EEF-HE0G181R Capacitors

Aluminum - Polymer Capacitors

Aluminum - Polymer capacitors, also known as aluminum electrolytic capacitors (AECs), are a type of capacitor that uses electrolytically-formed aluminum oxide as its dielectric. AECs are typically used for applications such as high-frequency switching, high voltage/current operations, DC-DC converters, and audio/video applications. The EEF-HE0G181R is a particular type of aluminum electrolytic capacitor with some unique features and advantages, making it particularly suited for switching and converter applications.

EEF-HE0G181R Application Field

EEF-HE0G181R aluminum-polymer capacitors offer a wide range of benefits and features, making them well-suited for a variety of applications, including high-frequency switching, high-voltage/current operations, DC-DC converters, and audio/video applications. This type of capacitor offers increased energy density over traditional electrolytic capacitors, allowing it to support higher voltage/current, while providing improved temperature performance.

Due to their high reliability, wide temperature range, and relatively low ESR (Equivalent Series Resistance), they are also well suited for automotive applications, as they offer a wide range of temperature and environmental performance. They are also well suited for use in audio applications, as they can provide improved audio devices with low ESR and increased energy density.

EEF-HE0G181R Working Principle

The Working Principle of the EEF-HE0G181R aluminum-polymer capacitor is based on the application of electrolyte to the aluminum oxide film on the electrode plates. This electrode plate is made of aluminum, and it is then treated with an acid electrolyte, which then forms an oxide film on the aluminum. This oxide film acts as a dielectric, allowing current to flow between the plates, but preventing direct contact between them. The electrolyte also allows the ions from the acid to pass through the oxide film and form a capacitive charge on the plates.

The electrolyte applied to the oxide film also contains supporting electrolytes and ions that help to stabilize the oxide film and improve its electronic properties. This results in an increased energy density and an improved cooling effect, making the EEF-HE0G181R a more efficient and reliable capacitor.
