Providing Accurate Current Measurement for Power Electronics, Bourns Introduces Four High Power Current Sense Resistor Series

Engineered to save energy and maximize sensing performance, the series' advanced construction design delivers high power, low resistance and low TCR

RIVERSIDE, Calif., December 4, 2023 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection and sensing solutions today introduced four high power, ultra-low ohmic current sense resistor series. The latest current measurement devices from Bourns are designed to help save energy while maximizing sensing performance in power electronics designs. The four CSI Model Series feature low Temperature Coefficient of Resistance (TCR) for operating accuracy over a wide temperature range and excellent long-term stability. Their very low resistance levels, low thermal electromagnetic force (EMF) and high power handling capabilities make them ideal solutions for a variety of industrial and consumer applications and power electronics including Battery Management Systems (BMS), Switched-Mode Power Supplies (SMPS) and motor drives.

Current sense resistors are increasingly being used in higher power applications due to their precise measurement accuracy and relatively low cost compared to other technologies. Bourns developed this new family to help designers meet the monitoring accuracy necessary to provide a current reading that assists in the efficient operation of the circuit.

Bourns' new Model CSI Series are constructed with Electron Beam Welded (EBW) resistive and copper alloy terminals, and are available in both two and four-terminal options. The two-terminal models are offered in three different footprint sizes: 5930, 3920 and 2512. The four-terminal devices, in footprint size 4026, allow for very precise four-wire Kelvin (K) resistance measurement. The metal alloy current sensing element supports low thermal EMF and low TCRs of ±50 PPM/°C in the 20 °C to 60 °C temperature range. All four models supply resistance values as low as 0.2 milliohms, and customers can select from a range of low resistance options and power ratings of up to 15 W.

All four Bourns® Model CSI Series high power, ultra-low ohmic current sense 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.
