Types of Capacitors fixed and variable is the main


Types of capacitors in electronic circuits is divided into two kinds , namely capacitors polar and non- polar capacitor . In the mean polar capacitor is a type of capacitor that is bi-polar and has a positive polarity / negative .

This capacitor is made of electrolyte material which has a large capacitance value compared with capacitors using a dielectric material .

While in the mean non-polar capacitor is a type of capacitor does not have a positive and negative polarity at both poles. These capacitors can also be used in turn . These capacitors usually have a small capacitance value because it is made of ceramic material and mica .

Although both types of capacitors are widely used to store electrical charges , but there are still many differences of the two types , among which is the material used and also function in everyday usefulness .


Type capacitors we can also differentiate into several parts , which is a type of ceramic capacitors , electrolytic capacitors ( elco ) , tantalum capacitors , multilayer capacitors , polyester film capacitors , elekctric double , super capacitors , trimer and tuning capacitor .

The nature of the capacitor is storing electric charge and can not flow through the DC ( Direct Current ) but passable AC ( Alternating Current ) and can also serve as an impedance ( resistance whose value depends on the frequency ) .
Based on the capacitance value , the capacitor is divided into two parts , namely fixed capacitors and variable capacitors .

For those types of multilayer capacitors is a capacitor made ​​of the material . This capacitor is similar to ceramic capacitors , the difference is only in the number of layers that make up the dielectric .

Dielectric material arranged with many layers with a thickness of 10 to 20 μm and a plate electrode is made ​​of pure metal . In addition , the shape of this type of capacitor is also small and has good temperature characteristics in comparison with other capacitors .

Capacitors functions in electronic circuits is a connector on each piece in the series , separating the alternating current from direct current , as the filter on the power supply circuit , a frequency generator at the transmitter electronic circuit and also saves power at the circuit fluorescent lamp

Electrolytic Capacitor

Electrolytic capacitors or also called Elcho included in the fixed value capacitors . This type of capacitor has an insulating material made ​​of electrolyte and tubular . Electrolyte capacitors which have polarity direction of the Positive and Negative use of aluminum for packaging as well as Negative terminal .

Capacitor Paper

Capacitor paper , is a capacitor including the capacitor type calculation remains (Non Variable) , and has a paper insulation material , and generally ranges between paper capacitor values ​​up to 300μF 4μF

Tantanum Capacitor

Tantanum capacitors , are capacitors that use metal materials tantanum as Anode terminal itself ( + ) . Tantanum capacitor has a positive and negative polarity direction ( + and - ), such as electrolytic capacitors . The insulation material was made of electrolyte material
