the capacitor ceramics with high dielectric constant (barium titanate titanium monoxide) are extruded into circular tubes, discs or discs as the medium, and silver is plated on the ceramics as electrodes by the sintering method. it is divided into high-frequency porcelain and low-frequency porcelain. capacitors with a small positive capacitance temperature coefficient are used in highly stable oscillation circuits as loop capacitors and pad capacitors. low-frequency ceramic capacitors are limited to bypass or dc blocking in circuits with lower operating frequencies, or occasions where stability and loss are not high (including high frequency). such capacitors are not suitable for use in pulse circuits because they are easily broken down by pulse voltage.
