Aluminum Electrolytic Capacitors, also known as Aluminum Electrochemical Capacitors, are used in high frequency and high temperature applications. They are widely used in various fields, especially for their ability to easily store energy and for their long lifespan. The URZ1H4R7MDD, in particular, is a popular model among all types of aluminum electrolytic capacitors, due to its high performance and reliability.

The structure of this capacitor consists of aluminium foil, paper separator and electrolyte. The aluminium foils are used as electrodes which are electronically connected to the external circuit. The paper separator is used to prevent the leakage between the aluminium foil and electrolyte and to keep the electrolyte in uniform. The electrolyte functions as a medium to transport the charge carriers.

The working principle of the URZ1H4R7MDD aluminum electrolytic capacitor is as following. When a DC voltage is applied to the capacitor, the positive charges move to the anode and the negative charges move to the cathode. The aluminum foil anode acts as a source of these charges; plus, it also provides the electric field that helps to keep the charges in the capacitor. At the same time, the electrolyte functions as the medium for the charges to pass through. This sets up an electric field in the capacitor, which creates an electrochemical reaction between the two foils.

When the capacitor is in operation, the electric field created by the DC voltage causes the migration of charge carriers between the anode and the cathode. This in turn creates a voltage across the capacitor that is proportional to the applied DC voltage. The resulting charge accumulated on either side of the capacitor creates a storage effect, which is what stores energy in the capacitor.

In high frequency applications, the URZ1H4R7MDD aluminum electrolytic capacitors can be used in pulsed-mode operation to provide stable operation in high temperatures. During its operation, the capacitor maintains its high capacitance while disregarding the influence of frequency. This makes the URZ1H4R7MDD an ideal choice for high power applications such as power supply units and automotive electronics.

Thanks to its ability to easily store energy, the URZ1H4R7MDD aluminum electrolytic capacitors are widely used in various applications, from consumer electronics and appliances to industrial equipment and products. It is a reliable and cost-effective solution for various applications that require high frequency or high temperature working conditions.
