Low-frequency transformer manufacturers

Frequency transformers frequency transformer to pass pound signal voltage and signal power, but also to achieve impedance matching between circuits of DC with isolation effect. It is divided into inter-stage coupling transformer, input transformer and the output transformer integrally molded inductors, Rao line inductors, inductance factory, Shenzhen inductors, electronic news, shape are similar to the power transformer. 1. Pole transformer coupling between inter-stage coupling transformer after the two-tone with integrally molded inductors, Rao line inductors, inductance factory, Shenzhen inductors, electronic news between frequency amplifying circuit, a coupling element, the output signal of the preamp circuit is transmitted to the level, and to make appropriate impedance transformation. 2. Input transformer in the early transistor radios, the audio integrally molded inductors, used between Rao inductance inductance factory, Shenzhen inductors, electronic news promote stage and the power amplifier stage transformer input transformer, from the signal coupling, transmission effect, also known as To promote the transformer. Input transformer and push-pull type single-ended input input type. If the circuit is driven single-ended circuits the input transformer for single-ended input transformer; if the circuit is a push-pull circuit to promote, the input transformer input for push-pull transformer. 3. Connected between the output transformer output transformer and speaker power amplifier output circuit, mainly from the role of signal transmission and impedance matching.
