2 RF Power Capacitors Class 5kV Discs The CeramTec Group is a world leader in the design and manufacture of complex electronic ceramic components and assemblies used in a wide range of applications and cutting edge technologies. CeramTec UK specialises in the development and production of dielectric and ferroelectric materials and components. This range of high voltage RF discs capacitors is fabricated from very low loss CLASS ceramic dielectric materials which permit them to carry very high electrical loads over a wide frequency range. APPLCATONS NCLUDE Radio Broadcast Transmitters nduction and Dielectric Heating Equipment HF Filter, By-Pass & Coupling Circuits High Power Matching Tuned Circuits Antenna Circuits ndustrial Applications High Power matching networks Plasma Generators High quality medical imaging systems (MR) FEATURES Low loss Class ceramic dielectric materials with noble metal electrodes resulting in low self heating. High Voltage / High Reactive Power s Very low NPO capacitance-temperature characteristics available that result in correspondingly low tuned frequency drift. Low nductance construction permitting higher frequency use.
