CZDYUF 18A High Frequency AC Power Filter EMI Filter Module for Speaker Audio Amplifier Home Theater

This filter module is designed to suppress electromagnetic interference (EMI) in high frequency power supply applications like home theaters and audio amplifiers. It uses three filtering techniques to reduce interference noise:

• Add a capacitor between the live and neutral wires of the power supply, known as the X capacitor. The X2 type is selected for this module to eliminate common mode interference, with a capacity range of 0.01UF—0.47UF
• Add a capacitor between the power line and the ground, known as the Y capacitor. The Y2 type is selected to eliminate crosstalk interference, with a capacity range of 2200pF ~ 0.1μF
• Common mode rejection by using a common mode inductance, also known as a suppression coil, on the two power lines. The circuit uses a 10MH inductance to improve the low-frequency attenuation characteristics.

The filter module comes with an 18A high current common mode inductor and a PCB size of 95X28X1.6MM. The input GND needs to be connected to the ground of the power cord and can be connected to the chassis.

This module can help improve the performance of electronic devices by reducing interference and providing a cleaner power supply. It is a valuable DIY component for electronic enthusiasts.
