Aluminum Electrolytic Capacitors are a type of capacitor that is widely used due to its ability to provide quick and reliable energy storage. The ELXM401VSN181MR30S is a contactless radial leaded aluminum electrolytic capacitor, and is suitable for applications in a variety of fields. In this article, the application field and working principle of the ELXM401VSN181MR30S will be explored.

Application Field

This contactless radial leaded aluminum electrolytic capacitor is suitable for applications in general industrial, consumer and lighting applications, energy storage, and motor drive. It has also been used in audio applications, server applications, automotive and battery systems, and HVAC systems. Other uses include general DC filtering circuits, switching power supplies, UPS, and buffering and signal conditioning applications.

Working Principle

An aluminum electrolytic capacitor is a capacitor that consists of two aluminum plates separated by a dielectric that is an oxide layer. The oxide layer acts as an insulator between the two plates allowing current to flow between them. The oxide layer is formed when aluminum and an electrolyte solution are combined in a process called “electrochemical oxidation”. This oxide layer is what makes aluminum electrolytic capacitors so robust to voltage and temperature fluctuations.

The ELXM401VSN181MR30S is a contactless radial leaded aluminum electrolytic capacitor which means it has radial leads that are crimped to the top of the can and do not require soldering. This allows for quicker assembly time and improved reliability. Additionally, the contactless radial leaded design allows for higher current ratings and longer life.

In terms of construction, the ELXM401VSN181MR30S is a single-ended aluminum electrolytic capacitor. It has two layers of an aluminum onto which a thick aluminum oxide layer is created between the plates. This oxide layer acts as an insulator to protect the capacitor from high temperature and voltage stresses. The most important feature of this capacitor is the low ESR value and ripple current rating which make it suitable for use in applications such as power supplies, inverters, and other power equipment.

In conclusion, the ELXM401VSN181MR30S contactless radial leaded aluminum electrolytic capacitor is a reliable and robust device that is suitable for use in a variety of applications. It offers excellent current and voltage ratings, long life, and a low ESR value.
