New Snap-in and Hybrid Lithium-Ion CarbonCap Cylindrical Ultracapacitors

These hybrid capacitors store more than twice the energy of typical ultracapacitors and have high cycle life capability compared to batteries.

New Bedford, MA (April 2012) — Cornell Dubilier announces the release of Type CDLC, CarbonCap Double Layer Capacitors and Type CDHC hybrid ultracapacitors. Cornell Dubilier's lineup of large cell cylindrical ultracapacitors spans 1200 to 3000 farads; snap-in style ultracapacitors from 100 to 600 farads and higher energy hybrid capacitors from 220 to 1000 farads.

Type CDHC Hybrid Capacitors are half ultracapacitor and half lithium-ion battery. These hybrid capacitors store more than twice the energy of typical ultracapacitors and have high cycle life capability compared to batteries. Hybrid capacitors have more power than lithium-ion batteries, but less energy storage. By comparison, ultracapacitors have a cycle life capability of a million cycles or more, batteries have a cycle life of around 1000 cycles and hybrid capacitors, more than 20,000 cycles. While the ultracapacitors have a usual working voltage range of 1.3 to 2.7 V, hybrid capacitors operate from 1.0 to 2.3 V. The higher energy of hybrid capacitors make them especially sutiable for use in LED lighting and emergency pulse applications, e.g. operation of electric doors and windows.

Type CDLC CarbonCap Ultracapacitor Cells are available with axial, M12 threaded mounting studs on both ends as well as additional mounting options. The new snap-in units are available in 2- and 4-pin versions and are well suited for wind turbine blade pitch control.

The large ultracapacitors handle back-up and pulse power applications, such as grid stabilization. They also excel in transporation applications like automotive subsystems, rail system power and utility vehicles. They provide extended power allowing critical information and functions to remain available during dips, sags and outages in the main power source. These cells can relieve batteries of burst power functions, therby reducing costs and maximizing space and energy efficiency. Units with axial cylindrical design enables low ESR and high peak currents with an electrostatic storage capability that can cycle a million charges and discharges without performance degradation.

Type CDLC can work in parallel with batteries for applications that require both a constant power discharge for continual function and a pulse power for peak loads. The Type CDLC delivers the peak power, thus reducing the peak current from the battery and extending battery life and reducing battery size and cost.

Both series are available now with prices starting at $10.00 each.
