The HCSM2818 is a 5W surface mount current sense shunt with excellent long-term stability and good TCR. The HCSM offers 4 and 5 milliohm values in 200 ppm TCR and 10, 15, and 20 milliohm values in 75 ppm TCR. The molded package and larger terminations provide exceptional thermal resistance and allow the part to run cooler at higher power levels than typical chip resistors of this size.
In addition, the HCSM is rated for full power operation up to 100°C and allows derated operation up to 170°C. This high-temperature capability is important for high current power control and monitoring, such as for power modules and inverter control, frequency converters, and power management for hybrid vehicles.
