Aluminum – Polymer Capacitors

Aluminum-polymer capacitors, often referred to as polymeric electrolytic capacitors, are a form of non-polarized electrolytic capacitor in which aluminum is used as the active electrode material. The capacitor usually consists of an etched aluminum foil strip, a dielectric polymer film and a conductive polymer as the other electrode. The capacitance of the capacitor can vary greatly depending on the type of dielectric material used.

The APXC2R5ARA181ME60G, which stands for X2R substrate aluminum polymer capacitor, is a type of aluminum – polymer capacitor with a simplified tri-layer structure. It is made up of a conductive polymer cathode, a solid polymer anode, and a peripheral X2R dielectric layer. This capacitor is available in various capacitance values ranging from 1.0 μF to 1000 μF (10 VDC to 63 VDC).

Application Fields and Working Principle

APXC2R5ARA181ME60G aluminum – polymer capacitors have a wide range of applications in automotive, consumer, industrial, and medical electronics. They are ideal for use in high frequency and high power applications, such as DC/DC converters, switch-mode power supplies, and motor control applications. The capacitors can provide stable, efficient performance in demanding environments, such as high temperature and high humidity.

The capacitors work on the principle of ‘electrostatic charge’, created by a dielectric medium placed between two metal plates. When a voltage is applied to the two metal plates, positive and negative charges starts accumulating on the opposite sides of the dielectric medium, creating an electrostatic field force. This electrostatic field force produces a capacitive effect which causes electrical energy to be stored across the plates. As the capacitance value increases, the amount of electrical energy that can be stored by the capacitor also increases.

When an alternating voltage is supplied to the capacitor, the charges on the capacitor, alternately producing positive and negative potentials and creating an oscillation of electrical current. This alternating current is then used to power electrical appliances and other electronic devices.

Aluminum – polymer capacitors also offer lower equivalent series resistance, as compared to other types of capacitors, resulting in better performance in high frequency applications. The capacitors do not suffer from any temperature related drift in capacitance over its operational temperature range, which makes them ideal for applications in temperature-sensitive systems.

The APXC2R5ARA181ME60G aluminum – polymer capacitor offers superior stability, reliability, and high capacitance values in a compact size. It is well suited for applications that require reliable performance, such as power supplies, automotive, and motor controls. It is also an excellent choice for use in portable devices, LED lighting, and instrumentation applications.
