Through-type capacitor and magnetron using same

摘要

A through-type capacitor capable of effectively preventing peeling of an insulation resin from a ceramic dielectric and providing an insulation case of the capacitor with heat resistance, tracking resistance, arc resistance to improve burning resistance of the case, resulting in safely and positively operating for a long period of time. The capacitor includes an insulation case arranged to surround a ceramic dielectric and filled with insulation resin materials to embed the ceramic dielectric in the materials. The insulation case includes a first insulation case member formed of thermoplastic resin and arranged to surround the ceramic dielectric and a second insulation case member formed of thermosetting resin and integrally mounted on the first insulation case member.
