Aluminum electrolytic capacitors, often simply called electrolytic capacitors, are polarization-dependent capacitors which use an insulating aluminum oxide layer as the dielectric. They are the only type of capacitor available with capacitance values in the thousands of microfarads and therefore are popular for energy storage applications. The UPB1HR47MDD1TA is a popular aluminum electrolytic capacitor used in a variety of electrical and electronic devices.

The UPB1HR47MDD1TA is a high voltage aluminum electrolytic capacitor with a maximum working voltage of 400V and a rated capacitance of 470000μF. It is a radial leaded non-solid electrolytic capacitor that can self-heal under high reverse voltage. It is ideal for power supply smoothing and filtering, LED backlighting, industrial inverters, switching power supplies, and other high voltage applications. These capacitors use a sintered anode and a manganese dioxide cathode, and are suitable for high frequency applications and high temperature environments.

The UPB1HR47MDD1TA is an electrolytic capacitor with a two-pin construction. It has two leads on opposite sides of the capacitor, each connected to one side of the main capacitor winding. The two leads are copper-tungsten alloy with silver plated ends. The capacitor\'s body is made from an aluminum casing with a plastic base and three holes. The core of the capacitor is an anode of sintered aluminum foil, sandwiched between two layers of manganese dioxide and filled with electrolyte. The capacitor\'s dielectric is an insulating aluminum oxide layer.

The working principle of an aluminum electrolytic capacitor is based on the principle of electrochemical polarization. Electrolyte polarized by a metal oxide layer forms an excess of negative charge on one side, creating an internal electric field which, upon application of a reverse voltage, reduces the layer\'s resistance and increases the amount of current it can pass. This allows the capacitor to absorb a large amount of energy, and store it in the form of an electric charge. The capacitor can then be discharged, releasing the energy, in order to provide an output voltage.

The UPB1HR47MDD1TA is a robust and reliable capacitor that is well suited for high voltage applications. Its high capacitance and self-healing characteristics make it ideal for power supply applications and LED backlighting. It is also suitable for industrial inverters, switching power supplies, and other high voltage applications. The UPB1HR47MDD1TA can handle high temperatures and is suitable for both high and low frequency applications.
