Working Principle

GRM155R61E225ME15D series are composed of multiple layers of high-purity ceramics that are fabricated to electrical characteristics by high temperature firing process. After firing, a very thin dielectric barrier layer of metal oxides is formed between two conductive electrodes. In this way, capacitors are formed.

In the working condition, when applying a voltage to the capacitor, electrical energy is stored in an electric field between the two electrodes. The electric field stores energy like a reservoir and releases it again when the voltage decrease. On the other hand, the electric current carries energy in the form of electric charge from the one electrode to the other.

The capacitance of a GRM155R61E225ME15D ceramic capacitor is determined by the value of the electric field which is determined by the resulting dielectric constant of the ceramic material and the surface area of the electrodes. The surface area of the electrodes increases when the diameter is increased and the capacitance increases accordingly. In addition, the capacitance of this series can be changed by altering the distance between the electrodes. This makes the series ideal for applications where precise capacitance values are needed.

Another important feature of GRM155R61E225ME15D is that its surface resistance is far lower than that of other types of capacitors. This makes it suitable for use in high frequency DC applications.

In conclusion, GRM155R61E225ME15D is a ceramic capacitor series that is used for general purpose capacitance, high capacitance, and high voltage applications. The series has a wide range of application fields such as audio, video, telecommunications, and military and aerospace applications. Its working principle, based on the formation of an electric field between two conductive electrodes, results in precise capacitance values that can be adjusted according to the needs of the application.
