CS5 Series
High Power Precision Current Sense
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.
