Aluminum electrolytic capacitors use the concept of electrolysis to store energy in a thin oxide layer created on an aluminum foil. This thin layer acts as the dielectric of the capacitor. The layer is extremely thin, usually on the order of 0.05 to 0.15 microns. The aluminum foil also serves as one of the plates. The other plate is generally a piece of paper, treated with a non-reactive coating such as acrylic or polyester, but other materials may be used depending on the application. The benefit of aluminum electrolytic capacitors is their low cost, large capacity, and wide temperature range.

381LX101M400H022 is an aluminum electrolytic capacitor that is widely used as power supply bypass capacitor in high frequency switching power supplies. This aluminum electrolytic capacitor has a maximum operating voltage of 400 volts, an operating temperature range of -55°C to + 85°C, and a capacitance of 1uF. It is designed for applications where high ripple current is a requirement, such as in electronic ballast, temperature controlled relays, motor drives, AC inverters, and power supplies. Its long life span makes it suitable for a variety of general-purpose industrial and commercial electronic equipment.

The working principle of 381LX101M400H022 capacitor is that when the electric field is strong enough, electrons will be drawn from the electrolyte onto the aluminum foil in order to balance the charge. This charge, which is stored as a potential difference between the aluminum foil and the electrolyte, is known as the capacitance of the capacitor. As the voltage across the capacitor increases, so does the capacitance. When the voltage is removed, the electrons return to the electrolyte and the charge is dissipated.

381LX101M400H022 aluminum electrolytic capacitors have several advantages over other types of capacitors when used in power supply bypass applications. First, its long life span, coupled with its high ripple current, ensures that it can handle high frequencies with minimal power loss. Second, its low ESR makes it ideal for applications where noise is a concern. Finally, its low capacitance variation over temperature ensures that it is able to deliver consistent performance regardless of ambient temperatures.

In conclusion, the 381LX101M400H022 aluminum electrolytic capacitor is a power supply bypass capacitor that can be used in many different applications. Its long life span, coupled with its low ESR, make it ideal for high frequency applications. Furthermore, its low capacitance variation over temperature ensures that it can handle applications that require consistent performance over wide temperature ranges. It is an excellent choice for high frequency switching power supplies, electronic ballast, temperature controlled relays, motor drives, AC inverters, and power supplies.
