High Energy Corporation SPFT Series Feed-Thru capacitors are carefully designed, hollow ceramic tubes used to communicate power and low frequency signals between high-power RF chassis and other RF-radiating elements. These capacitors provide an elegantly simple means of bypassing massive amounts of RF energy to ground to maintain system signal integrity. They are built upon high quality Class I dielectrics, assuring a low dissipation factor and high bandwidth. SPFT feed-thru capacitors find application in RF heating, power transmitters and high voltage filters.
