EEE-1EA471UAP Capacitors

Introduction

Aluminum electrolytic capacitors are widely used in many electronic products, such as inverters, NC machineries, medical equipments, telecommunication equipments, and digital cameras. The EEE-1EA471UAP is one of the most common aluminum electrolytic capacitor products. Its dimensions are 24 x 20 x 5mm and it has a rated voltage of 25 Vdc. Its maximum ripple current is 25 A and its capacitance is 47 μF.

Nominal Voltage Withstand

The nominal voltage of the EEE-1EA471UAP is 25 Vdc, and its voltage withstand is 1.5 times the nominal voltage or 37.5Vdc. This allows the capacitor to withstand sudden changes in voltage, protecting the capacitor and other components of the circuit. The rated voltage and the maximum ripple current of the EEE-1EA471UAP also determine its voltage withstand.

Temperature Dependency

The EEE-1EA471UAP is temperature dependent, and its capacitance changes as temperature increases or decreases. The temperature coefficient of its capacitance can be as high as -15%/K at temperatures higher than 85 ℃. It is also important to note that the endurance of the EEE-1EA471UAP depends on the temperature at which it is used. The maximum temperature limit is 125 ℃, however, if the temperature exceeds this value, the capacitance can decrease by as much as 30%. Therefore, it is important to ensure that the EEE-1EA471UAP is used in temperature limits as stated in the product data sheet.

Application Field

The EEE-1EA471UAP is widely used in applications where voltage stability and load stability are important, such as in the motor and inverter controls, uninterruptible power supply, computer systems, telecommunication equipments and high-end audio. Although the EEE-1EA471UAP is designed to support a rated voltage of 25 volts, it can handle short-term load spikes up to 37.5Vdc and withstand a wide range of temperature environments.

Working Principle

The working principle of the EEE-1EA471UAP is based on the ability of an electric field to polarize an element. When an electric field is applied to the capacitor, an electric current passes through the aluminum dielectric material and the electrolyte materials, separating them into two layers with a positive charge and a negative charge. This results in an electric field, which causes ions to move across the layers and creates a voltage between them. The resulting charge stored in the capacitor is proportional to the voltage applied to it, and this is the capacitance of the capacitor.

Conclusion

The EEE-1EA471UAP is an aluminum electrolytic capacitor designed for use in applications requiring voltage stability and load stability. It is capable of withstanding a range of temperatures and can handle short-term load spikes up to 37.5Vdc. The working principle of the EEE-1EA471UAP is based on the ability of an electric field to polarize an element and create an electric field, causing ions to move and create a charge stored in the capacitor. The EEE-1EA471UAP can be used for various applications such as motor and inverter control, uninterruptible power supply, and telecommunication equipment.
