Aluminum electrolytic capacitors are electronic components used in the signal transmission and filtering of electronic devices.

The EEU-HD1V681B is an aluminum electrolytic capacitor specifically designed as a power supply filter capacitor. The EEU-HD1V681B is a relatively large capacitance aluminum electrolytic capacitor with a rated voltage of 400V and a maximum capacitance of 680uF. Its ultimate characteristics and filtering effects are particularly suitable for high power filter outputs. Its features include low impedance, large capacity, and excellent ripple current capability.

The EEU-HD1V681B is widely used in the power supply of electronic equipment, especially in the power supply (such as uninterruptible power supply) and high-frequency LED switch power supply. It is also widely used in power filter circuits, electronic ballast, frequency conversion, digital circuits, audio equipment and other fields. The working principle of aluminum electrolytic capacitor is based on the movement of ions in a salt-based solution. The current ions pass through the electrolyte, and the charge separation forms a differential voltage between the two sides of the electrolyte.

The EEU-HD1V681B\'s metalized aluminum foil is wound in a spiral shape and is extruded in an integrated aluminum outer shell. The electrolyte enters the aluminum foil wound in a spiral shape, and two separate charging surfaces are formed inside and outside. Electrolyte acts as a medium to connect two separate charging surfaces. The metal foil is the anode, and the outer shell and exit when the electric current passes through the electrolyte.

The EEU-HD1V681B aluminum electrolytic capacitor has both capacitor and resistive functions. Its capacitance is proportional to the area of the foil billet, and its resistance is proportional to the thickness of the electrolyte layer on the aluminum foil surface and the distance between the two billet surfaces. Through this design, the EEU-HD1V681B has a low internal resistance, good frequency characteristics, high capacitance and excellent low-frequency audio distortion performance, making it ideal for use in high power filter output applications.

No matter what type of aluminum electrolytic capacitor is used, the core elements including electrolytes, electrodes, foils, shells and insulating materials remain the same. In the development and production of aluminum electrolytic capacitors, continuous innovation is needed to maintain a good product performance and quality.
