51capacitor dielectric and piezoelectric ceramics — ▪ ceramics Introduction advanced industrial materials that, by virtue of their poor electrical conductivity, are useful in the production of electrical storage or generating devices. Capacitors (capacitor) are devices that store… …
52Liquid dielectric — A liquid dielectric is a dielectric material in liquid state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. transformers, capacitors,… …
53RC time constant — In an RC circuit, the value of the time constant (in seconds) is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e. au = R × C . It is the time required to charge the capacitor, through the… …
54EIA Class 2 dielectric — The EIA Class 2 dielectric materials are ceramic dielectric materials used in ceramic capacitors. In comparison with the EIA Class 1 dielectrics they tend to have severe temperature drift, high dependence of capacitance on applied voltage, high… …
