The schematic diagram of a ceramic capacitor can be broken down into four main parts: the positive terminal, the negative terminal, the dielectric material, and the metal plates. The positive and negative terminals represent the source and destination of an electrical current, respectively.
The value of a ceramic capacitance will not be directly mentioned on the capacitor. There will always be a three digit number followed by a variable; let’s learn how to identify the value using these numbers. Consider the following capacitor. As you can notice, these three digits are split into two digits and the third one is the multiplier.
The ceramic capacitor code remains the same for its various types. The capacitors of this type consist of three digits followed by one alphabet. The initial digits that are first two, represents the value of the capacitance. The third number present on it represents the multiplier for the initial values.
A ceramic capacitor is used to store electric charge and supply current to a circuit. It’s composed of two metal plates separated by a dielectric material, typically ceramic or plastic. The metal plates act as a plate of electrodes that hold and transfer electrical energy between them.
Other types of capacitors available include: ceramic, polystyrene, polyester, polypropylene and mylar. None of these types are polarity sensitive, and can be connected in either orientation. Some types have the value marked on the case, others (including ceramic) use a 3 digit code.
The Ceramic Capacitor is made by making a finely grounded powder of a dielectric material which is either paraelectric material like the Titanium dioxide or ferroelectic material like the barium titanate.
