Aluminum - Polymer Capacitors

Aluminum - polymer capacitors are electronic components that are used in a variety of electronics applications. They are typically used in switching power supplies, high-frequency electronics, and medical and telecom applications. The RNU1H390MDN1 is an aluminum - polymer capacitor designed to provide greater energy storage than aluminum electrolytic or tantalum electrolytic capacitors. The capacitor offers a high volumetric efficiency of 15.5 (FV/cm³) and an operational temperature range of - 40°C to 85°C. It also has a longer life-time than other aluminum electrolytic capacitors.

Application Field

The RNU1H390MDN1 is suitable for applications that require higher density, higher voltage and higher efficiency, such as power supplies, computers, electronic test equipment and communication equipment. The capacitor offers a high volumetric efficiency of 15.5 FV/cm³ and an operational temperature range of -40°C to 85°C. It can also be used in hybrid systems as energy storage and power conversion components.

Working Principle

Aluminum-polymer capacitors are constructed of an anode and a cathode separated by an electrolyte material. This material is usually a blend of organic, inorganic and polymer components which gives the capacitor its unique properties. The organic component comprises a conductive polymer layer and can be tailored to suit the application. The inorganic component consists of an aluminum oxide film and the polymer component is the electrolyte material. When voltage is applied, the electrolyte layer separates the two electrodes and stores the electric charge. The electrolyte provides the dielectric that controls the capacitance and the effective capacitance range of the capacitor. The electrolyte layer is also important for thermal and environmental stability, and contributes to the long-term reliability and lifetime of the capacitor.The RNU1H390MDN1 offers superior performance over traditional aluminum electrolytic or tantalum electrolytic capacitors. Due to the high volumetric efficiency and low Equivalent Series Resistance (ESR) of the aluminum-polymer capacitors, they are able to provide higher capacitance and higher voltage than traditional capacitors. Overall, the RNU1H390MDN1 aluminum-polymer capacitors provide higher capacitance, higher voltage, better energy storage, and longer life-time compared to traditional aluminum electrolytic or tantalum electrolytic capacitors. As such, they are ideal for a wide range of applications from power supplies, computers and electronic test equipment, to communication equipment, hybrid systems, and more.
