EMI Filter Module Board, EMI High Frequency Two-Stage Power Supply Filter Module EMI Electromagnetic Interference Filter Module for Amplifier Module
  • 1>.High frequency electromagnetic interference (EMI) allows power filtering.In practice,two or even multiple technologies are often used in combination.
  • 2>.Add a capacitor between the live and neutral wires of the power supply is the X capacitor,X2 type is selected,the main function is to eliminate common mode interference,and the capacity range is 0.01uF-0.47uF.
  • 3>.Add a capacitor the power line and the ground is the Y capacitor.The Y2 type is selected to mainly eliminate crosstalk interference,and the capacity range is 2200pF~0.1uF.In order to reduce the leakage current,the capacitance should not exceed 0.1uF.This circuit board uses 3300pF.
  • 4>.Common-mode suppression,common-mode inductance (suppression coils on two power lines).When the rated current is large,the diameter of the common-mode choke coil should also be increased accordingly so that it can withstand large currents.In addition,appropriately increasing the inductance can improve the low-frequency attenuation characteristics.This line uses 10MH.
