Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or uf equal to 10 6 farads.

Third column indicates the tolerance value sub columns for above and below 10pf of the capacitor.īasically a capacitor is formed from two conducting plates separated by a thin insulating layer. Home capacitors capacitor colour codes capacitor colour codes generally the actual values of capacitance voltage or tolerance are marked onto the body of the capacitors in the form of alphanumeric characters. Usually the first two digits of the code represent part of the value. C0g is a class 1 dielectric so its not included more on this later. X5r and x7r are in class 2 and y5v is in class 3. The three character code with the letter number letter format is used for capacitors with class 2 and class 3 dielectrics. Understanding the basics of them helps you to choose the capacitor for your application. There are a number of subtle differences in the capacitor codes and markings used for different types of leaded capacitors. The types of capacitors available range from very small delicate trimming capacitors using in oscillator or radio circuits up to large power metal can type capacitors used in high voltage power correction and smoothing circuits. There are different types of capacitors that are manufactured in many forms styles and materials. The various parameters of the capacitors such as their voltage and tolerance along with their values is represented by different types of markings and codes. The capacitor color code for ceramic capacitors is shown in the above figure in which first column represents different types of colors the second column represents the value indicated by a specific color. Many leaded capacitors are quite large although some are smaller. Another type the electrochemical capacitor makes use of two other storage principles to store electric energy. Work out the capacitance units from context. The capacitance value of an electrochemical capacitor is determined by two high. In contrast to ceramic film and electrolytic capacitors supercapacitors also known as electrical double layer capacitors edlc or ultracapacitors do not have a conventional dielectric.Ĭapacitor types and codes.
