Suwon, Kyonggi-do, Korea NessCap Co. Ltd. has expanded its 2.7-volt ultracapacitor product offering with the addition of 3 farad (F) and 100F models. These components can be used as an energy source for a variety of applications including LED displays, remote control devices, toys, hand-held scanners, small printers, actuators and relays.
The company said these maintenance-free, high capacity energy storage devices enable designers of power systems to increase product life, reduce or eliminate battery use and improve peak power availability.
Featuring a cylindrical cell form-factor, the new models are available in seven different capacitance ratings 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 offer the highest capacitance and energy densities in their class as well as low equivalent series resistance (ESR), according to the company.
The standard operating temperature range is -40°C to 60°C. The projected operating life is 10 years
The 100F model has an energy density of 4.5 watt-hours per kilogram, and an ESR value of 10 milliohms at 1kHz, with a rated current of more than 21 amps and maximum current of 58 amps.
With approximately ten 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, the ultracapacitors can be used as intermediate power source and to enhance battery performance.
When used in conjunction with batteries, the ultracapacitors deliver peak power to reduce the required battery size while minimizing battery discharge cycles. By supplying peak load demands, ultracapacitors can extend a battery's life by eliminating the repeated high power demands that are the primary cause of premature battery aging.
Available with ratings of 3F, 5F, 10F, 25F, 50F, 90F and 100F, pricing for the new 3F device starts at $0.8 for sample quantities.
