Power EMI Filter Module—PFM1209 Series

Overview

Power circuit is the route of transmission of EMI noise. EMI noise affects the operation of the electronic device by the power circuit and EMI noise come from electronic device affects other device by the power circuit.

Background

Power EMI filter is a passive low-pass filter consists of both capacitors and inductors, it can suppresses the EMI noise come from power circuit and electronic device, to protect electronic device from EMI noise. Power EMI filter is a Indispensable component for electronic system to meet the Electro Magnetic Compatibility standard.

Features

  • Smaller, larger current tolerance
  • High suppression ability in a wide frequency band
  • Excellent solderability and high heat resistance

Applications

  • Hi-Fi 
  • Automotive 
  • DC power supply
