Introduction

Aluminum electrolytic capacitors (also called electrolytic caps or aluminum electrolytics) are a type of capacitor that utilizes an electrolyte solution to store energy in the form of an electric field. Aluminum electrolytics are widely used in a variety of applications, from small cellphone designs to large commercial equipment. Many of these electrolytic capacitors, including the UBW1H471MHD, are designed with a specific purpose in mind and features unique properties that make them useful in the intended application.

Capacitance

The UBW1H471MHD capacitors have a rated capacitance of 470uF to meet the power requirements of many applications. This makes it a suitable choice for automotive, control, and consumer electronics applications. The tolerance for these capacitors is ±20% at 120 Hz, +50°C, making them very accurate in terms of performance.

Ripple Current

The UBW1H471MHD capacitors feature a high ripple current rating of 1.1 Á** 2 kF, making them suitable for designs that require a high level of current handling capability. This allows the capacitors to be used in applications that handle higher levels of current such as power supplies or high-end audio amplifiers. Furthermore, the capacitors are rated for an operating temperature of up to +105°C, making them suitable for use in hotter environments.

Case Type

The UBW1H471MHD capacitors have a cylindrical aluminum case with dimensions of 10 mm (diameter) x 10 mm (height) and are RoHS compliant. This makes them easy to integrate into designs with little or no modifications. The capacitors are rated for an applied voltage of up to 50 VDC.

Applications

The UBW1H471MHD capacitors are suitable for a wide variety of applications, including but not limited to: automotive, control, consumer electronics, power supplies, and high-end audio amplifiers. The capacitors have a high ripple current rating which makes them suitable for applications that require a high level of current handling capability. The capacitors can also be used in hot environments due to their rated operating temperature of up to +105°C.

Working Principle

The UBW1H471MHD capacitors use an electrolyte to store energy in the form of an electric field. When an electric charge is applied to the electrolyte, it forms a polarized field. This polarized field strength increases as the voltage increases, allowing the capacitor to store more energy. Aluminum electrolytics are advantageous due to their high ripple current rating, large capacitance values, and relatively low cost compared to other types of capacitors.

Conclusion

The UBW1H471MHD capacitors are a versatile and efficient type of aluminum electrolytic capacitor well suited for many applications. The capacitors feature a high ripple current rating of 1.1Á**2kF, making them suitable for applications that require a high level of current handling capability. The capacitors also feature a rated capacitance of 470uF and are rated for an operating temperature of up to +105°C, making them an ideal choice for automotive, control, and consumer electronics designs. Furthermore, the UBW1H471MHD capacitors are RoHS compliant and have a cylindrical aluminum case with dimensions of 10mm (diameter) x 10mm (height), making them easy to integrate into designs with little or no modifications. In summary, the UBW1H471MHD capacitors provide an excellent way to store electrical energy for various applications.
