If the positive to the positive terminal and the negative to the negative terminal as an incorrect polarization will break the insulating oxide layer and there will be permanent damage. google_ad_slot = "5724286408"; The dielectric materials which are used between these metallic plates are paper, ceramic, or rubber depending on the application of the capacitor. When reading schematics, repairing radios and buying capacitors, you often must convert between uF, nF and pF. They are also used for blocking the DC signals so that AC signals are passed through. Index. The last colour indicates the voltage rating. Here in this article, we help you decode and understand the uses of one of the most common types of capacitors . Polar capacitors are further classified into two types: 1.1.1. Paper capacitor is also known as a fixed capacitor in which paper is used as the dielectric material. In the code above A and B indicates 1 st and 2 nd digits and D is multiplier and T is tolerance. Then the 4 = 1st digit, the 7 = 2nd digit, the 3 is the multiplier in pico-Farads, pF and the letter J is the tolerance and this translates to: 47pF * 1,000 (3 zero's) = 47,000 pF , 47nF or 0.047 uF The J indicates a tolerance of +/- 5% The capacitor is a passive device that is available in a wide variety. The general voltage range of these capacitors is from 50 V to 2 kV. The differences between the markings and codes of the various types of lead capacitors are very minimal or marginal; but nevertheless these differences are many in number.

Method of Finding the value/Meaning of codes of capacitor. Examples of capacitor uses: Electrostatic capacitors (film or ceramic) are using IR parameter while for electrolytic capacitors with their relatively low IR rather the DCL leakage current is specified. Capacitor values are usually tiny -- often in the millionths or billionths of a Farad. The amount of electric charge stored by the paper capacitor is fixed. Exceptionally high C/V ratio. Electrolytic capacitors are used when there is a requirement for large capacitance. dielectric used that capacitors are grouped and designated according to the type of dielectric. If the reading goes from zero to infinity then the capacitor is considered to be in good condition. To make it a bit more difficult, not all the capacitors share the same labeling system, so we have to make a difference between the main 3 capacitor types: electrolytic, ceramic and polyester.We'll start with electrolytics as they are the most straightforward ones to read.Polyester and ceramic share the same labeling system, but with some small differences.
