Introduction

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are the most widely used and largest capacity capacitors. These capacitors use aluminum as the anode material, a layer of paper is placed outside the aluminum foil, and the electrolyte is filled between the two to form a double layer of electrolyte capacitance. The model of 450HFG1000MBN35X95 aluminum electrolytic capacitors is one of those capacitors. This paper will briefly introduce the application field and the working principle of the 450HFG1000MBN35X95 aluminum electrolytic capacitor.

Application field

The 450HFG1000MBN35X95 aluminum electrolytic capacitors have a number of applications, including power conversion, power conditioning, power storage, energy harvesting, low frequency audio, pulse circuits, peak current suppression, RF circuits, driving circuit and communication. It can use in electric power equipment, electronic instrument and communication products.

Working principle

The 450HFG1000MBN35X95 aluminum electrolytic capacitors use anode material of aluminum, which is divided into two identical parallel aluminums. When current flows through, it forms two double layers of electrolyte capacitance, which is formed by anode aluminum-electrolyte-cathode aluminum Foil, and a gas insulation film separates the two double layers. With the increase of voltage, the electrolyte breaks down to form electrons and gas. At this time, the capacitor’s voltage capacity increases and super sharp electric pulses can be generated. At the same time, reverse current is intercepted in the breakdown stages, and the over-transmission of high-voltage signals is prevented, and thus power frequency transformer is protected. When the capacitor charges, the positive ions of electrolyte move to the anode and the negative ions move to the cathode. The positive ions form a double layer which is called the Helmholtz layer and other negative ions form a diffuse double layer. There is an electric field between two double layers and certain energy is generated. The same phenomenon occurs when the capacitor is discharging, but the direction of current flow is reversed. When the capacitor is not working, the electric double layers will combine to form a certain amount of capacitance. Due to a layer of paper covering the anode and the electrolyte layer, this capacitor has a higher voltage capacity than ordinary electrolytic capacitors.

Conclusion

In conclusion, the 450HFG1000MBN35X95 aluminum electrolytic capacitor has a wide range of applications in power conversion, power conditioning, power storage, energy harvesting, low frequency audio, pulse circuits, peak current suppression, RF circuits, driving circuit and communication. Its working principle is that when current flows through, it will form two double layers of electrolyte capacitance, with an electric field existing between two double layers, and certain energy is generated.
