Aluminum Electrolytic Capacitors

The 516D478M010QS6AE3 is an aluminium electrolytic capacitor. It is a polarized capacitor with a device constructed of two aluminum foils coated with an insulating oxide layer and wound together with electrolyte paper soaked in electrolyte acting as the dielectric. It is widely used in the design of numerous electronic circuits, such as AC adapters, dc power supplies, communication systems, and radios.

Application Field

An aluminium electrolytic capacitor is an ideal choice for applications such as DC-DC converters, power management circuits, inverters, and high-speed switching circuits. It can also be used to reduce high-frequency noise, provide high capacitance at low voltage levels, and as a power supply filter. In addition, electrolytic capacitors are used to bypass voltages in radio and audio circuits to reduce hums and buzzes caused by power supply fluctuations.

Aluminum electrolytic capacitors are often used in Timing Circuits, which are used to manage time in a circuit, such as generating oscillation of a given frequency or to provide a time-delay in signal processing. They are typically used in timer applications like clock generation, frequency division, pulse stretching and pulse width modulation. Electrolytic capacitors are also useful in radio frequency circuits and high frequency oscillators, where a good dielectric is necessary.

Working Principle

An electrolytic capacitor is a type of capacitor design which uses an electrically-conductive liquid or gel-like material, known as an electrolyte, between two electrodes. The electrolyte consists of a positively charged anion and a negatively charged cation. When a voltage is applied between the two electrodes, an electric field is created in the electrolyte. This electric field induces a charge movement from the anode to the cathode, resulting in a relatively large capacitance.

The electrolyte also allows the capacitor to withstand higher voltages than other types of capacitors, without losing capacitance, as it does not break down at high voltages like dielectric insulating substances. Additionally, they are typically much higher in capacitance than other types of capacitors, making them ideal for applications where high capacitance at low voltage levels is a must.

The two aluminum plates of an electrolytic capacitor are typically wound together in order to increase the surface area of the electrodes and thus increase the capacitance of the capacitor. Furthermore, an insulating oxide layer is coated on the aluminum plates in order to prevent electrical shorting. This oxide layer also helps to reduce the ESR (Equivalent Series Resistance) of the capacitor, thus increasing its efficiency.

In summary, the 516D478M010QS6AE3 is an aluminum electrolytic capacitor with a large capacitance and high reliability. It is an ideal choice for applications where high capacitance at low voltage levels is a must, such as DC-DC converters, power management circuits, and inverters. It is also useful in radio frequency and high frequency oscillators, allowing for a good dielectric and reducing hums and buzzes caused by power supply fluctuations.
