Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a noise filter of a high-frequency generator adjusting the intervals of winding of a core type inductor to maximize a noise attenuation band. SOLUTION: This noise filter comprises a choke coil with a first winding part wound at a first interval, a second winding part wound at a second interval, and a third winding part wound at a first interval connected in mutual series, and a high-frequency energy absorbing member inserted into the choke coil. The high-frequency energy absorbing member is selected from a group comprising an iron oxide, tin alloy, and ferrite. The high-frequency energy absorbing member has a cross-sectional area for attenuating noise in the 30 to 1,000 MHz band. COPYRIGHT: (C)2004,JPO&NCIPI |
