UHV Ultra-High-Voltage Ceramic Capacitors

TDK UHV Ultra-High Voltage Ceramic Capacitors feature a rated voltage range of 20kV to 50kV, low ESR, low loss, and a low distortion factor. These capacitors use molded-type metal screw terminals for easy mounting as well as a high-reliability mold resin. TDK UHV Ultra-High Voltage Ceramic Capacitors are designed for high voltage power supplies/lasers. Typical applications include high-voltage power circuits, medical devices, lithography, and industrial analyzers.
