What are ceramic capacitors?

Some articles on ceramic capacitor, capacitor, ceramic, capacitors, ceramics, ceramic capacitors:

Ceramic Capacitor
... A ceramic capacitor is a fixed value capacitor with the ceramic material acting as the dielectric ... It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes ... The composition of the ceramic material defines the electrical behavior and therefore the application of the capacitors, which are divided into two stability classes Class 1 ...
Ceramic Capacitor - History
... Since the beginning of the study of electricity, ceramics like porcelain have been used as insulators ... It was obvious to use these ceramic materials, including mica, steatite and titanium dioxide (rutile), as dielectric for the first ceramic capacitors ... The capacitors with paraelectric titanium dioxide as a dielectric had a linear temperature dependence of the capacitance for temperature compensation of resonant circuits and were produced ...
Ceramic Capacitor - Construction and Styles
... Basic structure of ceramic capacitors Construction of a multilayer ceramic chip capacitor (MLCC) Construction of a ceramic disc capacitor Ceramic capacitors are composed of a ... From these powder mixtures, the ceramic of the capacitor is sintered at high temperatures ... The ceramic forms the dielectric of the capacitor and serves as a carrier of the metallic electrodes ...
Electrical Characteristics - Ceramic Capacitors Behavior From Soldering
... Ceramic capacitors may have changes of their electrical parameters due to soldering stress ... especially for SMD styles, can cause in ceramic capacitors changes of the contact resistance between terminals and electrodes ... For ferroelectric class 2 ceramic capacitors the soldering temperature is above the Curie point ...
Ceramic Capacitor - Electrical Characteristics - Insulation Resistance and Self-discharge Constant
... The resistance of the dielectric of a capacitor is never truly infinite, leading to some level of DC “leakage current”, which is the reason for self-discharging of a charged capacitor over ... For ceramic capacitors this resistance placed in parallel with the capacitor in the series-equivalent circuit of capacitors is called “insulation resistance Rins” ... over the insulation resistance with decreasing capacitor voltage follows the formula With the stored DC voltage and the self-discharge constant That means, after the ...

Famous quotes containing the word ceramic:

    He had first discovered a propensity for savagery in the acrid lavatories of a minor English public school where he used to press the heads of the new boys into the ceramic bowl and pull the flush upon them to drown their gurgling protests.
    Angela Carter (1940–1992)
