Bourns high power current sense resistor series
Summary
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 four-terminal devices, in footprint size 4026, allow for very precise four-wire Kelvin (K) resistance measurement.
