Bourns Announces High Power Shunt Resistors with Metal Sensing Pins for Accurate Measurement in High Current Applications

New shunt resistors provide high reliability, cost-effective solution for battery management systems, high current industrial controls and electric vehicle charging stations

RIVERSIDE, Calif., October 10, 2022 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced an extension to its Model CSM2F Series power shunt resistor portfolio with 12 new series. These new series feature riveted through-hole metal sensing pins meeting the growing need for accurate positioning of voltage sense points in high current applications. These latest additions to the Bourns® Model CSM2F Series shunt resistor family are engineered using the Company's electron beam-welded resistive technology that supports high power designs up to 50 watts with continuous current up to 1414 amps. In addition, these new series are constructed with a metal alloy resistive element that delivers a thermal EMF as low as 0.25 µV/K.

Available in two or three tin-plated copper pin options, the new Model CSM2F Series with additional sensing pins offers a third pin option that is connected to the ground side of the circuit. The three-pin design helps reduce sensing errors by carrying the ground current on a separate path from the sensing circuit for higher measurement accuracy. The new Bourns® Model CSM2F Series shunt resistor family extension also features a wide resistance range from 25 µΩ up to 200 µΩ, and a low ±50 PPM/°C TCR in the 20 °C to 60 °C temperature range. Giving designers additional flexibility, the new series are offered in three different surface finishes to match various customer environmental and soldering needs, and are available in four package sizes: 6918, 8518, 7036 and 8536 (metric).

All series of the Bourns® Model CSM2F high power shunt resistors are available now and are RoHS compliant* and halogen free**. For more detailed product series information, please see: www.bourns.com/products/resistors/current-sense-resistors

*RoHS Directive 2015/863, Mar 31, 2015 and Annex.

**Bourns considers a product to be "halogen free" if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
