Product information "HT57 Series Ceramic Capacitors"
10 pF to 500 pF; VMAX 15 kV; SMAX 35 kVA
HT Series Ceramic Capacitors are small, RF-capable, Class 1 parts featuring high Voltage, Current and Power ratings. They exhibit a low dissipation factor and minimum self-inductance. These extremely rugged capacitors are carefully designed to live in the demanding world of broadcast and high-voltage industrial application. Their structure is both simple and robust, assuring a long trouble free life. HT Series parts feature a nonconductive, humidity-resistant, coating and a long flashover path. They are built upon a choice ofsix Class I dielectrics, providing a broad range of capacitance and temperature coefficients. Typical applications include transmitters, antennas, induction heating, X-ray, diathermy and welding.
