CeramTec Ceramic Capacitors

CeramTec capacitor products cover two broad application areas: High Frequency / RF power and high voltage. Each of these product lines requires particular ceramic material formulations for optimal performance. 

The ceramic materials used for our ranges of RF & High voltage capacitors are compositionally varied to optimise their capability to support electrical fields and /or to act as insulators. We prepare our own dielectrics from raw materials at our Ruabon (UK) manufacturing site with Dielectric Constants from 6 to 5000 which allows us to design and manufacture capacitors from 5 to 10,000pF in voltage ranges from 5kV to 50 kV. 

In total we offer 19 formulations for class 1 and 2 dielectrics, mainly based on modified titanate compositions.
