Aluminum - Polymer Capacitors are a type of electrolytic capacitor which consists of a metalized-plastic foil as a positive electrode, an anode with a porous layer. The negative electrode is a metal foil made of aluminum, steel or brass. The material between these two electrodes is a polymer dielectric. The RNS1D680MDN1PX is a aluminum - polymer capacitor that offers excellent electrical performance with its high insulation resistance and low ESR. It is suitable for use in a wide range of high-reliability and capacitor-intensive applications.

The RNS1D680MDN1PX is a surface-mount multi-layer aluminum - polymer capacitor which offers an ideal combination of high capacitance density, low ESR, and high insulation resistance. It is a low-profile, low-ESR capacitor with the ability to deliver an energy density up to 150% above current level aluminum electrolytic capacitors. It can be used in a variety of high-frequency, high-reliability, capacitor-intensive applications, such as media players, gaming consoles, telecommunications, automotive audio systems, and HVAC applications.

The working principle of the RNS1D680MDN1PX is based on a polymer dielectric material. This material is a combination of a metalized-plastic foil, an anode and a porous layer. The metalized-plastic foil acts as the positive electrode and the anode is made from a metal foil consisting of aluminum, steel or brass. This anode separates and confines the electrostatic charge generated by the surrounding medium. The porous layer is used to increase the capacitance performance of the capacitor. When a voltage is applied to the capacitor, it starts to generate electrostatic charges. This electrostatic charge is stored in the capacitor’s electrodes and the internal polarization of the dielectric will effectively reduce the resulting electric field.

The RNS1D680MDN1PX is designed to provide excellent electrical performance, with high insulation resistance and low ESR. It has a dielectric strength of 3kV, a capacitance range from 0.1µF to 1000µF and an operating temperature range of -25°C to +125°C. The capacitor also features a wide temperature coefficient of capacitance, with typical values ranging from –20ppm/K to + 80ppm/K. This makes the RNS1D680MDN1PX suitable for use in high-temperature applications, as well as high-reliability capacitor-intensive applications.

The RNS1D680MDN1PX offers a number of advantages over traditional aluminum - electrolytic capacitors. It exhibits high capacitance stability over a wide temperature range and has a lower ESR than standard aluminum electrolytic capacitors. Additionally, higher capacitance density and improved electrical performance are achieved due to the use of a high-polarity dielectric material. Thanks to these advantages, the RNS1D680MDN1PX is a highly reliable, long life aluminum-polymer capacitor that is suitable for use in a wide variety of high-reliability, capacitor-intensive, high-frequency applications.
