High Power Precision Current Sense

The CS5 is a high power precision cur­rent sensing resistor designed with four
terminals. This resistor series is distin­guished 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.
