Features:

High-Quality Materials: The 4A 10A 20A EMI Power Filter Board is constructed from premium components, ensuring guaranteed quality and stable performance. Whether the product is purchased as a finished board or in loose parts for DIY assembly, the materials used are designed to achieve optimal functionality and longevity.

Perfect for DIY Enthusiasts: This EMI filter board caters to DIY enthusiasts by offering both finished boards and do-it-yourself loose parts kits. It provides a practical project for individuals looking to enhance their skills in electronics assembly. The simple and convenient operation makes it accessible, even for beginners, making it a valuable educational tool.

Effective EMI Filtering: Designed as a three-stage EMI filter for audio power amplifiers, it significantly reduces electromagnetic interference when used in tandem with decoders or power amplifiers. It effectively filters out DC components and suppresses transformer hum and high-frequency noise, thereby purifying the power supply. This improves the sound quality of the amplifier, enhancing resolution and providing a quieter background.

Advanced Filtering Design: The module features a sophisticated three-stage design comprising a differential mode and two common mode stages. This setup ensures superior noise filtering capabilities, efficiently suppressing transient fast group pulse interference with a repetition frequency of several thousand hertz. This high-level filtering enhances the overall audio output quality.

Easy Integration: The EMI filter board comes with clear, easy-to-connect input and output terminals (7.62 three-wire input socket and 7.62 two-wire output socket). The input GND should be connected to the power cord's ground wire and can also be connected to the chassis, depending on specific requirements. This ensures safe and efficient installation and operation.
