To construct a ceramic capacitor, either 1) a homogeneous block (single-layer capacitor), or 2) many layers (multilayer capacitor), give rise to a monolithic ceramic body. In an AC circuit, it is a frequency-dependent resistor.Ĭeramic capacitors also have no polarity and a fixed capacitance, but they use ceramic materials for the dielectric material.In a DC circuit, it is a charge storage device.That means the capacitor can assume a different role depending on the circuit: This energy release takes place at a defined rate over a certain period depending on its design characteristics.Ī capacitor is thus an energy reservoir, which blocks the direct flow of current with DC voltage and allows the flow of current with AC or pulsating voltage depending on its capacitance and the given frequency. It is calculated from the field constant, the relative permittivity of the dielectric used, the effective area (the overlapping area of the electrodes), and the thickness of the dielectric or the separation produced between the electrodes.Īs an electronic component, a capacitor is able to store electrical energy and then release it again. The capacitance of a capacitor describes its capacity to store electric charges. These are the three key parameters used to distinguish the power and manipulate the performance of a capacitor. You can see the relationship between the electrodes (1), the dielectric material (2), and the distance between electrodes (3) in the image provided. They are always separated by an insulating material: the dielectric. The structure of a capacitor always consists of two conducting surfaces: the electrodes (sometimes referred to as sheets). A capacitor describes every arrangement for storing stationary electric charges. So this is how a capacitor value/code calculator calculates the ceramic capacitor value from the capacitor code, or vice versa.The journey into the world of capacitors begins with the structure of the atom. The capacitance value will be calculated as follows: Similarly if the capacitor code is 152, the 3 rd digit is 2 so multiplier factor is 100. To understand how multiplier works, let’s take an example of a capacitor with code ‘104’.Īs first two digits are 10 and the 3 rd digit is 4, so multiplier factor is 10000, the total capacitance value in pF is as follows: If 3 rd digit is 6, it means multiplier factor of 1000000. If 3 rd digit is 5, it means multiplier factor of 100000. If 3 rd digit is 4, it means multiplier factor of 10000. If 3 rd digit is 3, it means multiplier factor of 1000. If 3 rd digit is 2, it means multiplier factor of 100. If 3 rd digit is 1, it means multiplier factor of 10. If 3 rd digit is 0, it means multiplier factor of 1. For example if a ceramic capacitor has a code ‘5’ and other has ‘47’, their respective capacitance values are 5 pF and 47 pF.įor 3 digit’s capacitor code, the first two digits are the capacitance value in pF and the third digit is a multiplier factor of first two digits to calculate the final capacitance value of the capacitor. If the capacitor code consist only 1 or 2 digits, it is simply their capacitance value in PicoFarads (pF). For electrolytic capacitors, simply capacitance values are written on them.Ĭeramic capacitors encoding consists 1-3 digits. By using this capacitor value calculator, we can calculate the value of that capacitor, or vice versa. How Capacitor Value/Code Calculator Works?Īs ceramic capacitors have less surface area because of their tiny size, their value is not written in the capacitor, instead an encoded code is written on them. This Capacitor Code Calculator calculates the ceramic capacitor code upon providing the capacitance value of the capacitor in the input field below.
