ELECTRIC DOUBLE
LAYER CAPACITORS
TECHNICAL NOTE
1-4 Construction of DYNACAP
The basic cell construction of the DB, DBN, DX,
DXJ, DH, DK, DBJ, DC, DCK, DS, and DSK series is
similar to that of coin-type batteries as shown in Fig.2.
DYNACAP contains a single cell or two to three cells
stacked in series.
Since these series have a large electrode-to-electrode
distance and a small electrode area exhibiting a large
internal resistance, they are suitable for the memory
backup application that involves microcurrent
discharge.
These series have a small electrode-to-electrode
distance, allowing a large electrode area because of
the winding structure. This decreases the internal resis-
tance, which is primary suitable for applications requir-
ing high-power such as motor drive and LED Iighting
that need high currents.
2 Description of Life Expectancy
Generally, the life of Electric Double Layer Capacitors is
largely affected by the ambient temperature.
The expected life is approximated by the equation as
shown below:
The cylindrical cell construction as seen in the DZ and
DZN series has the construction similar to that of

Note that the above equation does not cover charge
and discharge. In the case of charge and discharge,
heat generation occurs inside a capacitor; the
temperature rise by this heat generation must also be
considered.
