Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in modern electronic devices providing both electrical energy storage and DC power-line filtering functions. They are an integral part of the power supply of virtually every laptop, smartphone and desktop computer, found in industrial automation systems and process controllers. As the name implies, they consist of an anode made of aluminum, a dielectric of an electrolyte solution or gel, and a cathode in the form of a metal foil.

63ZLH560MEFC12.5X30

The 63ZLH560MEFC12.5X30 is a general purpose, radial lead aluminum electrolytic capacitor that is designed for use in many power electronics applications. Its ratings are as follows: voltage rating: 50 VDC; capacitance: 560µF ±20%; ESR: 0.050Ohm max; temperature range: -40°C to 85°C; and lead spacing of 12.5mm. Featuring a molded polypropylene dielectric, this capacitor provides superior performance in a wide range of temperatures.

Application Field

The 63ZLH560MEFC12.5X30 aluminum electrolytic capacitor is usually used in power supply units, DC/DC converters, line feed filters, TV receivers and other electronic equipment for blocking, bypassing, filtering, coupling and decoupling. It can also be used for timing and energy storage functions in electronic products.

Working Principle

The 63ZLH560MEFC12.5X30 aluminum electrolytic capacitor operates on the basic principle of an ideal capacitor, where the capacitance of a capacitor is the ratio between the charge stored in the capacitor\'s plates and the potential difference applied between them. In aluminum electrolytic capacitors, the capacitance is increased using a dielectric layer consisting of a thin layer of oxide on the surface of the aluminum foil. The oxide forms an insulating layer which effectively multiplies the surface area of the plates and thus increases the capacitance.

The dielectric layer of the 63ZLH560MEFC12.5X30 is formed by a thin, self-formed layer of aluminum oxide, usually created by passing a current through the capacitor. Thus, this type of capacitor is known as an ‘electrolytic’ capacitor and can store significantly larger voltages and currents than a regular non-polarized capacitor due to the larger surface area of the plates and the thickness of the dielectric layer.

In addition, this type of capacitor typically also has an extremely low equivalent series resistance and thus provides superior performance properties in terms of noise suppression, filtering and power storage.

Conclusion

The 63ZLH560 MEFC12.5X30 aluminum electrolytic capacitor is an ideal choice for applications such as power supplies, DC/DC converters, line feed filters, TV receivers and other electronic equipment. Its low equivalent series resistance, superior temperature range and large capacitance rating make it a great choice for power electronics applications.
