EI4835 pin low frequency transformer

Low-frequency transformers are used to transmit signal voltage and signal power, and can also achieve impedance matching between circuits, and have an isolation effect on direct current. It is divided into an inter-stage coupling transformer, an input transformer and an output transformer integrated inductance, and a wire inductance. The shape is similar to that of a power transformer.　　

1. Inter-pole coupling transformer Inter-stage coupling transformer is used between two-stage audio integrated inductors, wire inductors, inductor manufacturers, Shenzhen inductors, electronic news frequency amplifier circuits, as a coupling element, to transmit the output signal of the previous amplifier circuit to the rear One level, and make appropriate impedance transformation.　　

2. Input transformer In the early semiconductor radios, audio integrated inductors, wire inductors, inductor manufacturers, Shenzhen inductors, electronic news promotion stage and power amplifier stage used transformers are input transformers, which play the role of signal coupling and transmission, also called To drive the transformer. The input transformer has single-ended input and push-pull input. If the pushing circuit is a single-ended circuit, the input transformer is also a single-ended input transformer; if the pushing circuit is a push-pull circuit, the input transformer is also a push-pull input transformer.　　

3. Output transformer The output transformer is connected between the output circuit of the power amplifier and the speaker, and mainly plays a role in signal transmission and impedance matching.
