Within the ceramic capacitor family there are many forms of ceramic dielectric that are used.

Glass dielectric capacitor. Common types include c0g np0 x7r y5v z5u although there are many more. Glass dielectric capacitors have been the capacitors of choice for extreme long term stability and reliability for almost fifty years. Glass dielectric capacitors offer very high levels of performance although their cost is high when compared to many other forms of the capacitor.

Capacitors are primarily made of ceramic glass or plastic depending upon purpose and size. We took our name from the fact that we were one of the earliest companies to use plastic rather than paper or mica as the dielectric in a high voltage capacitor. Make offer new corning glass avx corp cyfr10s200j glass dielectric capacitor.

Glass has a substantially higher melting point 14000c than the melting point of plastics 150oc that are presently used in capacitors. New corning glass avx corp cyfr10s200j glass dielectric capacitor. They are available in glass or glass composition and are covered by mil prf 11272 and mil prf 23269 or mil prf 11015 and mil prf 39014 respectively.

Typically a glass capacitor will have a relatively low capacitance value. The amount of charge stored per unit voltage is essentially a function of the size of the plates the plate materials properties the properties of the dielectric material placed between the plates and the separation distance ie. In a conventional capacitor the electric energy is stored statically by charge separation typically electrons in an electric field between two electrode plates.

Materials commonly used as dielectrics include glass ceramic plastic film paper mica air and oxide layers. Glass capacitors are used where the ultimate performance is required for rf circuits. 27pf 5 500v avx cy10c270j axial glass capacitor usa.

Develop a glass capacitor to meet the apeem temperature specifications of 140oc. Determine failure modes and predict life of a glass dc bus capacitor based on highly accelerated life testing. Insulating materials called dielectrics are commonly used in their construction as discussed below.

The ceramic capacitor gains its name from the fact that it uses ceramic materials for its dielectric. Cy series glass dielectric capacitors available in both. Now of course there are ceramic capacitors mica caps tantalum wet slug aluminum electrolytic paper andor plastic film capacitors and even still glass dielectric capacitors.

The nonconducting dielectric acts to increase the capacitors charge capacity.
