What are Types of Capacitors & Capabilities?

by Crazzy Paul Digital Markting Professional
A film capacitor is an electrical reservoir which stores electric energy and used in the type of items used in the production of many devices such as:
  • Amplifiers
  • Computers
  • Televisions
  • Radios etc.

All these components can be find in almost all the electronic circuits. These film capacitors include both aluminum and tantalum electrolytic. They are manufactured by an petrochemical formation of an oxide film onto a metal surface.

How Capacitors are Made & Capabilities?

The metal on which the film is formed works as the anode or positive terminal. The oxide film works as the dielectric, and a conducting liquid or gel acts as the cathode or negative terminal. Plastic film capacitors and tantalum electrolytic capacitors that have larger capacitance per volume ratios when compared with aluminum electrolytic.

In today's industry motor run capacitors are widely used in power applications including but not limited to DC Link, DC output filtering. The fan motor capacitors are also used for oscillators and resonant circuits. Some of the application areas where capacitors are used:
  • High pass filters
  • Low pass filters
  • Band pass filters

Films or Mylar capacitors can also be used for tuning circuits for audio crossovers in loud speakers, in hold A/D converters and in peak voltage detectors. When it comes to buying capacitors it is important to recognize what part family they belong in, and also try buying them from reputed pulse & power capacitor suppliers in Delhi/NCR India.

What are the Benefits of Capacitor?

An ideal industrial capacitor generally have a high resistance to dielectric and zero plates. However, there are capacitors that have some leakage current that pases through the dielectric between the two metal plates.

The leakage current that a capacitor release depends upon the leakage resistance of the dielectric medium being used in the object. In the same way an ideal metal capacitor does not lose any of the energy supplied by the source voltage as it is stored in the form of an electric field between the two plates. In real capacitors power is lost due to this leakage current and the resistance value of the metal plates.

So, capacitors have definitely changed & improved electronic devices and helped a lot in in the advancement of technology. However, when using electronic devices that have capacitors can store a huge amount of electric charge, so a person working in the field should always be careful.
