Abstract
A interference of outside electric source and electric fast transient(EFT) are origins of destroy and malfunction in the precise electrical and electronic equipments. It makes a serious obstacle as the form of conducted noise. Therefore, it is strongly needed to protect precision electrical and electronic equipments from the interference and EFT. In this research, a EMC filter composed of feed-through capacitors and ferrite beads of high permeability is designed and it＇s properties are investigated for PDP. The filter produced in this research have wide band frequency characteristics and more than 40 dB reflection loss in the frequence of 10 MHz∼1.5 GHz which satisfy the standard of CISPR Pub. 22 and the level 4 of IEC 61000-4-4.
