Axial Capacitors And Radial Type Capacitors - Their Features And Usage

by Crazzy Paul Digital Markting Professional
Capacitor is a device generally used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator. The capacitor was originally known as condenser. Two types of capacitors namely axial capacitors and radial type capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. The conductive plates on the either side can be circular, rectangular or cylindrical in shape

Measurement unit of capacitor:

Capacitance is the electrical property of a capacitor like that of AC/DC Link Capacitor and is the measure of a capacitors ability to store an electric charge on its two plates. If a voltage (V) is connected across the two plates of capacitors, a positive electrical charge (Q) in coulombs will be present on one plate and a negative electric charge on the other. Then the capacitance of the capacitor can be represented by an equation as C=QV

Types of capacitors:

There are generally two types of capacitors namely radial type capacitors and axial capacitors. Radial capacitors have two leads which stick out from the bottom of the capacitor while the axial capacitors have one lead that sticks out from either end.

High power convertor capacitor:

IGBT Snubber capacitor are designed for high power convertors and use a low loss dielectric of polypropylene film. These capacitors are unique since they have extended aluminium foil electrodes with polypropylene film dielectric and are impregnated.

Capacitors can be distinguished in two forms as per AC/DC Link Capacitor among which DC link capacitor is more prevalent. The DC link capacitors are a capacitor which is connected in the DC link between a rectifier and an inverter in convertor circuits. These capacitors are connected in parallel between the positive and negative conductor.

Polarized and non-polarized capacitors:

Some families of capacitors may contain capacitors that are polarized and non-polarized in nature. Polarized capacitors are specifically built for use with DC fluctuating voltages. A polarized capacitor has a positive lead that must be placed at a higher potential in a circuit and has a negative lead that must be placed at a lower potential. Placing a polarized capacitor in a wrong direction may even destroy it. A non-polarized capacitor can handle both DC and AC voltages.

Film capacitors for automobiles:

Horn capacitors have already become automobile industry benchmark and are widely used as O.E components by several reputed Horn Capacitor Manufacturers. The horn capacitors are specifically meant to serve withstand high voltage peaks, eliminating expensive soldering works, vibration proof and operating in high temperature.
