Aluminum Electrolytic Capacitors are often available in two forms, including domestic types that use the ESMR421VSN471MR40S model and imported conversions with ESI-LTL series. Both have the same basic construction but differ in their maximum ratings, tolerance and size.

The ESMR421VSN471MR40S model is one of the most slim and compact Aluminum Electrolytic Capacitors. It offers a wide temperature range of -55°C to 125°C and a total capacitance range of 1000 nF to 4700 μF. The ESMR421VSN471MR40S is a recommended capacitor for low voltage applications, especially in fields such as mobile phones, PCs, televisions and displays. It also has a respectable shelf life of up to 2000 hours.

The Aluminum electrolytic capacitors of ESMR421VSN471MR40S use the metallized anode design in order to save space. The dielectric used is a proprietary polymer designed for excellent reliability and performance. The capacitor is composed of the following components: a polarized aluminum can, an anode and a cathode, an insulating end seal, and a dielectric layer between the anode and cathode.

The working principle of Aluminum Electrolytic Capacitors is based on the Faraday law of electrolysis. When a voltage is applied between the two electrodes, ions are generated in the electron-conducting electrolyte in the anode and the cathode, with the negative ions moving to the anode and the positive ions moving to the cathode. This movement of the ions generates a double-layer electric field on the surface of the electrolyte, and this forms an electric current that is stored in the capacitor.

The main application field of Aluminum Electrolytic Capacitors is in power supply systems. Due to their ability to provide a large amount of energy storage, they are ideal for pulse-charging power supplies, such as those used in solar power systems. They are also used in AC/DC converters, voltage regulators, switched-mode power supplies, and power amplifiers.

In addition to power supply systems, Aluminum Electrolytic Capacitors are also used in industrial, automotive, and audio-visual applications. They are commonly used in applications such as motor starters, inverters, switchgear, LED lighting, and audio components. They are also suitable for high-frequency AC circuits and large ripple current.

Aluminum Electrolytic Capacitors are capable of storing large amounts of electrical energy, making them a very useful component in a variety of applications. The ESMR421VSN471MR40S model is ideal for low voltage applications such as mobile phones, PCs, televisions and displays, and offers a wide temperature range of -55°C to 125°C and a total capacitance range of 1000 nF to 4700 μF. Its working principle is based on the Faraday law of electrolysis.
