EEV-HA1C331UP

Aluminum electrolytic capacitors are widely used in various fields due to their characteristics of large capacitance, small size and low volume. EEV-HA1C331UP is one of the aluminum electrolytic capacitors which has a wide range of application fields and has many unique working principles.

Application Field

EEV-HA1C331UP is a radial aluminum electrolytic capacitor with a good reliability. It is mainly used in avionics, communications and other instruments, as well as power supplies and other circuits. Its maximum operating temperature is 105℃ and rated voltage is 250V. Meanwhile, it has good self-healing properties and high working frequency.

Working Principle

The principle of the EEV-HA1C331UP aluminum electrolytic capacitor is based on Faraday\'s law. When AC current flows through the capacitor, AC electrostatic field is generated. At the same time, the electrolyte of the capacitor also enables a thin oxide layer on the surface of the aluminum foil electrode to form a capacitor dielectric. This thin dielectric layer has high dielectric constant and low dissipation factor, which can effectively increase the current carrying capacity of the capacitor.

EEV-HA1C331UP also has a self-healing system that can automatically detect and remove the breakdown residues generated on the dielectric when it fails due to breakdown caused by voltage or temperature. When the voltage is restored to its normal voltage, the capacitor is still working, because the thin insulating film composed of electrolyte and oxide layer is re-formed during the self-healing process. During the self-healing process, the capacitor is able to bear any load and has great reliability.

Conclusion

To sum up, EEV-HA1C331UP is an aluminum electrolytic capacitor which has wide application fields and unique working principle. It has high dielectric constant, low dissipation factor, good self-healing property, high working frequency and can withstand any load when it works, which makes it suitable for use in avionics, communications, instrumentation, power supply and other circuits.
