Working Principle Of The EMVY101GRA101MKE0S Aluminum Electrolytic Capacitor

The EMVY101GRA101MKE0S Aluminum Electrolytic Capacitor works by storing electrical charge in the form of metal ions inside an electrolyte. The metal ions, usually made up of aluminum, are held in a matrix of small particles, typically 1-2nm wide. This matrix is held in an oxide layer that acts as a dielectric, helping to maintain the electrical charge.

When an electric field is applied, the ions in the matrix move and rearrange themselves, which results in a change of charge. This then causes a current to flow through the capacitor, allowing it to store and release electrical energy. The capacitance of the capacitor is determined by its physical parameters, such as the thickness of the layer, the shape of the particles in the matrix and the dielectric constant of the electrolyte.
