Aluminum - Polymer Capacitors

Aluminum-polymer capacitors (also known as Aluminum-Polymer-Multi-Layer Capacitors or APML) are the latest generation of aluminum electrolytic capacitors, featuring solid, foldable electrolyte designs, along with low ‘ESR’ (Equivalent Series Resistance) and low leakage current. These capacitors offer many advantages over traditional aluminum electrolytic capacitors, such as a wide temperature range, higher current carrying capacity, higher ripple current ratings, and high surge current ratings.

The aluminum - polymer capacitors ESRE391M0ER-F are specifically designed for the military and defense applications. These capacitors are built using a hybrid dielectric blend of electrolytes consisting of three different polymorphs of inorganic electrolyte, with superior electrical and environmental characteristics compared to traditional electrolytic capacitors.

The ESRE391M0ER-F capacitors are designed to provide higher peak currents and power handling while maintaining a very low ESR. The capacitors provide extremely reliable operation in harsh environments, including high-frequency and high-temperature applications. They also feature superior shock and vibration resistance, and excel in other applications, such as power supplies and motor drives.

The working principle of the aluminum-polymer capacitor ESRE391M0ER-F is the same as traditional aluminum electrolytic capacitors. It uses an electrolytic solution as the dielectric medium, which changes the electric field between the two plates and stores the charge. There are two electrodes with an electrolyte solution spread in between them. An electric field is created by applying an external voltage to the insulator. This field creates an electric flux and stored energy between the two electrodes. As the electrolyte solution responds to changes in the external electric field, more energy is stored, which results in capacitor charging.

The aluminum-polymer capacitors ESRE391M0ER-F can be used in a wide range of applications such as AC filters, DC holdup capacitors, energy storage capacitors, high-voltage pulse capacitors, noise filtering and EM interference suppression. The capacitors are ideal for applications requiring superior performance and high levels of reliability.

The aluminum-polymer capacitor ESRE391M0ER-F is designed to provide a robust and reliable solution for military and defense applications. The capacitors have excellent electrical characteristics, including high peak current and energy handling capabilities, low ESR values, and excellent reliability. Their superior shock and vibration resistance make them ideal for use in harsh environments.
