Product Description: DC LC Filter EMI EMC Automotive Sound High Frequency Power Supply Filtering Board 4A Enhance your electronic systems with our advanced DC LC Filter EMI EMC Board, designed to deliver superior power supply filtering for automotive and high-frequency applications. This finished board is engineered to tackle electromagnetic interference and ensure clean, stable power delivery. Three-Stage Filtering Our filter board features a sophisticated three-stage filtering process. The first and third stages utilize LC filtering circuits, while the second stage employs common mode EM filtering. This comprehensive approach ensures optimal reduction of noise and interference. LC Filtering The LC filter is a passive filter, traditionally used for DC power supply harmonic compensation. Composed of inductors and capacitors, it effectively reduces unwanted harmonics, providing a cleaner power supply for your devices. Common Mode Filtering The EMI power filter board excels in filtering out harmonics from the power supply, whether they occur singly or in multiples. This common mode filtering purifies the DC power supply, enhancing the performance and reliability of your electronic systems. Suppression of Interference Designed to suppress fast transient group pulse interference, this DC EMI power filter is ideal for environments with high-frequency disturbances. It effectively handles interference with repetition frequencies of several kilohertz, ensuring stable operation. Wide Applicability The DC LC filter is versatile and can be applied to the output of switching power supplies. It is particularly effective in automotive and motorcycle applications where electromagnetic interference is prevalent, providing robust protection for DC circuits. Input and Output Ports The power supply filtering board is equipped with convenient input and output ports. The input port features IN+ and IN‑ terminals (two-wire 7.62 terminal input), while the output port includes output + and output ‑ terminals (two-wire 7.62 terminal output), ensuring easy integration into your systems. Upgrade your power supply systems with our DC LC Filter EMI EMC Board, designed for high performance and reliability in demanding environments. Whether for automotive applications or high-frequency electronic systems, this board ensures clean, interference-free power delivery.
