CS5 Series
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.
