SLPX821M220E5P3

Aluminum electrolytic capacitors are passive electronic components used to store and manage electronic energy. They are found in most modern electronics from consumer devices to industrial automation systems. The SLPX821M220E5P3 is a radial aluminum electrolytic capacitor used for power management and protections. In this article, we’ll take a look at its application fields and working principle.

Application Fields:

SLPX821M220E5P3 capacitors are widely used in electrical and electronic equipment such as TVs, mobile phones, computers, energy-saving luminous TV backlight power supply and other electronic products. They are also used in automotive ECU and automotive audio circuits, solar inverters, drone throttle controllers, and various types of motor control.

Working Principle:

The SLPX821M220E5P3 has a structure where a dielectric layer is sandwiched between two metal plates, an anode and a cathode. The anode is made of aluminum foil, while the cathode is composed of electrical glass structure paper and a liquid electrolyte. The anode is covered with a paste of a mixture of manganese and other metal oxides, and the plane of the anode is provided with a sintered part. This sintered part, with the aluminum as its skeleton, is not easy to deform, and has different contact performances on the surface. When AC power is applied to the capacitor, the anode reacts with the electrolyte through recombination and oxidation reactions. These cause electrons to flow within the device and current to pass through the device, which generates a voltage across the device. It has a characteristic of increasing capacitance value with a decrease in applied voltage.

Conclusion:

The SLPX821M220E5P3 is a radial aluminum electrolytic capacitor widely used in electric, electronic, automotive, and other equipment. Its application field covers a wide range from TVs, mobile phones to motors. This is due to its ability to store and manage electric energy, as well as pass a voltage through it, thanks to its recombination and oxidation reactions.
