Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most popular and widely used capacitor types due to their high capacitance values and relatively small size and weight. They are constructed with a solid aluminum oxide layer between the two conductive plates of the capacitor body, with the oxide acting as the dielectric medium. This oxide layer is formed when an electrically charged anode is soaked in an electrolyte, forming a thin layer of aluminum oxide on its surface. The oxide layer is then sealed with a hydrophobic material, such as a polyester film, and the capacitor body is covered with a heat-sealing outer casing.

The 400CXW270MEFC18X50 capacitor is an aluminum electrolytic capacitor. It is designed for use in both AC and DC applications and features a versatile, space-saving package. It has a rated voltage of 400V, a capacitance of 270MEFC18X50 and is capable of operating over a temperature range of -40 to +105°C. The capacitor is suitable for use in a variety of applications, such as power factor correction, motor drive, and power supply.

The working principle of the 400CXW270MEFC18X50 capacitor is simple. When the metal capacitor body is applied with a voltage, the oxide layer on its surface becomes an insulating material. This ions in the electrolyte, which are attracted to the charged surface of the oxide layer and accumulate on it, Electric current is then passes through the electrolyte, bridges the oxide layer, the and charges the capacitor’s plates. As the plates are charged, the oxide layer changes its capacitance. When the voltage is removed, the oxide layer reverts to its original capacitance, discharging the capacitor’s plates. This cycle is repeated with each applied voltage.

In conclusion, the 400CXW270MEFC18X50 aluminum electrolytic capacitor is a versatile and space-saving component suitable for a variety of applications. Its efficient working principle makes it a popular choice for many different industries and applications.
