Aluminum Electrolytic Capacitors: EFL-250ELL560MF07D

Aluminum electrolytic capacitors are a type of capacitor that uses an aluminum oxide layer on top of the anode with a wet electrolyte as the dielectric. These capacitors are able to store a large amount of charge and are ideal for applications such as power supplies, noise reduction, and filtering. The EFL-250ELL560MF07D is a aluminum electrolytic capacitor from Cornell Dubilier Electronics (CDE) that is designed for use in a wide range of applications.

Application Field

The EFL-250ELL560MF07D is designed for use in applications that require high capacitance, low ESR (equivalent series resistance), and high ripple current. These include power supplies, motor control, and inverter circuits. It is also suitable for high voltage and high frequency applications such as plasma displays, amplifiers, and UPS systems.

Working Principle

The EFL-250ELL560MF07D utilizes an anode consisting of pure aluminum foil in combination with an electrolyte and an organic plasticized film. This creates a Dielectric-Electrolyte-Metal capacitive system. The aluminum foil is rolled and formed into a cylinder. The electrolyte, which is a conductive liquid, is added to the cylinder, along with a plasticized film to create an impermeable barrier. This assembly is then bonded to the anode and sealed with a metal can. The anode and electrolyte affect each other, forming an electric field between them. This field is what allows the capacitor to store electrical energy.

The capacitance of the capacitor is determined by the area of the anode, the type of electrolytic material used, and the dielectric. The ESR is determined by the thickness of the anode and the type of electrolyte. The ripple current of the capacitor is affected by the capacity and ESR.

The EFL-250ELL560MF07D has a capacitance of 560 µF, an ESR of 0.018 Ω, and a ripple current of 7.2 A. It has a rated voltage of 250 VDC, a temperature range of -25°C to +85°C and a life expectancy of 1,000 hours at +85°C. It also has a high insulation resistance and an ESL of 0.13 μH.

The EFL-250ELL560MF07D is an ideal capacitor for applications that require high capacity, low ESR, and high ripple current. Its temperature range and life expectancy make it suitable for a wide range of applications, including power supplies, motor control, and inverter circuits.
