Aluminum electrolytic capacitors are the electrical components widely used in electronic circuits for various purposes. They are constructed with two metal electrodes impregnated with an electrolyte, forming a pair of electrodes separated by an insulating film. The purpose of the aluminum electrolytic capacitor is to store and release electric energy in brief time intervals. EEV-HA1E330WR belongs to the aluminum electrolytic capacitors and its application field and working principle will be discussed in this article.

Application Field of EEV-HA1E330WR

EEV-HA1E330WR is an aluminum electrolytic capacitor with extended temperature range from -25°C to 105°C, and capacitance value of 330μF. It is capable of working with ripple current 2.2 times of its capacitance. Its application range includes, but not limited to the following:

• Automotive electronics, which need higher capacitance than ordinary electrolytic capacitors and require higher temperature range and ripple current.
• DC/DC converter for high-end computer, server, and network systems.
• Circuit of solar and wind power generation system.

Working Principle of EEV-HA1E330WR

The working principle of the EEV-HA1E330WR is based on the principle of electrochemical capacitance. It consists of two metallic plates immersed in an electrolytic solution such as salt water. The plates act as the electrodes while the solution acts as the dielectric. When a current is applied to the capacitor, ions from the electrolyte solution are attracted to one plate and repelled from the other, thus establishing an electrostatic field which stores the electrical energy. The ions essentially form an electric double layer, increasing the capacitance of the device. This is the working principle of the EEV-HA1E330WR.

Conclusion

EEV-HA1E330WR is one of the aluminum electrolytic capacitors whose application and working principle were discussed in this article. It is suitable for a variety of applications such as automotive electronics, DC/DC converter, and wind and solar power generation. The working principle of the capacitor is based on the electrochemical capacitance phenomenon, wherein ions from the electrolyte solution create a double layer capacitance, allowing it to store and release electric energy in brief time intervals.
