The Two-stage Composite High-Frequency EMI DC Filter, also known as an AC EMI power filter, is designed to mitigate electromagnetic interference (EMI) in single-phase AC power systems ranging from 110V to 250V. It features a two-part circuit configuration: an RFI DC blocking circuit and a two-stage composite EMI filtering circuit. The RFI DC blocking circuit eliminates AC interference caused by DC components from household appliances, enhancing power quality and preventing transformer saturation. The two-stage EMI filter effectively suppresses high-frequency noise, improving the performance of connected devices such as decoders and power amplifiers. Specifications of Two-stage Composite High-Frequency EMI DC Filter Input Voltage: Single-phase AC 110-250V Load Rated Current: 4A Input Port: Three-wire input Output Port: Three-wire output Dimensions: 38x100x1.6mm PCB Specification: FR4 Effective Filtering: Two-stage composite EMI EMI filter Applications: Decoder, power amplifier Features: RFI DC blocking, high-frequency noise suppression Installation: Connect GND input to power line ground wire How to Use the Two-stage Composite High-Frequency EMI DC Filter The Two-stage Composite High-Frequency EMI DC Filter should be installed in the power supply line to filter out DC components and high-frequency noise. Ensure proper orientation during installation, particularly when soldering the 4A common mode inductor, following the labels and instructions provided on the circuit board.
