AEC-Compliant SMD Molded High-Current Shunts

Stackpole's new 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 200ppm TCR and 10, 15, and 20 milliohm values in 75ppm TCR.

The molded package and larger terminations provide exceptional thermal resistance and allows the part to run cooler at higher power levels than typical chip resistors of this size.

Applications are expected to include: power modules, frequency converters, inverter controls, power management, current sensor for power hybrid sources, and similar uses.

In addition, the HCSM is rated for full power operation up to 100ºC and allows derated operation up to 170ºC. 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.

The HCSM2818 10, 15, and 20 milliohm values are in stock. Pricing for the HCSM depends on tolerance and ranges from $0.40 to $0.45 each in full package quantities. Contact Stackpole or a franchised distributor partners for volume pricing.
