Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors whose anode electrode is made of a pure aluminum foil with an oxidized surface. This oxidized surface acts as the dielectric of the capacitor, and the layer of aluminum oxide acts as a sealant to protect the material inside the capacitor. The SLPX222M180H7P3 aluminum electrolytic capacitor is a popular product in this category of capacitors, which finds multiple applications in many industries.

Application Field

The SLPX222M180H7P3 aluminum electrolytic capacitor offers high reliability, low leakage current, high volumetric efficiency and long-term stability. It can operate within -40 to +105 degrees Celsius. With these essential properties and characteristics, it has a wide range of applications in automotive (even at high temperatures), in the oil and gas industry, in telecommunications, consumer electronics and many other industries.

The main usage of aluminum electrolytic capacitors is in the power-supply decoupling. They are used as coupling capacitors between two amplifying stages, as well as DC blocking capacitors in audio applications. SLPX222M180H7P3 aluminum electrolytic capacitors are primarily used in military, aerospace, medical equipment, and industrial equipment. In industrial equipment, they are used as drivers in computer networks, motor drive, industrial automation, factory automation, motor control, and lighting control.

Working Principle

Aluminum electrolytic capacitors are polar capacitors that have a much larger capacitance per volume than conventional capacitors. This higher capacitance is achieved by forming an oxide layer on the anode that acts as the dielectric for the capacitor. This layer is formed by passing an electrical current through the electrolyte. The electrolyte then forms a thin layer between the anode and the cathode. This layer is the dielectric for the capacitor.

The minimum voltage and maximum peak current rating of the SLPX222M180H7P3 are 4.0 VDC (Voltage Reference) and 1.0 A (Current Reference), respectively. The high ripple current capability of the SLPX222M180H7P3 makes it suitable for high-performance applications, such as high-frequency switching power supplies, motor drives, and DC-DC converters.

Aluminum electrolytic capacitors are usually moisture proof and more temperature resilient than other capacitors. They are also known for their long life expectancy, which makes them a preferred option compared to other types of capacitors. For further improvements in reliability and performance, capacitor vendors have offered an X resistor with the SLPX222M180H7P3, which reduces the dielectric absorption by almost 50%.

Conclusion

The SLPX222M180H7P3 aluminum electrolytic capacitor is a highly reliable device used for many applications across different industries. It has a wide temperature range, high volumetric efficiency, and long-term stability. It is an ideal choice for motor drives, high-frequency switching power supplies, and DC-DC converters. Aluminium electrolytic capacitors are a reliable and cost effective choice in many applications, and with the X resistor, these capacitors can offer even better performance.
