Aluminum electrolytic capacitors are used in a variety of applications and are seen in a wide range of electronic circuits. The ELXV800ELL471MM25S is an aluminum electrolytic capacitor which is specifically designed for applications which require large current and short circuit handling capability. In this article we will discuss the application field of the ELXV800ELL471MM25S and its working principle.

The ELXV800ELL471MM25S is a radial leaded aluminum electrolytic capacitor. It has a capacitance of 470uF and a rated voltage of 35 Volts. Its maximum ripple current is 130mA and its operating temperature range is -55°C to +125°C. Due to its large capacitance and high voltage rating, it is commonly used in power supply applications such as uninterruptible power supplies and DC-DC converters. Additionally, it is used as an energy storage device in audio amplifiers, switch controllers, and motor-only circuits.

The working principle of an aluminum electrolytic capacitor is based on the so-called electrode-electrolyte principle. This principle is based on the concept that when two metallic surfaces are placed in an electrolyte, a layer of aluminum oxide forms on the surfaces and consitutes an electrolytic barrier. The thickness of the oxide layer determines the capacitance of the aluminum electrolytic capacitor. When a voltage is applied, a current is drawn through the capacitor and charges it up.

When the applied voltage reaches the rated voltage of the capacitor, the voltage across the capacitor starts to drop. This is because the oxide layer at the electrodes is charged and starts to thin. This effect is known as \'dielectric absorption\'. The greater the voltage applied, the more the oxide layer will thin and less current will pass through the capacitor. At this point the ELXV800ELL471MM25S is said to have reached its designed capacitance.

The ELXV800ELL471MM25S has an extraordinary large ripple current capabilityand offers a low ESR (Equivalent Series Resistance). Beyond its already high operating temperature range of -55°C to +125°C, it offers a useful life of 3,000 hrs to 5,000 hrs at 105°C and 10,00 hrs to 15,000 hrs at 85°C. This makes it great for use in high temperature and long life applications.

In conclusion, the ELXV800ELL471MM25S aluminum electrolytic capacitor has a wide range of uses and is a great choice for applications which require large current and short circuit capabilities. Its high voltage rating, low ESR, and wide operating temperature range give it the capability to withstand high temperatures and long-term applications.
