High Efficiency Low ESR Ultracapacitors and Modules
What are Ultracapacitors?
Ultracapacitors, or supercapacitors as they are also known, are an energy storage technology that offers high power density, almost instant recharging and very long lifetimes. Because they store energy in an electric field, rather than in a chemical reaction, they can survive hundreds of thousands more charge and discharge cycles than a battery.
Features and Benefits
Very long lifetimes (up to 1,000,000 duty cycles or 10 year DC life)
Rapid charge and discharge
High efficiency low ESRmax (0.25mΩ for 3000F)
No maintenance requirements
No harmful chemicals or toxic metals
Wide range operating temperatures (from -40 °C to 65 °C)
Typical Applications
Automotive subsystems
Burst/Boost power delivery for cold starting diesel or gasoline engines
Wind turbine pitch control
Hybrid vehicles
Railroad braking
Industrial motor braking
Energy storage recovery
UPS & telecom system power stabilization

The Advantage of Low ESR (Equivalent Series Resistance) Ultra and Super Capacitors
ESR, which involves resistances of cell components, for example, electrolyte resistance and contact resistance between current collectors and electrodes affects the power delivery of a cell. High ESRs restrict the rate at which supercapacitors can be charged and discharged, leading to power reduction and energy dissipation.

Notes for table:
- -x part number suffix (-T) threaded version or (-P) weldable post version
- ΔT = IRMS2 x ESR x Rca
- Power Density (W/kg) = 0.12V 2 / (ESRDC x mass)
- Maximum Energy (Wh) = ½ CV2/3600
- Energy Density (Wh/kg) = ((½ CV2) / 3600) / mass
