Ferrodielectric Capacitors

Ferrodielectric capacitors are shaped as tubes, monoliths, multilayers, or disks. They normally use ceramic dielectrics because of their high dielectric constants (1000 s, 30,000). However, the capacitance of a ferrodielectric ceramic capacitor is strongly dependent on the operating temperature, frequency, and voltage, where the effect of instability on the relative capacitance with respect to dielectric strength is demonstrated using two different e, values. These types are called non-linear capacitors and will be discussed briefly below.

Typical Class II materials are ferrodielectric ceramics and polymer electrolytes with high dielectric constants. They are used to develop high capacitance capacitors. For example, metalized polymer foils can achieve a few thousand picofarads to a few microfarads an electrolytic capacitor can offer a capacitance in the range of a few to several thousand microfarads some... 

Depending on the dielectric materials and applications, various types of capacitors have been designed, fabricated, and commercialized. These capacitors are categorized as fixed, variable, power, high voltage, interference suppression, ferrodielectric, polar polymer dielectric, linear, and nonlinear capacitors [7]. The following sections will briefly discuss each type.
