Rated up to 60A Current Sense Resistors offer Stability and Accuracy

Addressing both high board population limitations and low resistance value requirements, the new CS5 Series from Ohmite Manufacturing Co. goes on show for the first time during Electronica at the Ohmite booth in Hall B6 Stand 412. Designed for use in power modules, frequency converters and switch mode power supplies, Ohmite have used a 4-terminal Kelvin connection to provide ease of installation and eliminate stray TCR drift from the current-carrying terminals. This termination style also measures change in current more accurately than 2-terminal designs.

The resistance values of the CS5 are down to 0.001 ohms to enable higher current carrying capability up to 60 Amps and the 30ppm TCR-means great stability of the resistance value over time. Tight tolerance models of the CS5 will be stocked in both 1% and 0.50% tolerances.

Available in 0.001, 0.002, 0.003, and 0.004 ohm resistance values, the CS5 series uses a non-inductive copper manganin element inserted into a cement sealed ceramic base.
