Improved TCR in four terminal current sense shunt resistors

Current sensing resistors must balance the efficiency requirements of low resistance values and high current handling with the precision and accuracy requirements of the sensing circuit. But the key requirement of most current sensing circuits is stable performance over temperature. Component TCR is the key measurement parameter for the temperature stability of a resistor.

Stackpole Electronics recently improved the TCR for the CSSK0612 down to 100ppm for the full resistance range from 0.5milliohm to 5milliohm. This makes the all-metal device excellent for power monitoring, management, and control for a wide range of end products.
