Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as aluminum electrolytic capacitance or electrolytic capacitance) is a kind of capacitor consisting of aluminum foil and oxide film. The positive electrode of the capacitor is the aluminum foil with oxide film formed by electrolytic method, and the negative electrode is formed by metal film or carbon film. The working principle of three-in-one aluminum electrolytic capacitor is as follows: the electrolyte provides the ions to form a relatively stable oxide film on the aluminum sheet, thus forming an electric field between the sheets, so that the capacitor acts as an insulated medium. The dielectric strength of the capacitor depends on the thickness, roughness and chemical composition of the oxide film.

The EKMS251VSN102MA30S is a three-in-one aluminum electrolytic capacitor. The three major parts are the outer shell, the positive lead, and the negative lead. The outer shell is made of aluminum which is anodized which forms a protective layer. The positive lead is an electrolytic aluminum foil which is etched during the manufacturing process to create a single crystal grain boundary of aluminum oxide. The negative lead is another layer of electrolytic aluminum foil with additives that help reduce the oxide breakdown threshold.

The application fields for aluminum electrolytic capacitors are very wide. It is mainly used in electrolytic capacitor filter circuit, high-frequency DAC circuit, DC voltage summing circuit, AC power factor correction circuit, negative feedback loop filtering circuit, and audio signal amplification circuit. When used in dc voltage summing circuits, it can provide accurate transfer functions for dc gain and translinear signals. In addition, aluminum electrolytic capacitors are used to smooth the ripple current in power supplies, such as the voltage regulator 12 V, etc., can improve the power supply\'s output stability.

The working principle of EKMS251VSN102MA30S aluminum electrolytic capacitor is also based on the principle of its overall structure. It is a non-polar type aluminum electrolytic capacitor, which is marked with polarity at both ends, and its anode and cathode are indicated. The anodic lithium trivalent oxidation film forms the insulation film on the electrolytic aluminum foil of the aluminum electrolytic capacitor, which is a major factor in forming a capacitance. When the applied voltage exceeds the allowed breakdown voltage of the oxide film, electrons will appear in the capacitor and lead to an increase in the current and the failure of the capacitor. According to the size of the product, EKMS251VSN102MA30S aluminum electrolytic capacitor provides a peak operating ripple current of 7.6A, and its dielectric strength is 4V.

In summary, EKMS251VSN102MA30S aluminum electrolytic capacitor has a wide range of application fields, mainly in electrolytic capacitor filter circuit, and high-frequency DAC circuit, DC voltage summing circuit, AC power factor correction circuit, negative feedback loop filtering circuit, and audio signal amplification circuit and other circuits to improve the output stability of the power supply, and its working principle is based on the overall structure of its anode and cathode.
