Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electrical and electronic products because of their high capacitance-to-volume ratio, low cost, and long life. An ELXY250ELL181MJC5S aluminum electrolytic capacitor is a component in the form of a cylindrical can with values of 250V, 15uF, and an operating temperature range of -40°C - +105°C.

Application Field

Because of their high capacitance and small size, ELXY250ELL181MJC5S capacitors are commonly used as part of a power supply filtering system, typically to filter high frequency noise that passes through the power supply, and to reduce transients caused by current spikes. Other common applications are switching power supplies, power line filters, control circuits, audio equipment, and home theatre systems. These capacitors are also used in automotive and industrial systems, such as motor controls, solenoid valves, and robotics.

Working Principle

The ELXY250ELL181MJC5S aluminum electrolytic capacitor works on the principle of an electrolyte, usually a chemical liquid that contains charged ions, and an electrolytic film as the electrical barrier. This capacitor is composed of two metal plates (anodes) separated by an aluminum oxide film (dielectric) with a wet electrolyte. When the capacitor is charged, a chemical reaction takes place and the oxide film becomes a dielectric, blocking the flow of electrons from one plate to the other. This creates the capacitance which allows the capacitor to store charge for later use.

The ELXY250ELL181MJC5S aluminum electrolytic capacitor is constructed of an electrolyte-filled aluminum film, an anode and electrolyte as the dielectric, and a metal can as the electrode. The electrolytes and anode provide an electrical barrier between the two plates, blocking current and creating the capacitance. The can, or housing, serves two purposes; it is first a structural support for the capacitor and the dielectric and secondly, it assists the metal anode in the dissipation of heat and the absorption of the energy within the capacitor.

Because these capacitors use a metal can, they are able to dissipate heat faster than other types of capacitors. The ELXY250ELL181MJC5S aluminum electrolytic capacitor is designed to withstand temperatures up to 105°C and pressures up to 1.5 bars, increasing the life of the capacitor and allowing it to be more resistant to temperature fluctuations and environmental extremes.

The ELXY250ELL181MJC5S aluminum electrolytic capacitor is an important component of most modern electronics equipment, and provides the necessary electrical power storage to keep the device running. It is an invaluable device for improving system performance and extending the life of your equipment.
