Four terminal shunt chip resistors deliver for high-efficiency applications

Applications requiring high-efficiency current sensing, such as avionics, communications and infrastructure, tablets, and graphics drivers, generally demand extremely low resistance values. Nonetheless, ensuring sensing accuracy poses a formidable challenge due to lead resistance effects at such low levels. Four-terminal shunt resistors effectively mitigate errors arising from lead resistance.

Stackpole Electronic’s CSSK3637, a four-terminal surface mount shunt, provides extremely low resistance values ranging from 0.5mOhm to 6mOhm, with tolerances as low as 0.5% and a TCR of 50 ppm. Furthermore, this all-metal shunt delivers an operating temperature of up to 170C, ensuring exceptional electrical and environmental stability across a diverse array of end products.

The 3W-rated device is fully compliant with RoHS standards, being lead-free, REACH-compliant, and halogen-free.
