Aluminum - Polymer Capacitors

Aluminum-Polymer capacitors are the newest type of capacitors on the market, and they represent a major departure from earlier aluminum electrolytic designs. They are completely free of liquid electrolytes and instead rely on polymersized materials as the dielectric medium. This provides significant advantages in a variety of applications.

The 80SXE47M is an aluminum-polymer capacitor designed for use in high frequency and high power applications. It has a higher capacitance than traditional aluminum electrolytic capacitors, and its wide temperature range makes it an ideal choice for a variety of applications.

Application field

The 80SXE47M aluminum-polymer capacitor is widely used for power factor correction and energy storage, motor drive and control, power conditioning and monitoring, rectification, and DC-to-DC conversion. It is also suitable for applications involving high frequency, hybrid power supplies, and renewable energy systems.

Working principle

The 80SXE47M aluminum-polymer capacitor works by storing and releasing electrical energy in the form of a continuous current flow. This current flow is regulated by the capacitor\'s internal dielectric, which is formed by a layer of plasticized polymers. The dielectric creates an electrostatic field within the aluminum layers, which stores and releases electrical energy.

When current is applied to the capacitor, a positive charge accumulates on one side of the aluminum layer, and a negative charge accumulates on the other side. This creates an electrostatic field which stores energy and increases the overall capacitance. When the current stops flowing, the charge redistributes itself, returning the capacitor to its neutral state.

The 80SXE47M aluminum-polymer capacitor is designed to operate at a wide range of temperatures and frequencies, which makes it ideal for a variety of high-temperature, high-power applications. It can also be used in demanding conditions where conventional aluminum electrolytic capacitors cannot be used.

Aluminum-polymer capacitors are becoming increasingly popular for many applications due to their superior reliability, size, and cost, compared to traditional aluminum electrolytic capacitors. With the increased demand for high-performance capacitors, aluminum-polymer capacitors are sure to become a mainstay of power electronics design in the years to come.
