Aluminum Electrolytic Capacitors (AECs) are polarized capacitors with large capacitance per volume. They have various applications, including smoothing, filtering, energy storage, and power conditioning. The UKL1HR33MDDANATA is an AEC designed with reverse voltage ratings of 275V and working temperatures of up to +125°C. It features low ESR, high ripple and long life. It is designed for use in automotive, industrial and consumer electronics.

The UKL1HR33MDDANATA is essentially two aluminum foil conductors that form a reverse-connected capacitor. The anode is made of aluminum foil coated with a resistive oxide layer. The oxide layer serves as a dielectric, providing insulation between the anode and the cathode, which is made of aluminum foil coated with a conductive material, referred to as the electrolyte. The electrolyte and the oxide layer form the AEC\'s capacitance.

When current is applied to an AEC, a voltage differential forms across the terminals. The voltage differential causes an electric field to develop between the anode and cathode, which sets up the capacitive properties of the AEC and allows it to store energy. The amount of energy stored is driven primarily by the AEC\'s capacitance and voltage rating. As the capacitance is increased and voltage rating is decreased, the energy stored increases. Conversely, when the capacitance is decreased and the voltage rating is increased, the energy stored decreases.

When an AEC is in use, current can flow through the electrolyte, causing charge carriers to move between the two electrodes. This process of charge transfer results in a capacitance that changes with the applied voltage. This is known as dynamic capacitance and it is a key feature of AECs. Therefore, when designing an application with AECs, it is important to take into account the effects of dynamic capacitance on the capacitance of the device.

The UKL1HR33MDDANATA is designed to provide superior performance and reliability.
