It consists of aluminum sheets and paper sheets.
Paper dielectric capacitor uses. It is a commonly used type. Plastic capacitors inc manufactures a wide variety of standard catalog plastic film andor paper dielectric capacitors high voltage transformers ac to high voltage dc power packs pulse forming networks and specialty lcr networks. This is the type of device connected to the station tuning control of a radio.
Usually with 100 khz or so being the upper limit. This type of capacitors are used in radio and electronic circuits where very low losses or variable capacitance are required. One of the advantages of the capacitor is that there is very little change of capacitance with time and voltage applied.
The film capacitor is prepared extremely thin using the sophisticated film drawing process. Here the dielectric in between the plates is paper. It is available in nano farad ranges.
As the name implies this capacitor uses a polypropylene film for the dielectric. The film capacitors are also capacitors and they use a thin plastic as the dielectric. The paper sheet is covered or soaked with oil or wax to protect it from outside harmful environment.
This type of capacitor is also used for low frequencies. It is good for filter applications in audio circuits. The capacitance range of the paper capacitor is from 0001 to 2000micro farad and the voltage is very high which is up to 2000v.
Commonly it is rated for high voltages. Paper capacitor is a capacitor that uses paper as the dielectric to store electric charge. The images shown in above.
Use aluminium sheets and paper sheets for constructing it.
