Littelfuse CH1P050N Current Sensors

Littelfuse CH1P050N Current Sensors are designed to measure AC, DC, or pulsed currents with galvanic separation between primary and secondary circuits. The Open Loop Hall effect current sensors offer high immunity to external interference and low insertion loss. The Littelfuse CH1P050N Current Sensors provide easy mounting via automated handling in a very small package size.
