4-Pin Micro Current Transformer

4-Pin Micro Current Transformer

There are 4 pins at the bottom of the tiny size current transformer (CT), which make it can be properly assembled and soldered. The coil of 2000 turns, made by fine enamel wires, is filled by epoxy resin and connected to 2 pins, while the other 2 pins are used for positioning.
