The Vishay WSR3 series are surface mount, power metal strip resistors. The WSR3 series have a low resistance values ranging from 1mohm to 0.2ohm and power rating of 3W. These resistors use solid metal nickel chrome or manganese copper alloy as a resistive element with low TCR. The WSR3 series are ideal for all types of current sensing, voltage division and pulse applications.
