The predominant application of all electrolytic capacitors is in power supplies.They are used in input and output smoothing capacitors, as decoupling capacitors to circulate the harmonic current in a short loop, as bypass capacitors to shunt AC noise to the ground by bypassing the power supply lines, as backup capacitors to mitigate the drop in line voltage during sudden power demand or as ...
A selected, but otherwise standard, polymer dielectric capacitor, when immersed in a compatible gas or liquid, can work usefully as a very low cost pressure sensor up to many hundreds of bar. Changing the distance between the plates Capacitors with a flexible plate can be used to measure strain or pressure.
Polymer capacitors are aluminum, tantalum or niobium electrolytic capacitors with conductive polymer as electrolyte; Supercapacitor is the family name for:
Plastic film capacitors potted in rectangular casings, or dipped in epoxy lacquer coating (red color) Film capacitors, plastic film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes.
A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...

In 1958, KEMET changed its market focus to the tantalum capacitor. In 1969, the company entered the market of ceramic capacitors. [1] In 1990, KEMET Electronics Corporation was acquired from Union Carbide and after two years, the company went public on the New York Stock Exchange under the symbol KEM. This ended all ties with Union Carbide. [1]
The matrix of a Structural composite supercapacitor is a polymer electrolyte that transfers load via shear mechanisms between the carbon fibers and has a reasonable ionic conductivity. [ 3 ] In a supercapacitor, the specific capacitance is proportional to the exact surface area of the electrodes . [ 4 ]
