Littelfuse — CSR Family Current-Sense Resistors

Littelfuse has announced the launch of new current-sense resistors which offer a more cost-effective solution for functions such as voltage monitoring, battery charging, and motor control, while also providing over-current protection.

The eight new resistors from Littelfuse are metal-foil, metal-strip, or metal-plate resistors optimized for measuring current. They offer a combination of high precision and low resistance. The various resistor families are available in a wide range of case sizes and resistance ratings.

Littelfuse offers its current-sense resistors as a more cost-effective option than other technologies such as Hall-effect sensors, current transformers, flux gate sensors for dc applications, and Rogowski coils for ac applications.
