The Brief Introduction of Ceramic Capacitor

Ceramic capacitor uses ceramic as a dielectric, spraying silver layer on both surfaces of the ceramic substrate, then by low-temperature firing silver film as the plates.

Its appearance mostly is sheet-shaped, also have a tubular or circular shape.

Wide variety of ceramic capacitors, dimensions vary considerably. By using the voltage can be divided into high, medium and low-voltage ceramic capacitors. In terms of temperature coefficient, the dielectric constant can be divided into a negative temperature coefficient, positive temperature coefficient, zero temperature coefficient, high dielectric constant, low dielectric constant. In addition, I, II, III type classification.

General ceramic capacitor compared with those of other capacitor has the advantage of higher temperature, high specific capacity, good moisture resistance, small dielectric loss, temperature coefficient of capacitance can be selected in a wide range. Widely used in electronic circuits, the amount is very considerable.
