Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (AECs) are components with a wide range of applications in various industries, from small consumer electronics to complex industrial systems. AECs are divided into two major categories, electrolytic and non-electrolytic, and come in all shapes and sizes.

UPW2AR47MDD1TD application field and working principle

UPW2AR47MDD1TD is a polarized aluminum electrolytic capacitor, consisting of an anode made of aluminum foil, an electrolyte, a cathode foil, and a paper separator in between the anode and the cathode. The anode is coated with an activated oxide coating that serves as a dielectric. The cathode consists of aluminum foil and an inert metal like tin or nickel.

The electrolytic capacitor has a wide range of applications in various areas. In consumer electronics, the UPW2AR47MDD1TD is used as part of the power supply circuit, providing energy storage and regulation. In lighting systems, it is used to smooth out voltage and current spikes. In PLC and control systems, it is used as an energy storage device.

When the capacitor is connected to a circuit, the aluminum oxide layer serves as an insulator, preventing the direct flow of electric current between the electrodes. This allows the capacitor to store energy in the form of an electric field between the electrodes, like a battery. When a voltage is applied to the terminals of the capacitor, electric current flows from one electrode to the other, creating a charge and discharging energy.

When the capacitor is in use, it dissipates a certain amount of heat due to the losses of the dielectric material and of metal plates, so it is important to pay attention to the ambient temperature during operating and storing of the capacitors. In addition, due to the nature of these components, they should be handled with special care and not subjected to mechanical stress.

UPW2AR47MDD1TD is a good choice for applications where high capacitance, low ESR and operating temperature range are required. With these advantages, UPW2AR47MDD1TD can serve the wide range of applications from consumer electronics to industrial systems.
