Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used because of their relatively small size and large capacitance values. They are composed of two aluminum foils which are separated by a thin layer of dielectric material. A current is then passed through this dielectric material, allowing electrons to travel from one aluminum foil to the other, thus building up an electrical charge. As charge accumulates, the capacitance increases. The most common type of aluminum electrolytic capacitor is the “CKE100M”. This particular capacitor is capable of producing an extremely high capacitance and can be used in a variety of applications.

476CKE100M application field and working principle

The 476CKE100M aluminum electrolytic capacitor is mainly used in high voltage rectifiers, power supplies, and switching power supplies. Capacitors of this type are used to store electrical energy and reduce the effects of electromagnetic interference. It is a low-profile aluminum electrolytic capacitor with a voltage rating of 100V and a capacitance range of 0.1 – 100µF. The 476CKE100M has an extended product life due to its unique, double-foil design with enhanced dielectric strength.

The working principle of the 476CKE100M aluminum electrolytic capacitor is based on the electric properties of electrolysis. When a direct current is applied, an electric field builds up between two electrodes in the capacitor. This electric field attracts ions from a fluid electrolyte that is contained inside the capacitor. The ions then build up onto the anode and the cathode to create a depletion layer. This depletion layer acts as a dielectric material between the two electrodes, creating a capacitance.

When a voltage is applied across the capacitor, the current begins to flow through the electrolyte from the anode to the cathode. This current causes ions to be released from the electrodes, forming an electric charge on the capacitor’s plates. This electric charge accumulates, increasing the capacitance of the 476CKE100M aluminum electrolytic capacitor. The higher the voltage, the higher the capacitance.

The 476CKE100M aluminum electrolytic capacitor is a highly efficient and reliable choice for a variety of applications, from power drivers and drivers for computer peripherals to inverter circuits and power supplies. Its wide capacitance range, extended life, and low profile make it suitable for a variety of applications.
