EEE-HC1A221P

Aluminum electrolytic capacitors are one of the most important components in electrical systems today. There are many different types of aluminum electrolytic capacitors available, but the EEE-HC1A221P is one of the most popular. This capacitor is used in a wide range of applications, such as power supplies, digital electronics, and high-frequency circuits. In this article, we will discuss the application field and working principle of the EEE-HC1A221P.

The EEE-HC1A221P is a type of radial aluminum electrolytic capacitor. It is designed for use in high-temperature and high-frequency environments, such as those encountered in power supplies. It is characterized by its small size, large capacity, and low equivalent series resistance (ESR). It has a typical capacitance of 220µF at 85℃, with a minimum of 200µF, and a maximum of 300µF. The rated voltage for this capacitor is 100, 125, or 160V DC.

The aluminum electrolytic capacitor works on the principle of electrolytic double layer capacitance. This occurs when a voltage is applied between the two electrodes of the capacitor and the electrode surfaces become polarized. When a potential difference is applied to the electrodes, an electric field is created that causes the positive charge to migrate toward the negative electrode, while the negative charge migrates toward the positive electrode. A film of non-conductive aluminum oxide is formed on the electrodes, which acts as the dielectric material between them, allowing a charge to build up on either side. This stored charge creates an electric field that provides the capacitor’s capacitance. The higher the voltage applied to the capacitor, the more charge it can hold, and the greater the capacitance.

The EEE-HC1A221P is commonly used in power supplies, digital electronics, and high-frequency circuits. It is also used to filter signals that carry a high-frequency. The capacitor can be used with other components, such as inductors, to create a low pass filter. The EEE-HC1A221P can be used in power factor correction circuits, which are used to reduce the harmonic distortion caused by inductive loads. It can also be used in snubber circuits, where it reduces voltage spikes created by switching circuits.

The EEE-HC1A221P has a recommended application temperature range of -55℃ to +125℃. It is rated for an operational life of 2000 to 5000 hours at a temperature of +85℃. It also has an expected life of 10 years or 20000 to 50000 hours at +20℃. It is important to note that these are rated times, not necessarily the actual life of the capacitor. Care should be taken when choosing the EEE-HC1A221P for specific applications.

In conclusion, the EEE-HC1A221P is a type of radial aluminum electrolytic capacitor which is used in high-temperature and high-frequency environments. It works on the principle of electrolytic double layer capacitance and is commonly used in power supplies, digital electronics, and high-frequency circuits. The capacitor is rated for an operational life of 2000 to 5000 hours at a temperature of +85℃, and 10 years or 20000 to 50000 hours at +20℃. Care should be taken when choosing the EEE-HC1A221P for specific applications.
