Types Of Capacitor - Comparison
... Features and applications as well as disadvantages of capacitors Capacitor type Dielectric Features/applications Disadvantages Ceramic capacitors ... Available in voltages up to 15,000 V Low permittivity ceramic, capacitors with low volumetric efficiency, larger dimensions than Class 2 capacitors Ceramic Class 2 capacitors ferroelectric ... Slightly microphonic Film capacitors Metallized film capacitors PP, PET, PEN, PPS, (PTFE) Metallized film capacitors are significantly smaller in size than film/foil versions and have self ...
Types Of Capacitor - Electrical Characteristics - Frequency Dependence
... Most discrete capacitor types have more or less capacitance changes with increasing frequencies ... strength of class 2 ceramic and plastic film diminishes with rising frequency ... This phenomenon for ceramic class 2 and plastic film dielectrics is related to dielectric relaxation in which the time constant of the electrical dipoles is the reason for the frequency dependence of permittivity ...
Types Of Capacitor - Types and Styles - Film Capacitors
... Film capacitors or plastic film capacitors are non-polarized capacitors with an insulating plastic film as the dielectric ... The dielectric films are drawn to a thin layer, provided with metallic electrodes and wound into a cylindrical winding ... The electrodes of film capacitors may be metallized aluminum or zinc, applied on one or both sides of the plastic film, resulting in metallized film capacitors or a separate metallic foil overlying the film ...
Types Of Capacitor - Electrical Characteristics - Limiting Current Loads - AC Current
... An AC load only can be applied to a non-polarized capacitor ... Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors ... The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range ...
Types Of Capacitor - Electrical Characteristics - Long Time Behavior, Aging - Aging
... In ferroelectric Class 2 ceramic capacitors, capacitance decreases over time ... The rate of aging of Class 2 ceramic capacitors depends mainly on its materials ... The typical aging of X7R ceramic capacitors is about 2.5 nbs% per decade ...

Famous quotes containing the word film:

    A good film script should be able to do completely without dialogue.
