Aluminum electrolytic capacitors are commonly used in a wide variety of applications due to their small size, large capacitance and reliable performance. The EEE-HBV101UAP is a high volumetric efficiency wet aluminum electrolytic capacitor with a capacitance range of 100 to 1000 μF and a working voltage range of 50 to 500 VDC. This capacitor is designed for application in power electronic circuits, such as voltage regulators and DC-DC converters, where high ripple current and low ESR is required.

The capacitance of an aluminum electrolytic capacitor is determined by its size and the surface area of its electrodes. The EEE-HBV101UAP capacitor is a radial lead device that uses a special process to maximize the surface area of its aluminum electrolyte electrodes. This gives the EEE-HBV101UAP capacitor its high volumetric efficiency, which is the ratio of capacitor volume to total capacitance value. The special surface area of the aluminum electrolyte electrodes also contributes to its low-ESR characteristic and high ripple current handling.

The construction of the EEE-HBV101UAP capacitor consists of two electrodes, an aluminum anode and a cathode foil, that are wrapped around a porous paper separator which is soaked in an electrolyte. The aluminum anode is formed using a laser-etched aluminum foil and an activated aluminum oxide layer to maximize its surface area. The cathode foil is composed of an electrically conductive media saturated with electrolyte and is connected to the common ground. The two electrodes are connected in series forming a circuit that stores energy.

The working principle of the EEE-HBV101UAP is based on the property of the electrolyte separating the two electrodes. When voltage is applied across the electrodes, ions from the electrolyte move through the separator and provide a conducting path for current to flow. This current creates an electrical field between the two electrodes which is stored as an energy charge. When the voltage is removed, the energy stored as an electrical field remains stored and helps to dissipate any transient voltages when the capacitor is discharged.

The high volumetric efficiency, low-ESR and high ripple current capability of the EEE-HBV101UAP make it the ideal choice for use in various applications such as voltage regulators, converters, and DC-DC switch mode power supplies (SMPS). The capacitor is designed to withstand temperature ranges of -40 to +105 °C and has a rated life of 1000 h at rated working voltage and +105 °C.

In conclusion, the EEE-HBV101UAP is a robust, high performance aluminum electrolytic capacitor with a wide range of applications. Its high volumetric efficiency, low-ESR and high ripple current capability make it an ideal choice for power electronic circuits in various applications.
