CDE AT A GLANCE
Ultracapacitors

Cornell Dubilier offers the most advanced ultracapacitor technology available for demanding
applications in renewable energy, electric vehicles and real time clock and battery backup. With
styles ranging from SMT to large cylindrical cells, CDE has the broadest array of ultracapacitors
available in the industry today.

Board Mount Ultracapacitors - Type EDL
Type EDL ultracapacitors offer extremely high capacitance values (Farads) in a variety of packaging options that
will satisfy low profile, surface mount, through hole and high density assembly requirements. SMT, Stacked Coin
and Radial leaded styles have capacitance values ranging from .022 up to 100 Farads and voltage ranges from 2.1
to 5.5 volt.
• Unlimited charging and discharging capability

Long Life
Low ESR
Extend battery life up to 1.6 times
Operating temperatures from -25 to +85 C

Large Cell Ultracapacitors – Type CDLC
Large ultracapacitors handle back-up and pulse power applications such as grid stabilization. They also excel
in transportation 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, thereby 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 High Cycle Life
performance degradation.

Hybrid Ultracapacitors - Type CDHC
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 makes them especially suitable
for use in LED lighting and emergency pulse applications, e.g. operation of electric doors and windows.
