Aluminum electrolytic capacitors are one of the most common types of capacitors used in electronic devices. Their capability of offering a high capacitance size to volume ratio makes them particularly useful in power electronics as they are able to store high levels of electrical energy in a comparatively smaller size. UPM2A2R2MDD1TA aluminum electrolytic capacitors are particularly well suited to applications which require highly reliable and long life capacitors.

UPM2A2R2MDD1TA aluminum electrolytic capacitors are cylindrical in shape and are designed to handle an operating voltage of 55 Volts (V) which makes them suitable for use in power circuits, audio and filtering applications. They offer low Equivalent Series Resistance (ESR) ratings which is beneficial for applications requiring optimal AC performance as it reduces power supply ripple noise caused by ESR fluctuations. They possess an Electrolytic Polarized Capacitance (EPC) rating of 2.2 milliFarads (mF) and a Dielectric Strength of 35 Volts (V).

The working principle of the UPM2A2R2MDD1TA aluminum electrolytic capacitors is based on chemical-electrical reaction. Two metal plates – one aluminum and the other a foil – are connected together in an anode and a cathode arrangement. The aluminum plate is the anode and the foil plate is the cathode. The interior of the capacitor is filled with an electrolytic material -typically composed of a mixture of organic solvents and an ionic solute, such as salt – which acts as the dielectric material between the two plates. Lastly, a sealant is used to maintain the integrity of the capacitor over its operating life.

When the capacitor is charged, electrons are attracted to the negatively-charged cathode foil and the positive charge is stored by the anode plate. The electrolytic material between the two plates enables current to move back and forth between the two plates, which is the basis for capacitance. Every time the voltage applied to the plates increases, an increase in capacitance is observed, although the maximum capacitance attainable is still limited by the size of the device.

In conclusion, UPM2A2R2MDD1TA Aluminum Electrolytic Capacitors offer high capacitance size to volume ratio and are particularly well suited to applications which require highly reliable and long life capacitors. They are commonly used in audio, filtering, and power circuits for their low equivalent series resistance (ESR) rating and dielectric strength of 35 Volts (V). Their working principle is based on a chemical-electrical reaction between an anode aluminum plate, a cathode foil plate, and a dielectric electrolytic material.
