Aluminum electrolytic capacitors are passive electronic components used for energy storage and filtering. The UPT2D271MHD6 is a type of aluminum electrolytic capacitor specifically designed for very high-frequency applications. This capacitor has a small size and can be soldered, which makes it an attractive choice for many applications.

Application Field

The UPT2D271MHD6 is a high-performance electrolytic capacitor used for high-frequency circuit applications, such as RF communication and cellular phone systems. Due to its small size and low inductance, it is well-suited for high-frequency circuit designs. It is widely used in cellular base stations, repeaters, and satellite communication devices.

The capacitor also has low ESR characteristics, making it suitable for power supply filters, digital filters, and power supply noise suppression. It is widely used in automotive and industrial applications, such as automotive ECUs, airbag systems, and industrial power supplies.

Working Principle

Like other aluminum electrolytic capacitors, the UPT2D271MHD6 is composed of an anode, a cathode, and a dielectric material. The positive electrode is made of aluminum foil, and the negative electrode is made of a carbon film. The dielectric material is an electrolyte, which is a mixture of water, ethanol, and dissolved potassium hydroxide .

When a voltage is applied to the capacitor, the electric field between the two electrodes attracts and repels electrons, resulting in a charge separation. As the capacitor is charged, the solution in the electrolyte starts to break down and the positive ions move towards the negative electrode, forming an electric double layer in the dielectric. This is where the energy and current is stored, allowing the capacitor to store charge over a long period of time.

The UPT2D271MHD6 is designed specifically for high-frequency applications, with an ESR of less than 0.2mΩ and a low inductance of 3nH. Its low ESR and low inductance make it an ideal choice for applications such as automotive electronics, RF communication systems, and industrial power supplies.

Conclusion

The UPT2D271MHD6 is a low-inductance high-frequency aluminum electrolytic capacitor. It is widely used in automotive and industrial applications, as well as in RF communication and cellular phone systems. Its small size and low ESR make it a suitable choice for many applications.
