Bourns offers metal strip chip resistors and electro-beam welded metal strip shunts. These high-power resistors have very low resistance values and TCR due to their metal strip resistive element and are suitable for all types of current sensing applications. Metal strip chip resistors (Model CRA, CRE, CRF, CST Series) have electroplated tin (Sn) outer terminations for soldering onto the board. The resistive element is protected by an epoxy overcoat layer. EB welded metal strip shunts (Bourns® Model CSS Series) are manufactured using an electron beam-welded metal strip with an iron chrome or manganese copper alloy resistive element, providing excellent electrical characteristics. They also feature copper alloy terminations that deliver additional mechanical strength and enable ease of solderability. Very high power
