Aluminum electrolytic capacitors are important components used in a wide variety of electrical and electronic circuits. The LNX2J272MSEJ is an aluminum electrolytic capacitor specifically designed for use in high-performance and high-voltage requirements. Here we descirbe the application fields and working principles of the LNX2J272MSEJ.

Application Field

The LNX2J272MSEJ is a multi-terminal, low-impedance aluminum electrolytic capacitor, which has good temperature characteristics and high reliability. Its maximum operating temperature is 125°C, which makes it suitable for applications that require a higher temperature rating. It is also suitable for a variety of power supply and high-voltage requirements in which it can be used as both a power supply filter capacitor or as a storage capacitor in motor drives and inverter applications. It is ideal for applications that require low-ESR, high-temperature operation, and high-reliability.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the physical properties of aluminum, which is a porous metal. A thin layer of aluminum oxide forms on its surface, which acts as an insulator to create a barrier between the two layers of aluminum and prevents current from passing through it. This layer of aluminum oxide together with the porous surface of the metal allow electrons to flow through the metal, thus creating a capacitor.

The LNX2J272MSEJ is constructed using a special, low-profile aluminum foil and electrolyte which is then sealed with a special heat-resistant, epoxy resin. This combination reduces the thickness of the capacitor and provides enhanced reliability under extreme temperatures and high-voltage application, ensuring high-performance operation even during high-voltage spikes. Inside the capacitor, two metal plates are separated by an electrolyte, with electrolyte-filled cavities between them. As an external voltage is applied, an electrical charge builds up on the metal plates, thus creating an electric field between the plates.

The electric field created between the plates attracts and repels electrons, thus creating a capacitance. This capacitance is then used to store electrical energy and to control the current flowing through the circuit. Thus, the LNX2J272MSEJ aluminum electrolytic capacitor is ideal for applications in high-frequency switching, power supplies, motor drives, inverters, and resonators.
