High-Quality Materials

The 4A 10A 20A EMI Power Filter Board is crafted from premium components, ensuring quality and stable performance. Whether you choose the finished board or loose parts for DIY assembly, the materials are designed for optimal functionality and longevity.

Perfect for DIY Enthusiasts

This EMI filter board is ideal for DIY enthusiasts, offering both finished boards and do-it-yourself loose parts kits. It’s a practical project for those keen to enhance their electronics assembly skills. The operation is simple and convenient, making it accessible for beginners and a valuable educational tool.

Effective EMI Filtering

As a three-stage EMI filter for audio power amplifiers, it substantially reduces electromagnetic interference when paired with decoders or power amplifiers. It efficiently filters out DC components and suppresses transformer hum and high-frequency noise, purifying the power supply and enhancing sound quality with improved resolution and a quieter background.

Advanced Filtering Design

The module boasts an advanced three-stage design with one differential mode and two common mode stages. This setup ensures superior noise filtering, effectively suppressing transient fast group pulse interference with a repetition frequency of several thousand hertz, enhancing overall audio output quality.

Easy Integration

The EMI filter board features 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 as per specific requirements, ensuring safe and efficient installation and operation.
