SING F LTD 8Pcs EI14 Audio Coupling Isolation Transformer 600600 Ohms 11 4 Pin High Efficiency Audio Isolation Transformers for Microphone Sound Amplification

This is a special transformer mainly used for the transmission and isolation of audio signals. Not only can it pass audio signals, it can also reduce interference from electrical noise through its isolation feature, thereby improving audio quality., The transformer has four pins, which are usually used to connect the positive and negative terminals of the input and output. This design allows the transformer to be easily connected to audio equipment., 600:600 ohm 1:1 audio isolation transformer can be used in radio communications, radio and television, automatic control and other fields as voltage amplification, power output and other components., The primary and secondary windings are tightly coupled and have sufficient passband. The primary winding has large inductance and small leakage inductance, which can reduce the impact of hysteresis loss.
