The CS5 is a high power precision cur-

rent sensing resistor designed with four

terminals. This resistor series is distin-

guished by excellent long term stability

& TCR. The Kelvin connections allow

high precision measurements even with

low resistance values. The CS5 series

has a non-inductive copper manganin

element inserted into a cement sealed

ceramic case.
