Aluminum Electrolytic Capacitors

400CXW100MEFC18X25 application field and working principle

Aluminum electrolytic capacitors are passive components used to temporarily store electric charge with the help of an electrolyte, most frequently this consists of an organic solvent or an aqueous solution. With the components of an electrolytic capacitor being a positively charged anode, negatively charged cathode, and a liquid electrolyte between them, the resulting capacitor from the combination of all of these components is basically a kind of electrochemical cell. This type of capacitor is characterized by its high capacitance density, which is an impressive feature compared to other types of capacitors. This makes them perfect for storing a large amount of charge despite their comparatively small size.

When it comes to 400CXW100MEFC18X25 capacitors, these are also known as "Electrical Double Layer Capacitors," which operate with an extraordinary high capacitance values for their size. The 400CXW100MEFC18X25 is a versatile and powerful variant of these types of capacitors with an extensive temperature range, high voltage ratings, very low ESR values, and very high ripple current and energy-storage capabilities. With these features, 400CXW100MEFC18X25 capacitors are perfect and highly recommended for power back-up applications.

Working Principal of 400CXW100MEFC18X25 Capacitors

Aluminum electrolytic capacitors are made from two-or three-layer structures; the dielectric layer is made from a mixture of organic compounds and the electrolyte. Additionally, the structure consists of a cathode terminal, which is usually made from aluminum foil and a separate anode terminal made from a metal or carbon foil. The whole structure is embedded in an aluminum can with the anode and cathode terminals placed in it. Once the system is connected to a power source, the current initiates a chemical reaction in the electrolyte, which results in the separation of electrons and ions.

The 400CXW100MEFC18X25 has a number of unique features and stands out among other electrolytic capacitors. Firstly, the 400CXW100MEFC18X25 has a much higher capacitance rating compared to other aluminum electrolytic capacitor models. The main reason behind this is the way the electrodes are made from aluminum which is being anodized to form a dielectric layer which increases its surface area and thus providing a much higher capacitance density. Furthermore, the 400CXW100MEFC18X25 provides an extended temperature range when compared to other electrolytic capacitor models.

The working principal of the 400CXW100MEFC18X25 is quite simple. When electricity is applied through the anode and cathode terminals, electrons and ions move between the two and create an electrostatic field between them which is proportional to the applied voltage. The 400CXW100MEFC18X25 also has a low ESR or equivalent series resistance, which is the resistance of the electrical connection between the anode and the cathode terminals. The effect of this is that the capacitor stores more energy for the same applied voltage as the ESR is very low, thus providing a greater storage capacity.

Applications of 400CXW100MEFC18X25 Capacitors

As stated above, due to its high capacitance density and low ESR, 400CXW100MEFC18X25 capacitors are perfect for power back-up applications. This is mainly because they can store a lot of energy in a small form factor, which makes them ideal for applications such as laptop computers and mobile phones that require power back-up. Additionally, 400CXW100MEFC18X25 capacitors are also frequently used in high power audio amplifiers, automotive circuits, and audio crossover and switching applications.

Additionally, due to the extended temperature range and high ripple current capabilities of the 400CXW100MEFC18X25, they are also widely used in other industries such as industrial control systems, aerospace and aviation, telecommunication, and medical equipment. The 400CXW100MEFC18X25 capacitors offer an extensive performance range and are capable of meeting most industry standards and applications.

Conclusion

The 400CXW100MEFC18X25 capacitors are a perfect example of aluminum electrolytic capacitors, and the fact that they are so versatile makes them very attractive to a variety of industries. Whilst the working principal of the 400CXW100MEFC18X25 is relatively simple, the resulting combination of features makes it ideal for a variety of applications and makes them a popular choice for design engineers.
