Aluminum electrolytic capacitors are a type of capacitors widely used in electronic circuits for their low cost and very high capacitance values per unit volume. The model 101C702U050AA2A that we will analyze is no exception. Let\'s take a look at its application field and working principle.

Aluminium electrolytic capacitors belong to a group of capacitors called polarised capacitors, as they can only be connected one way up, because internally they include a chemical called electrolyte. This consists of a liquid or paste capable of conducting electricity, so that a current can flow from the anode to the capacitor’s shell. This means that the electrolyte serves as the electrical connection between the capacitor’s anode and the shell, which are both made of aluminium.

The 101C702U050AA2A model belongs to the series of high voltage capacitors composed by six different capacitors. Its maximum rated voltage is 100 volts DC and its maximum capacitance value is 2.2 μF. This means that this model is specially suitable to be used in power supply stages or energy- loading applications.

Now we are going to take a look at its construction and working principle in order to understand why this model is so useful in power supply stages and energy- loading applications. The capacitor’s structure consist of two aluminium foils as electrodes, where the positive foil is treated with an anodic oxidation layer and the electrolyte provides the connection between the anode and the cathode. The capacitor’s dielectric is composed of an oxide layer formed on the anodic oxidation layer. As electrons flow, this oxide layer traps and builds up the charge.

When a powered device is connected to a 101C702U050AA2A capacitor, the device uses this capacitor\'s stored energy by drawing current through the electric circuit. This process causes the electrons to leave the positively charged anode, passing through the electrolyte and cross the oxide layer to the negatively charged cathode, that acts as a collector.

In power supply stages, because these capacitors can store and release a considerable amount of energy, they can prevent voltage drops in case of intense current peaks. Generally, the more capacitors in the circuit, the more energy can be stored.

The 101C702U050AA2A capacitors also can be used in energy-loading applications. In such circuits, they behave like energy reservoirs. In other words, when the power is turned off, the capacitors acts as a source of energy, releasing the stored energy in the circuit. This allows the circuit to keep running for a while until the energy stored in the capacitors is completely depleted.

In summary, the 101C702U050AA2A model of aluminium electrolytic capacitors is specially suitable for power supply stages and energy- loading applications. This is mainly because of their ability to store and release a considerable amount of energy. Furthermore, their ability to prevent voltage drops in case of intense current peaks can be very useful.
