High Performance Electrical Double-Layer Capacitors
To meet consumer demand for mobile devices with greater efficiency
and functionality, Murata began focusing its R&D efforts on Electrical
Double-Layer Capacitors (EDLC) in 2008, at which time we made a
strategic decision to license leading-edge supercapacitor technology
from CAP-XX Limited (CAP-XX), an Australia-based firm. Working
from this collaborative basis, Murata has enhanced the design and
manufacture of these high power (low ESR) EDLCs in a compact, slim
package, and we continue our research efforts to develop even better
and higher performing products.
Electrical Double-Layer Capacitors (EDLCs), often referred to as
supercapacitors, are energy storage devices with high power density
characteristics that are up to 1,000 times greater than what is typically
found in conventional capacitor technology. Murata’s Electrical Dou
ble Layer Capacitor combines these advanced characteristics in a small
and slim module. Optimization of electrochemical systems, including
the electrode structure, enables flexible charging and discharging
from high to low output over a range of temperatures. By supporting
momentary peak load, the components also level battery
load and can drive high-output functions that are difficult for
batteries alone.
Features
High power output and high energy: 5.5V
Compact and slim: 21.0mm x 14.0mm x 2.5mm
Wide operation temperature range from -30°C to +70°C
Low ESR: 40mΩ – 60mΩ
– Stable ESR at lower temperatures
ESR change @ -30°C < twice the nominal ESR
Low leakage current
– Typical leakage less than 10μA@96hrs
Long cycle life - exceeding 100k cycles
Benefits
Leveling the high peak load up to hundreds of milli-seconds
– Extend battery run time and cycle life by stable combination with EDLC
– Enable the use of lower power battery or reduction of the number of
series connections
– Enable the use of high peak load applications without high power
battery
