Ultracapacitors provide powerful storage
NessCap has added 3 to 100F models to its exclusive 2.7V ultracapacitor product line.
NessCap has added 3 to 100F models to its exclusive 2.7V ultracapacitor product line. Part of the first ultracapacitor family with a continuous operating voltage rating higher than 2.5V, the new models are available in seven different capacitance ratings designed to meet a variety of primary or backup energy needs for compact electronics. With a capacitance tolerance of -10 to +20% and a surge voltage capability of 2.85V, the new NessCap 2.7V ultracapacitors have the highest capacitance and energy densities in their class along with exceptionally low equivalent series resistance (ESR).
The 100F model has an energy density of 4.5Wh/kg, and an ESR value of only 10mohm at 1kHz, with rated current of more than 21A and maximum current of 58A.
These maintenance-free, efficient, high-capacity energy storage devices enable designers of power systems to increase product life, reduce or eliminate battery use and improve peak power availability.
A unique electrode formation using activated carbon coupled with NessCap's proprietary and patented electrode manufacturing processes enable the component's outstanding performance characteristics.
These characteristics make NessCap's 2.7V ultracapacitors an ideal energy source for a range of compact applications including LED displays, remote control devices, toys, hand-held scanners, small printers, car audio, actuators and relays.
With approximately 10 times the specific power of a similar sized battery coupled with the ability to withstand more than 500,000 discharge cycles without significant performance degradation, ultracapacitors are proving themselves as intermediate power sources and battery performance enhancers.
When used in conjunction with batteries, the ultracapacitors deliver peak power to reduce the required battery size while minimising battery discharge cycles to effectively extend battery life.
By supplying peak load demands, ultracapacitors help batteries last longer because they eliminate the repeated high power demands that are the primary cause of premature battery aging.
With the new compact sizes and ability to withstand 500,000 discharges with no maintenance, NessCap ultracapacitors allow designers to use smaller batteries that will last longer, while keeping overall product size and cost to a minimum.
In many cases the ultracapacitor will never need to be replaced.
Available now with ratings of 3, 5, 10, 25, 50, 90 and 100F, pricing for the new models is based on the quantity ordered starting at US $0.80 for sample quantities of the 3F device.
All the new models feature a convenient cylindrical cell form-factor and boast an operating temperature range of -40 to +60C and a projected operating life of 10 years.
