1. Transformer method

The input voltage and output voltage are changed by the winding ratio of the three-pin inductor to achieve the effect of voltage transformation and isolation.

2. Filtering method

The three-pin inductor can play a certain filtering role in the circuit, so that the signal is isolated and weakened when passing through.

3. Weak current signal processing

The three-pin inductor has a good performance in some weak current signal processing circuits, which can play the role of isolation, amplification, and voltage stabilization, making the signal transmission more stable.

Application of three-pin inductor: used in lamps and automotive products. High efficiency, low temperature rise, alarm boost, LED lighting, smoke alarm, doorbell, welcome sensor, anti-lost device, smart lock alarm inductor, atomizer, aromatherapy machine, humidifier, etc. Meisongbei Electronics also can supply SMD type 3 pins inductors.
