A brief overview about capacitors and their suppliers

A BRIEF OVERVIEW ABOUT CAPACITORS AND THEIR SUPPLIERS A passive electrical component that is precisely used for the purpose of “storing electricity� in the form of an electrical charge (either positive or negative) through an insulating material is known as capacitor. Some of the very commonly used capacitors are small capacitor beads used in different resonance circuits and large power factors correction electrical capacitors.

Irrespective of size and shape, all capacitors perform basic operations, which is to store electricity.

Construction of a capacitor It has two parallel conductive plates separated by excellent insulting materials (dielectric materials). DC current cannot flow through the capacitor due to its insulating layer as it blocks the voltage to be present across the plates in the form of an electrical charge. The conductive plates can be cylindrical, circular or rectangular in shape with the insulating layer (dielectric) being air, plastic, waxed paper or some form of a liquid gel.

How capacitors work?

Capacitors store two types of electrical charge, which is positive (+ve) charge in the form of protons or negative (-ve) charge in the form of electrons. When a voltage is placed across the electrical component, the positive charge

accumulates quickly on one insulating plate while a corresponding negative charge quickly accumulates on the other. For every positive charge accumulated at one plate, there is equal number of negative charge that will depart from the negative plate.

Due to the charge difference between the two insulating plates, the amount of charge on the capacitors always remains neural. The total amount of potential difference of charge present across the capacitor will depends upon how much charge was effectively deposited onto the plates by the work being carried out (done) by the source voltage and also by how much capacitance the electrical capacitor has.

Different between ideal and real capacitor Ideal electrical capacitor would have an extremely high dielectric resistance and 0(zero) plate resistance. Once the source voltage was removed, it should effectively results in the charge across the plates remaining constant indefinitely. But this is not true for real capacitors.

All the capacitors (real) have leakage current that efficiently passes through the dielectric between the two plates. The total amount of leakage current a particular has will totally depend upon the leakage resistance of the insulating material (dielectric) between the two plates.

Panasonic capacitors and their suppliers Panasonic and other reputed brands manufacturers different types of capacitors in order to meet the precise needs of their customers (electrical devices manufacturers). Panasonic capacitors are known for their low ESR, low leakage current, high ripple current, long lifetime, and small case size. So many manufacturers prefer Panasonic capacitors in construction of different electrical devices.

Quality, timely delivery, and ability to meet the bulk quantities within promised time frame are some of the factors many manufacturers consider while selecting wholesale Panasonic capacitors suppliers to purchase different types of Panasonic capacitors in bulk quantities.

Some of the leading electronics components distributors make mutually beneficial relationship with leading manufacturers in order to meet the bulk demands of capacitors. They also develop wide distribution network and appoint a team of qualified logistics professionals in order to ensure that the Panasonic capacitors are delivered within the promised time frame at their clients’ end.
