing technique produces low resistance values ranging from 0.2 to 4.0 mΩ with tight tolerances of 1.0% and 5.0%. The WSL3921 and WSL5931 provide low inductance of 0.5 to 5 nH, good frequency response, and low thermal EMF.
