Aluminum electrolytic capacitors are the most widely used and common capacitor in the world in all aspects including cost, performance, and frequency response.The EEE-FC1E220P is an aluminum electrolytic capacitor with a large capacitance and range of features, making it ideal for a number of power electronics applications. This article will discuss the application field and working principle of EEE-FC1E220P.

Application Field

The EEE-FC1E220P is a high-value aluminum electrolytic capacitor featuring an extended capacitance range with a significant amount of ripple current capability. This makes the EEE-FC1E220P well-suited for a number of power electronics applications. It can be used in high-frequency switching applications, including switching mode power supplies (SMPS) and other high-frequency converters. Additionally, the EEE-FC1E220P is often selected for use in high-current UPS systems, audio power amplifiers, and solar cell inverters.

Working Principle

Aluminum electrolytic capacitors are constructed with two layers of aluminum foil separated by an insulating material, called the dielectric. Electrolyte is added to the gap between the two layers to form an electrical link between them. The electrolyte is either a liquid, solid or a combination of the two. The electrolyte helps to form an oxide layer on the aluminium foil, thereby increasing the capacitance and allowing the capacitor to store more energy. The EEE-FC1E220P uses an extended capacitance range through a multi-level construction design, which enables the capacitor to store more energy.

The EEE-FC1E220P also features a low Equivalent Series Resistance (ESR) and good ripple current ratings up to 3750 µA, which helps to minimize high frequency losses and enable higher output currents. This is important for power electronics applications due to the high frequency switching nature of these applications, where losses need to be kept as low as possible. Additionally, the EEE-FC1E220P has a long life expectancy, up to 10,000 hours, due to its low ESR and low leakage current.

In conclusion, the EEE-FC1E220P is an excellent choice for high-frequency power electronics applications and other applications requiring high ripple current capabilities and excellent capacitor life expectancy. The extended capacitance range and low ESR enable high efficiency and low losses, while the long life expectancy makes it an ideal solution for long term operation.
