High Energy Corp. | Leaders in Oil-Filled and Cermic High Voltage Capacitor Technology
SPHT Series Ceramic Capacitors are Class 1 parts featuring High Voltage, Current and Power ratings and low self-inductance. A broad variety of these 'Power-Disk' capacitors are offered including the innovative and cost effective 'Ferris-Wheel' configuration. All SPHT capacitors have low dissipation factors. Their structure is both simple and robust, assuring a long trouble free life. SPHT Series feature a phenolic resin coating and a long flashover path. They are built upon a choice of eight Class I dielectrics, providing a broad range of capacitance and temperature coefficients. Uses include RF transmitter circuits, antenna couplings, and other high-power RF applications.
