Aluminum - Polymer Capacitors

Aluminum-polymer capacitors are widely used in many applications because of their excellent performance characteristics, low cost, and ease of manufacture. The RNU1D681MDN1 aluminum-polymer capacitor is a robust, high-capacitance, ultra-low ESR capacitor that can be deployed in a variety of applications and environments.

What are Aluminum-Polymer Capacitors?

Aluminum-polymer capacitors are multi-layer capacitors with an anode identified by an aluminum sheet, which is embedded in a solid or gel polymerized electrolytic capacitor. The encapsulated construction makes aluminum-polymer capacitors highly durable and able to withstand a range of temperatures and operating conditions. These capacitors are particularly renowned for their low equivalent series resistance (ESR). Due to their low ESR, aluminum-polymer capacitors are able to offer a wider range of capacitance and working voltages, making them the perfect solution for many applications requiring the lowest ESR possible.

RNU1D681MDN1 Working Principle

The RNU1D681MDN1 aluminum-polymer capacitor utilizes an anode made of aluminum which is embedded in a solid or gel polymerized electrolytic capacitor. The anode is then connected to a second electrode via a conductive path known as the cathode. When the capacitor is connected to a power source, a current passes from the anode to the cathode, allowing the capacitor to store an electrical charge. The stored charge is then released when the capacitor is connected to a different power source. This capacitor features a self-healing ESR of 0.11Ω, meaning the leakage current is reduced significantly. Additionally, the snap-in terminals of the RNU1D681MDN1 ensures a secure connection and good heat dissipation due to the improved thermal contact. This makes the capacitor suitable for high-stress applications requiring a reliable connection in harsh conditions.
