Capacitors an electrical or electronic component that stores electric charges. Basically, a capacitor consists of 2 parallel plates made up of conducting materials, and a dielectric material (air, mica, paper, plastic, etc.) placed between them as shown in the figure. The specifications of capacitors are: 1. Capacitance Value
When selecting a capacitor, it is important to consider the dielectric material used. Various dielectric material groups feature different characteristics, advantages, and disadvantages. Though it is not mentioned in this table, air is sometimes used as a dielectric in high voltage applications. Dielectric characteristics.
This article briefly introduce niche types of electrostatic capacitors – Glass, MICA and Air and Vacuum Capacitors. Aluminum capacitors or tantalum plate capacitors with an oxide dielectric material are widely used for applications that require high capacitance.
Capacitors are distinguished by the materials used in their construction, and to some extent by their operating mechanism. “Ceramic” capacitors for example use ceramic materials as a dielectric; “aluminum electrolytic” capacitors are formed using aluminum electrodes and an electrolyte solution, etc.
Aluminum or tantalum plate capacitors with an oxide dielectric material are widely used for applications requiring high capacitance. These electrolytic capacitors have high instability, and poor tolerances, and their performance deteriorates when they are subjected to high leakage current or high temperatures.
Polyester, also known as Polyethylene Terephthalate or PET, is one of the most commonly used dielectric materials in film capacitors, alongside polypropylene. Relative to polypropylene, polyester generally has a higher dielectric constant, lower dielectric strength, higher temperature tolerance, and higher dielectric losses.
