Ceramics Constant K

The dielectric constant k and loss factor tan d can be measured using a standard impedance bridge or an impedance analyzer both of which provide a direct reading.

Ceramics constant k.

The more resin the lower the k. We have collected a number of charts detailing applications and properties for some of the most commonly used ceramic materials. While the data in these charts is in most cases typical of what you will find from ceramic component suppliers it is only intended to be a general point of reference and should not be used for material selection or specification. 6 cheap shielded cables are often made with this stuff but these are only suitable for audio frequencies or low rate data communications.

Measurements are generally carried out at 1 khz. The loss factor represents the ratio of resistance to reactance of a parallel equivalent circuit of the ceramic element figure 3. At present the thermal conductivity of the prepared beo ceramics can reach 280 w m k which is 10 times higher than that of aluminum oxide al2o3 ceramics. The relative dielectric constant k is the ratio of the amount of charge that an element constructed from the ceramic material can store relative to the absolute dielectric constant 0 the charge that can be stored by the same electrodes when separated by a vacuum at equal voltage 0 8 85 x 10 12 farad meter.

The range of ks for common ceramic dielectrics is shown in table 15. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. 5 varies somewhat by exact resin content.
