Eaton hybrid supercapacitors are high reliability, high power, ultra-high capacitance energy storage devices utilizing proprietary materials and processes. This combination of advanced technologies allows Eaton to offer a wide variety of capacitor solutions tailored to applications for backup power, pulse power and hybrid power systems. 
They can be applied as the sole energy storage or in combination with batteries to optimize cost, lifetime and run time. System requirements can range from a few microwatts to hundreds of watts.
All products feature low ESR for high power density with environmentally friendly materials for a green power solution. Eaton supercapacitors are maintenance-free with design lifetimes up to 20 years* and operating temperatures down to -25 °C (HSL) and up to +85 °C (HS)
