Stackpole CSSK3637 four terminal shunt chip resistors

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.
