.The CSM025AY-100 with Current Sensors Through Hole RoHS manufactured by Chahua-Electric is a current-sensing electronic device, specifically a transimpedance amplifier. This part is used to determine the current of the power line. It contains an internal circuit that generates an output voltage that is proportional to the sensed current with an instantaneous full scale ranging from 2.5 mA to 40 A in AC and DC applications. The part is encased in a small RoHS compliant, through-hole package with a mounting hole that enables easy handling and installation. It has a wide voltage input range of 4.75V—30V, an operating temperature range from -40°C to 85°C, and an accuracy of ±1%. Additionally, it is RoHS compliant, making it suitable for use in areas where RoHS is required.
