Aluminum Electrolytic Capacitors: UPM1A182MHD1TO Application Field and Working Principle

Aluminum Electrolytic Capacitors are a type of capacitor made with a solid aluminum oxide film as the dielectric layer. This dielectric layer can provide very high capacitance values in a very small footprint, allowing them to be used in high density applications such as laptop motherboards and computer memory. The UPM1A182MHD1TO capacitors are miniature Aluminum Electrolytic Capacitors from Panasonic that offer excellent performance in demanding applications.

UPM1A182MHD1TO Feature

UPM1A182MHD1TO capacitors are small in size, yet possess superior performance due to their snap-through construction. The snap-through construction consists of a dielectric film, folded capacitors, and high-saturated electrolyte. The folded capacitors help to reduce the size, while the electrolyte provides maximum energy storage with excellent dissipation. These capacitors are also ideal for applications with high ripple current, high ESR, and a long life span. The UPM1A182MHD1TO also offer an operating temperature range of -55C to +105C, making them suitable for both commercial and industrial applications.

Applications of UPM1A182MHD1TO

Due to their small size, which makes them ideal for high density applications, UPM1A182MHD1TO capacitors are commonly used in the following applications:

• · Computers and peripherals
• · TVs and audio equipment
• · Cellular phones and PDA’s
• · Automotive electronics
• · Digital cameras and camcorders

Working Principle of UPM1A182MHD1TO

The UPM1A182MHD1TO capacitors use aluminum oxide as their dielectric layer. This layer allows the capacitor to store and release charge, which then causes a current to flow. Charges are stored and released by the capacitor when it is connected to the circuit in such a way that the positive charge is drawn towards the positive electrode, and the negative charge is drawn towards the negative electrode. During this process, the electrons and ions in the aluminum oxide layer start to move in different directions, leading to the formation of an electrical field in the form of an electric double layer. This electric double layer generates a capacitance, which is measured by the capacitance value of the capacitor.

Conclusion

UPM1A182MHD1TO capacitors are an excellent choice for high density applications due to their small size, high capacitance value, and excellent performance. These capacitors are capable of handling high ripple current, high ESR, and a long life span as well. They are suitable for use in a variety of applications, such as computers and peripherals, TVs and audio equipment, cellular phones and PDA’s, automotive electronics, and digital cameras and camcorders. The working principle of UPM1A182MHD1TO capacitors is based on the formation of an electric double layer in the aluminum oxide layer, leading to the generation of capacitance.
