10A EMI Electromagnetic Interference Power Filter Filtering Pulse Surge Lightning Protection Common Mode The pulse surge lightning and overvoltage protection circuit adopts lightning discharge diodes and TVS transient voltage suppression diodes, providing multiple protections to effectively prevent damage to equipment caused by surges, high voltage, lightning strikes, etc. Three sets of common-mode filter, through the X2 capacitors and common mode inductor, combined into the common mode filter. Due to it is use of three stages filtering, so the filtering effect is more better. In view of the problem of rapid transient group pulse interference with repetition rate of several kilohertz in some users, it can play an inhibitory role. Notice: This filter filters high-frequency interference components in the AC power supply, preventing interference from the power grid from entering electrical equipment, and also preventing interference from equipment from entering the power grid and interfering with other electrical equipment. Used in power amplifiers and speakers, it can only improve the quality of the power supply and cannot solve the problem of current noise.
