WSR5 Power Metal Strip® Resistors

Vishay / Dale has expanded the WSR Series Power Metal Strip® Resistors. The WSR5 resistors are high power (5 W), low value (down to 0.001Ω), surface mount resistors that are ideal for all types of current sensing, voltage division, and pulse applications including switching and linear power supplies, instruments, and power amplifiers. The integral heat sink is not utilized for resistance values less than 0.0075Ω. The WSR5 series is available in 4527 EIA case size with a small footprint of L .455", W .275", H .095. Improved thermal management is incorporated into the all-welded, molded high temperature encapsulation, Lead-free construction of solid metal Nickel-Chrome or Manganese-Copper alloy resistive element with low TCR (<20 ppm/ºC). The Vishay / Dale WSR5 Power Metal Strip Resistors feature very low inductance (<5 nH), low thermal EMF (<3 µV/ºC), and excellent frequency response to 50 MHz. Compliant to RoHS directive 2002/95/EC.
