450CXW47MEFC12.5X40 application field and working principle

Aluminum electrolytic capacitors are generally used in the power electric equipment, computer accessories, automobiles and other electronic equipment. They are used in different applications, such as various time constants, smoothing noise cancellation, and pulse forming.

The 450CXW47MEFC12.5X40 is a type of aluminum electrolytic capacitor with low cost, medium lifetime and good insulation performance. This type of aluminum electrolytic capacitor has a high performance in hum filtering and decoupling, and it is widely used in a variety of electronic circuits.

The 450CXW47MEFC12.5X40 is a polarized aluminum electrolytic capacitor with non-solid electrolyte, which is specially designed for power supply applications such as switching power supplies. It has low dissipation factor and high insulation resistance, so that it can provide excellent EMI hum suppression, and it has good stable performance and excellent low temperature performance.

The working principle of aluminum electrolytic capacitor is based on the dielectric polarization of electrolyte. The electrolyte is a liquid compound of resin and organic solvent, which has good conductive properties, and the electrolyte is contained in the cell with a positive electrode and a negative electrode. When the voltage is applied to the positive and negative electrodes of the cell, the electrolyte gasifies and forms and electric double layer capacitor, that is, the electric double layer capacitor is formed by the accumulation of a large amount of charged ions on the surface of the positive and negative electrodes.

The layer formed by the accumulated ions acts as an insulation layer between the two electrodes, so that the two electrodes have different electric charge values. The electric charge difference can form an electric field of reverse polarity, which stores electrical energy.

The capacitance of the aluminum electrolytic capacitor is usually expressed in Farad. The higher the capacitance, the more energy the capacitor can store. The capacitance value of this type of aluminum electrolytic capacitor is usually between 0.15F-2000F.

The voltage capacity of aluminum electrolytic capacitor is also important, and the voltage capacity of 450CXW47MEFC12.5X40 varies according to different models. Generally, the voltage capacity is 350V-1100V, while there are also special models with higher voltages.
