Aluminum Electrolytic Capacitors are one of the most commonly used electronic components. They are used primarily in analog circuits for energy storage, frequency shaping, voltage multiplication, and other filtering functions. The UPW2D471MRH is an example of such a capacitor typically used in a variety of applications including LED lighting and power supplies. This article will explore the application field and working principle of the UPW2D471MRH.

Application Field

The UPW2D471MRH is an aluminum electrolytic capacitor with a voltage rating of 50V and a capacitance of 470μF. It is a typically electrolytic capacitor with a radial lead, through-hole mounting, and has an operating temperature range of -40°C to +85°C. This type of capacitor is ideal for a wide range of applications including:

• Power supplies
• LCD/LED displays
• Mobile circuit boards
• Audio/video equipment
• Automotive electronics

The UPW2D471MRH is a reliable and efficient capacitor for these applications, as its low equivalent series resistance (ESR) and high ripple current capacity make it suitable for smoothing power supply noise, reducing DC offset, or increasing peak current.

Working Principle

To understand the working principle of the UPW2D471MRH it is necessary to first understand its construction. The capacitor consists of two metal plates with an electrolyte between them. The metal plates have a positive and negative charge respectively and the electrolyte acts as an insulator between them. When a voltage is applied, current flows through the electrodes and is stored in the capacitor.

How the capacitor works depends on the frequency of the applied voltage. When a DC voltage is applied, the capacitor acts as a load, allowing current to flow. This means it acts as a short circuit and draws a certain amount of current. At very high frequencies, however, the capacitor acts as an open circuit and no current flows. It is this property of capacitors that allows them to be used for filtering, smoothing, and voltage multiplication.

In addition to voltage application, temperature is also an important factor in the performance of the UPW2D471MRH. The working temperature range of the capacitor is limited and must be kept within the specified range in order to ensure reliable operation. Exceeding the specified temperature range may have an adverse effect on the performance and lifetime of the capacitor.

Conclusion

In conclusion, the UPW2D471MRH is an aluminum electrolytic capacitor with specific applications and a working principle that must be considered for correct operation. The capacitor is suitable for a variety of applications such as power supplies, LCD/LED displays, mobile circuit boards, audio/video equipment, and automotive electronics. The capacitor works by allowing current to flow when a DC voltage is applied, although at higher frequencies it acts as an open circuit and no current flows. Temperature is also an important factor in the performance of the capacitor, as the working temperature range must be kept within the specified range for reliable operation.
