Aluminum - Polymer Capacitors

The RNU1E680MDN1PX aluminum-polymer capacitor is a type of high voltage aluminum electrolytic capacitor most commonly used in applications involving high power and long life. Developed in 1965, the aluminum-polymer capacitor has quickly become the standard for high-power and/or long-life applications such as motor drives, DC-DC conversion, and AC motor controllers. The RNU1E680MDN1PX aluminum-polymer capacitor offers many benefits over conventional aluminum electrolytic capacitors including increased electrical stability, increased reliability, and a self-healing feature which makes them immune to damage from overvoltage or current spikes.

Application Field

The RNU1E680MDN1PX aluminum-polymer capacitor is mostly used in high-power, long-life applications such as motor drives and DC-DC conversion. The most common applications for the RNU1E680MDN1PX aluminum-polymer capacitor include:

  • AC motor controllers
  • High-voltage and current sensors
  • Power converters
  • Vacuum cleaner motor drives
  • Switch mode power supplies
  • Automotive starters
  • Air conditioning controller motor drives
  • Laptop power adapters
  • Meters and regulators

Due to its self-healing properties, the RNU1E680MDN1PX aluminum-polymer capacitor is also used in high-voltage surge protection circuits. Furthermore, the RNU1E680MDN1PX aluminum-polymer capacitor is used in medical equipment, industrial control systems and home appliances.

Working Principle

The working principle of the RNU1E680MDN1PX aluminum-polymer capacitor is based on the use of an electrolytic organic substance, such as propylene carbonate (PC). Unlike conventional aluminum electrolytic capacitors, aluminum-polymer capacitors do not require an anode-cathode arrangement. Instead, the electrodes of the RNU1E680MDN1PX aluminum-polymer capacitor are separated by a thin layer of PC and their plasticized bodies are hermetically sealed with plastic end pieces. The PC acts as a dielectric and separates the two electrodes, allowing for a much higher capacitance than conventional electrolytic capacitors.

The self-healing properties of the RNU1E680MDN1PX aluminum-polymer capacitor are also key to its success. In the event of an overvoltage or current surge, the PC will dissipate the heat and limit the current flow, thus protecting the capacitor itself from damage. This self-healing behavior also prevents the capacitor from failing in the event of a sudden power surge. Furthermore, the RNU1E680MDN1PX aluminum-polymer capacitor is highly reliable and offers a very long life expectancy.

In short, the RNU1E680MDN1PX aluminum-polymer capacitor is a high-power, long-lifespan type of capacitor which is becoming increasingly popular in today\'s world. It offers many benefits over conventional aluminum electrolytic capacitors, including increased electrical stability, increased reliability, and a self-healing feature which makes them immune to damage from overvoltage or current surges.
