It has been announced that Stackpole's new HCSM2818 is a 5W surface mount part with an all-metal element and moulded construction. The HCSM2818 is available in resistance values of four, five, ten, 15, and 20mΩ in one and five percent tolerances. TCR is 200 ppm for the values below ten milliohm and 75ppm for values of ten milliohm and above.

With full power operation up to 100°C and operating temperature limit of 170°C, the HCSM is well suited for high power current sensing which normally experiences significant self-heating. The large terminations provide a thermally efficient connection which helps reduce the convection and conduction cooling.

The HCSM2812 is RoHS compliant, Halogen and lead free.

Pricing for the HCSM2818 is $0.38 each in full reel quantities.
