Aluminum electrolytic capacitors, often referred to as "electrolytics," are capacitors which use an electrolyte – an ionic conducting liquid – as one of its plates to achieve higher levels of capacitance than what would be possible with conventional, dielectric capacitors. The EKZE101ELL471MM25S, known as a ‘miniature radial aluminum electrolytic capacitor’, is designed for use in a wide range of applications, from signal path filtering in consumer electronics to power supply bypassing in motor drives.

The specific characteristics of aluminum electrolytic capacitors rely on a ‘wet’ technology construction which combines the use of a pure aluminum foil as a cathode working against an electrolyte layer coated with a porous dielectric material, usually an organic manganese dioxide layer with mixed conductive particles, as an anode. This two-layer structure allows for higher maximum capacitance levels and higher voltage ratings as compared to other types of capacitors.

The EKZE101ELL471MM25S is a radial leaded aluminum electrolytic capacitor with a cylindrical aluminum shell and a maximum working voltage of 25 Volts. It has a capacitance of 47µF which provides wide range filtering and has an operating temperature of -40°C to 85°C. The EKZE101ELL471MM25S offers a moderately wide temperature range and is well suited for a variety of applications which require reliable performance.

In terms of its mechanics, the EKZE101ELL471MM25S consists of a closed-end cylindrical anodized aluminum electrolyte can housing the ‘disc’ or ‘can’ style capacitor contained within. An insulated metalized polymer film construction ensures the capacitor’s long-term reliability with low leakage current, low impedance and excellent working temperature stability performance. A sleeve of semi-conductive film on the bottom forms an Arc Barrier (ARC), preventing potential spark-gap arcing and helps minimize gas formation and thermal runaway. The capacitor\'s electricals and mechanicals are further protected by an epoxy resin sleeve coated with a layer of electrical insulation material.

The main working principle of the EKZE101ELL471MM25S is the same for all aluminum electrolytic capacitors. A voltage applied across the structured amount of aluminum plates makes up for the anode and metalized layer of dielectric material becoming the cathode. This creates an electrolytic field between the layers, allowing for an electric current to flow and thus storing electrical energy. The capacitance stored is directly proportional to the surface area of the plates, the distance between them, and the mediums dielectric constant, or their permittivity.

The EKZE101ELL471MM25S is primarily designed for use in audio power amplifiers, fluorescent lighting, uninterruptible power supplies, telecommunications equipment, consumer electronics, industrial controls, and automotive applications due to its high capacitance value and long-lasting performance in demanding environments.

In conclusion, the EKZE101ELL471MM25S is a miniaturized radial aluminum electrolytic capacitor ideal for applications requiring high capacitance density and superior voltage endurance in difficult conditions. With its hermetically sealed cylindrical aluminum housing, the capacitor ensures dependable input output noise filtering and current electrical energy storage in a wide variety of demanding applications.
