PURPOSE: An electromagnetic compatibility filter of a burial type outlet is provided to realize a maximum inductance value by ferrite beads and restrain generation of parasitic capacitance between leading wires. CONSTITUTION: If a plug is connected to electronic/electric/electronic communication equipments, a current is provided to the electronic/electric/electronic communication equipments through a hot line(30), a neutral line(31), and a ground line(32) of an EMC(ElectroMagnetic Compatibility) filter. A magnetic field is formed between the hot line and the neutral line as harmful electronic waves. In the case that the current flowing in the hot line and the neutral line passes through ferrite beads(34,36) acting as inductors, a direction of the magnetic field is changed to offset the electronic waves. A value of a parasitic capacitor between the hot line and the neutral line becomes '0' by removing a dielectric substance. |
