A is classified by working frequency: Power frequency transformer: working frequency is 50Hz or 60Hz IF transformer: operating frequency is 400Hz or 1KHz Audio transformer: operating frequency is 20Hz or 20KHz Super audio transformer: above 20KHz, no more than 100KHz High-frequency transformer: The operating frequency is usually above KHz to over 100 KHz. B is classified by purpose: Power transformer: a transformer used to supply the power required by electronic equipment Audio Transformer: Transformer for audio amplifier circuits and audio equipment Pulse transformer: A transformer that operates in a pulse circuit. The waveform is generally a unipolar rectangular pulse wave. Special transformer: Transformer with special function, such as parametric transformer, voltage regulator transformer, super isolation transformer, transmission line transformer, leakage transformer Switching power supply transformer: transformer used in switching power supply circuit Communication transformer: used for transformers in the communication network that are isolated and filtered Color Pvb Film,Vanceva Color Pvb Interlayers,Color Film Band,Color Pvb Film Car HUAKAI FENGSHI TECHNOLOGY (CHONGQING) CO., LTD. , https://www.cqhkpvb.com
