Super Capacitor Modules

Supercapacitors, also known as ultracapacitors, are excellent for supplying current peaks due to their low internal resistance. This can significantly increase the service life of a battery. In some applications, the battery can even be replaced.


Powerstor Super Caps for Back-Up & Power Pulse applications from Eaton offer:

  • Extremely high capacities (Farad)
  • Carbon foam technology
  • Factor of 2000 smaller than equivalent electrolytic capacitors
  • Extremely low internal resistance (ESR) for high pulse power
  • Factor 10 higher surge current compared to Li-ion batteries
  • Extremely high discharge cycles, almost infinite compared to batteries
  • Extremely low leakage current - component can hold its charge for weeks
  • Handles surge current load and increases battery life when operated in parallel

This unique technology of aerogel capacitors gives the product ideal characteristics for various applications, such as:

  • Portable devices
  • Charging cells for DC power supplies
  • Battery backup replacement
  • Battery hybrid, parallel operation of battery + SuperCap
  • Bridging power for seconds, minutes, days, etc.

The strength of Maxwell ultracapacitors lies in high performance for power supplies and transportation applications while maintaining great ruggedness and vibration resistance.
