Stackpole has announced its CSSK3637 four terminal shunt chip resistors for high-efficiency applications.

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

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

The 3-watt rated CSSK3637 is fully compliant with RoHS standards, being lead-free, REACH compliant, and halogen-free.

Pricing for the CSSK3637 varies based on tolerance, with approximate costs averaging around $0.50 each for 1% tolerances. For volume pricing, interested parties are encouraged to contact Stackpole or one of our franchised distributor partners. Currently, values ranging from 0.5 milliohm up to 5 milliohm are readily available in stock.
