Aluminum electrolytic capacitors are widely used in electronic circuits and play a key role in electric power, communication technology, computers, automation technology, labor division, domestic electric appliances and other modern industries. Among them, LNUN7472MSEHBN is a kind of high-tech axial aluminum electrolytic capacitor. This kind of capacitor has excellent characteristics and technological properties, and has been widely used in modern life.

Application field

Aluminum electrolytic capacitors are the most commonly used capacitors in electronic circuits. The voltage value of aluminum electrolytic capacitors is relatively large, reaching hundreds of thousands of volts, and the capacitance value is relatively large, often dozens of microfarads to hundreds of microfarads or more. Commonly used varieties are three-pin, five-pin, and screw-type. LNUN7472MSEHBN aluminum electrolytic capacitors are mainly used in the electromechanical and electrical equipment for signal filtering, buffering, elimination effect of peak and surge, pulse frequency, harmonics, surge and voltage regulator etc. applications.

Working principle

The construction of the aluminum electrolytic capacitor is basically composed of two parts: the anode and the cathode. The anode aluminum foil is formed by anodizing, and a large number of extremely thin oxide layers are formed on the surface of the aluminum foil. The positive electrode is connected to the aluminum oxide film and the negative electrode is connected to the aluminum foil. Therefore, a very thin electrolyte is formed, and the electrolyte is a single bond that connects the anode and cathode. In terms of electrical performance, aluminum electrolytic capacitors have the characteristics of large capacitance, low loss, and good electrical properties. When a voltage is applied, the uniform electric field formed in the oxide film will attract more electrolyte to move to the anode side. This process increases the capacitance. The increase in capacitance will be proportional to the electric field between the two electrodes, and the larger the electric field, the larger the capacitance.

LNUN7472MSEHBN aluminum electrolytic capacitors have the advantages of long service life, good reliability and stable performance. Different types of aluminium electrolytic capacitors have different characteristics. Therefore, users should choose the appropriate products according to their actual needs.
