Introduction to Aluminum Electrolytic Capacitors

Electrolytic capacitors are passive electrical components that all electronic and electrical engineers should be familiar with. In order to satisfy the ever-increasing demand for storing and releasing electrical energy rapidly and accurately, power supplies and analog circuits must all rely on electrolytic capacitors. As a type of electrolytic capacitor, aluminum electrolytic capacitors are widely used in both consumer electronics and industrial applications.

400SXW100MEFC18X45: A Type of Aluminum Electrolytic Capacitor

The 400SXW100MEFC18X45 is a kind of long-life, high-temperature aluminum electrolytic capacitor manufactured by Beijing Aerospace Changxin Technology Co., Ltd. It is characterized by its high ripple current and high temperature performance. The characteristics of this type of aluminum electrolytic capacitor typically remain stable up to 105 degrees Celsius. The housing of this aluminum electrolytic capacitor is composed of zinc alloy and boxless sealed aluminum, which sufficiently ensures the safety and reliability of the capacitor.

400SXW100MEFC18X45 Application Field

This type of aluminum electrolytic capacitor is mainly used for the purpose of smoothing and filtering, decoupling energy storage, and voltage pulse generation in circThe main application fields of the 400SXW100MEFC18X45 aluminum electrolytic capacitor include office machines, such as computers and their related peripherals, consumer electronics, such as television sets and stereos, industrial automation equipment, automotive electronics, industrial lighting, and renewable energy storage solutions.

400SXW100MEFC18X45 Working Principle

As with any other type of electrolytic capacitor, the 400SXW100MEFC18X45 aluminum electrolytic capacitor works on the principle of charging and discharging electrical charges from one side of the capacitor (the anode) to the other side (the cathode) through two polarizing layers.The two polarizing layers of the 400SXW100MEFC18X45 aluminum electrolytic capacitor are constructed from a sputtered aluminum film and a vitreous coating (electrolyte). The sputtered aluminum film is an oxidized film that is made up of extremely tiny, uniform, and mechanically stable particles. This film provides the electrical path for electrons to flow between the anode and the cathode. The vitreous coating is an aqueous solution of an ionic compound that serves as the electrolyte.

Advantages of 400SXW100MEFC18X45

The 400SXW100MEFC18X45 aluminum electrolytic capacitor offers several advantages over other types of capacitors. Firstly, it is able to tolerate very high ripple currents. As a result, it can be used in power supplies and other circuits that require frequent charging and discharging of currents. Secondly, because it is composed of an aluminum film, the 400SXW100MEFC18X45 aluminum electrolytic capacitor does not suffer from thermal drift, which is a phenomenon that affects the operation of certain other types of capacitors. Thirdly, due to the low impedance of the sputtered aluminum film, the 400SXW100MEFC18X45 aluminum electrolytic capacitor can be used to protect against sudden, large voltage spikes and other power electronic problems. Lastly, the 400SXW100MEFC18X45 aluminum electrolytic capacitor is cheap and easy to find, which makes it a popular choice for many applications.

Conclusion

In conclusion, the 400SXW100MEFC18X45 aluminum electrolytic capacitor is a long-lasting, high-temperature capacitor suitable for a wide range of consumer and industrial applications. It offers many advantages over other types of capacitors, such as a high ripple current tolerance, low thermal drift, low impedance, and affordability.
