Description

EI4835 pin low frequency transformer

Low frequency transformers are used to transmit signal voltage and signal power,Impedance matching between circuits can also be achieved,Isolates DC current。It is divided into interstage coupling transformer、Input transformer and output transformer integrated inductor,wire inductance,,The appearance is similar to that of a power transformer。

1. Inter-pole coupling transformer Inter-stage coupling transformer is used in two-stage sound integrated inductor,wire inductance,Inductor manufacturer,Shenzhen inductor,Electronic news frequency amplifier circuit between,as coupling element,Send the output signal of the preamplifier circuit to the subsequent stage,And make appropriate impedance transformation。

2. Input transformer in early semiconductor radios,Audio integrated inductor,wire inductance,Inductor manufacturer,Shenzhen inductor,The transformer used between the electronic press push stage and the power amplifier stage is the input transformer,signal coupling、Transmission,Also known as push transformer。The input transformer has single-ended input type and push-pull input type.。If the push circuit is a single-ended circuit,Then the input transformer is also a single-ended input transformer;If the push circuit is a push-pull circuit,Then 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.,Mainly plays the role of signal transmission and impedance matching。
