227CKE100MNU

Aluminum electrolytic capacitors are widely used in a variety of applications due to their low cost, availability and long life expectancy. Among them, 227CKE100MNU is a popular type of aluminum electrolytic capacitor which has relatively high voltage and large capacity, so it can be used in many kinds of circuits, especially in high frequency circuits.

227CKE100MNU Application Field

As mentioned above, 227CKE100MNU aluminum electrolytic capacitors are generally applied in high frequency circuits, where they are employed as charge and discharge capacitors to buffer the voltage spikes. Owing to their high voltage and large capacitance, 227CKE100MNU aluminum electrolytic capacitors are also utilized in power supplies, MOSFET gate drivers, analog filters, DC-DC converters, switching regulators and load dedicated circuits in communications and computer systems. Besides these, 227CKE100MNU aluminum electrolytic capacitors can also be applied in board-level coupling, decoupling, and DC blocking applications.

227CKE100MNU Working Principle

227CKE100MNU Aluminum Electrolytic Capacitors are based on a modified electrolyte solution, which is then sealed with a glass-to-metal seal to place the anode and cathode plates in close proximity. The anode and cathode of 227CKE100MNU aluminum electrolytic capacitors are polarized, with the anode being the positive terminal, and the cathode being the negative terminal. Furthermore, the anode surface is chemically treated as anodic activation so that it can more easily absorb ions. When voltage is charged to the terminals of 227CKE100MNU aluminum electrolytic capacitors, aluminum oxide is formed on the anode’s surface, leading to a decrease of capacitance.

In order to absorb greater amounts of electrons when voltage is applied, 227CKE100MNU aluminum electrolytic capacitors have a larger plate area than standard electrolytic capacitors. Additionally, the polarization of the cathode plate further enhances the capacitor’s charge and discharge performances. In contrast to other types of capacitors, 227CKE100MNU aluminum electrolytic capacitors employ ceramic capacitors in their design for better temperature characteristics and stability.

In conclusion, 227CKE100MNU aluminum electrolytic capacitors are frequently used in various applications due to their high voltage and large capacity characteristics. They are especially suitable for high frequency circuits such as MOSFET gate drivers, analog filters, and DC-DC converters. Although 227CKE100MNU aluminum electrolytic capacitors have the disadvantage of a capacitance decrease with voltage applied, they are still used due to their long life expectancy and cost effectiveness.
