ABSTRACT:
The present invention is directed to a high voltage capacitor and a magnetron which can reduce the weeping noise resulting from the electrostriction phenomenon while maintaining the function as a filter.
A capacitor constituted with a dielectric porcelain, is provided with through holes which pass through the dielectric porcelain and electrodes on the two surfaces where the through holes open. One of the electrodes is secured onto one surface of a grounding member. Through conductors are connected with electrical continuity to the electrodes by passing through the capacitor and the grounding member. Insulating resins are filled around the capacitor. The relative dielectric constant of the dielectric porcelain is within the range of 3000 to 6000.
