Ohmite CS3FR050E Four Terminal Precision Current Sense

The OHMITE CS3 Series represents a cutting-edge solution for current monitoring and control. These four-terminal precision current sense resistors are engineered for highly reliable, non-inductive performance, making them suitable for a wide range of industrial applications. The CS3FR050E, in particular, features a polyester encapsulation over the resistance element and utilizes Kelvin terminals with a 97% Sn / 3% Ag solder over copper construction. With resistance values ranging from 1 milliohm to 50 milliohm and tolerances of 1%, 2%, and 5%, the CS3 series provides flexibility for diverse circuit designs. Its robust design, operating temperature range of -55°C to 150°C, and power rating of 3W at 70°C, ensure reliable performance in demanding environments.
