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. 

Introduced by Stackpole Electronics their CSSK3637, a four-terminal surface mount shunt, claims to offer 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, potentially ensuring outstanding electrical and environmental stability across a diverse array of end products.

They do on to claim that the  3-watt rated CSSK3637 is fully compliant with RoHS standards, being lead-free, REACH compliant, and halogen-free.
