Stackpole releases HCSM2818 high current shunt chip resistors with a 5W power rating.
Modern electronics utilize current sense resistors for portable power management. As more devices become portable, higher currents and higher power ratings are critical, however, space for any portable electrical device must always be conserved.
The HCSM2818 from Stackpole is only marginally larger than a standard 2512 size chip but offers a 5 watt continuous power rating to maximize power handling in a given PCB area.
The AEC compliant HCSM2818 offers 1% and 5% resistance tolerances in resistance values of 4, 5, 10, 15, 20, and 25 milliohms. TCR ranges from 200 ppm for the 4 and 5 milliohm values to 75 ppm for the values 10milliohmsand higher.
Pricing for the HCSM2818 varies with tolerance and ranges from $0.40 each for 5% to $0.45 for 1% tolerances.
