Introduction of high frequency ceramic capacitors
It is suitable for high frequency circuit mica capacitors. In terms of structure, it can be divided into foil type and silver type. The silver electrode is directly deposited on the mica sheet by vacuum evaporation or infiltration, and the temperature coefficient is greatly reduced due to the elimination of the air gap, and the capacitance stability is also higher than that of the foil type. The frequency characteristics are good, the charge amount is high, the temperature coefficient is small, and a large capacity cannot be made. Widely used in high frequency electrical appliances and can be used as a standard capacitor.
