Low frequency transformer is used to transmit signal voltage and signal power, and can also realize impedance matching between circuits, which has isolation effect on DC. There is no difference in principle between high frequency transformer and low frequency transformer. However, due to the different frequencies of high frequency and low frequency, the iron cores used by Transformers are different. Low-frequency transformers generally use silicon steel sheets with high magnetic conductivity, while high-frequency transformers use high-frequency ferrite cores."

2.Application:

This product is made of high temperature flame-retardant bakelite skeleton, high quality lacquered copper wire, three layers of insulated wire and high flux density of ferrite core.
