ELECTRIC DOUBLE LAYER CAPACITORS
Cautions for Using Electric Double Layer Capacitor (DYNACAP, POWERCAP)
■ Usage
1. Electric double layer capacitors (EDLC) use a
conductive organic electrolyte.
The use at excessive mounting temperature or
exceeding the upper category temperature can
cause the electrolyte to leak. Especially, coin and
multilayer coin types for the memory backup (DB,
DBN, DBJ, DX, DXJ, DXL, DH, DK, DC, DCK, DS,
and DSK series) excluding the DZ, DZH, DZN and
DP series use a low elastic plastic as the sealant in
the cell construction like coin batteries; therefore,
avoid using such capacitors in the vicnity of auto-
motive equipment with steep temperature change,
and heating element such as motor, relay, trans-
former, power IC, etc. because of the risk of leak-
age of electrolyte.
2. Since EDLC is polarized, do not apply a
reversed voltage.
EDLC is polarized. If a reversed voltage is applied
for a long time, the leakage current will increase
abruptly, which may cause a decrease in the
capacity, an increase in the internal resistance,
and causing leakage or damage to the product in
some cases.
3. Do not apply any voltage higher than the
operating maximum voltage (this means the surge
voltage in the case of short-time charge).
If an overvoltage is applied to the product, the
leakage current will increase abruptly and the
product will become overheated, which may cause
a decrease in the capacity, an increase in the
internal resistance, and causing leakage or damage
to the product in some cases.
4. Do not use smoothing a power supply (for
absorbing its ripple).
Since the internal resistance of EDLC is high, the
product will be overheated if it is used for smoothing
a power supply (for absorbing its ripple), which may
cause a decrease in the capacity. an increase in
the internal resistance, and causing leakage or
damage to the product in some cases.
5. Do not use in a circuit where quick charge and
discharge are repeated very often.
In a circuit where quick charge and discharge are
repeated very often, the product will become
overheated, which may cause a decrease in the
capacity, an increase in the internal resistance, and
causing leakage or damage to the product in some
cases.
Reduce the charge and discharge currents while
selecting a product with low internal resistance, and
make sure that the product surface temperature
does not rise.
6. EDLC life depends heavily on the ambient
temperature.
① The lifetime of EDLC is seriously affected by
change in ambient temperature. lf the temperature
is lowered by 10°C, the lifetime will be approxi-
mately doubled. Therefore, the product should be
used at a temperature lower than the guaranteed
maximum value for maximum life.
② If the capacitor is used at a temperature
exceeding its maximum guaranteed temperature,
NOTE
Design, Speci?cations are subject to change without notice.
Ask factory for technical speci?cations before purchase and/or use.
not only is its life shortened, but increased vapor
pressure of electrolyte or electrochemical reactions
may increase the internal pressure, and causing
leakage or damage to the product in some cases.
7. Note that a voltage drop in EDLC occurs during
backup.
ln a case where discharge current is Iarge, or a
large current flows instantaneously. an electric
double layer capacitor may not operate at the start
of discharge because of a large voltage drop (IR
drop) caused by the product with the DC internal
resistance.
Please consult us for a large discharge current (in
the case of other series except DZ, DZH, DZN and
DP series: when larger than l [mA] ＝ 1 × C[F]) as
the internal resistance varies by each series. (Re-
commendation discharge current: less than 1
mA/F at 20°C)
8. Do not use the product in an ambient atmo-
sphere containing waterdrops (condensation) or
toxic gases.
Although EDLC is sealed, water droplets or toxic
gases may do degradation characteristics, a
leakage and corrode the lead wires and the case,
which may cause a breaking of the wires.
Avoid abrupt temperature changes, which may cause
water droplets, resulting in product deterioration and
electrolyte leakage.
9. Contact us before connecting the products in
series.
A series connection will cause an imbalance in the
voltage, charged to the capacitors and an
overvoltage may be charged to one or more them.
This may cause a decrease in the capacity, an
increase in the internal resistance and causing
leakage or damage to the product in some cases.
When using series connection for several
capacitors, please derate the applied voltage from
the operating maximum voltage or use balancing
circuits (bleeder resistor, etc.) to compensate for the
imbalance in the applied voltage for each capacitor.
Moreover, please ensure the arrangement does not
cause temperature fluctuation between capacitors.
10. About vibration.
A terminal blank, a terminal bend, and a crease
may occur by adding too much vibration to a
capacitor.
Moreover, depending on the case, an EDLC may
do degradation of the characteristic, breakage, and
a leakage.
When you become too much vibration, please
contact us.
11. When used on a double sided printed circuit
board, do not overlap the wiring patterns on the
mounted part.
A short circuit may be created by certain wiring
conditions. Should the electrolyte leaks, the circuit
pattern may cause a short circuit, resulting in
tracking or migration.
12. Do not keep in high temperature and high
humidity atmospheres.
① Avoid high temperature or high humidity or direct
rays when storing capacitors.
