Aluminum electrolytic capacitors are an integral component of many electronic or electrical systems due to the large capacitance they can achieve in relatively small sizes. These components widely used across multiple industries, from automotive to consumer electronics, cover multiple products such as power supplies, displays, and even computers. One such capacitor is the 226AVD050MER, which is a radial leaded aluminum electrolytic capacitor.

The 226AVD050MER is an aluminum electrolytic capacitor that has a nominal capacitance of 0.01µF (10,000pF). It is a non-polarized capacitor and features an operating temperature range from -55°C (-67°F) to +105°C (+221°F). As previously mentioned, it is a radial leaded aluminum electrolytic capacitor, meaning that it is cylindrical in shape with leads coming out of its sides, instead of out of the top and bottom like with axial leaded types.

The 226AVD050MER is often used in automotive and consumer electrical applications, due to its high temperature and voltage ratings. These include voltage regulators in computers, decoupling and filtering capacitors in circuits, and even time delays in automotive components. As its inductance is low, with minimal resistance it is able to pass rapid pulses without distortion.

The 226AVD050MER’s working principle is based on the fact that when the positive and negative charges of two electrodes are separated, they create an opposite voltage between them. This effect is known as a dielectric effect, and the charges are commonly created by an electrolyte solution between the capacitor’s two electrodes. This creates two capacitors out of the one unit, one for each plate doing the charge separation.

In the226AVD050MER, the electrolyte is made up of an organic solvent and a metal oxide (typically manganese dioxide), and the charged plates are made of an aluminum foil that has been chemically etched to create a fine pattern. As the electrolyte passes through the etched aluminum plates, an electrolytic effect happens. This effect helps to increase the capacitance stored within in the electrolyte to give the capacitor a greater capacitance.

The capacitance of a capacitor is determined by the area of the two electrodes and the dielectric between them. The thicker the layers of the plates, the higher capacitance of each capacitor created. This is why capacitors made with aluminum foil have such a high magnitude of capacitance.

The 226AVD050MER is an ideal capacitor to use when a high voltage rating and low leakage current is needed. It is a popular choice for many applications due to its low size, high temperature and voltage ratings, and low inductance. Its working principle based on the dielectric effect of an electrolyte helps to ensure its capability to store large capacitance in relatively small sizes.
