Electric Double Layer Capacitors (Gold Capacitor)
Application Guidelines (Gold Capacitor)
1. Circuit design
1.1 Product Life
The life of an electric double layer capacitor is limited. Its capacitance will decrease and its internal
resistance will increase over time.
The life of a capacitor greatly depends on the ambient temperature, humidity, applied voltage and
discharging currents. Capacitor life can be extended when these parameters are set well below the ratings.
The guaranteed durability of electric double-layer capacitors is between 1000 hours at 70 °C and 6000
hours at 85 °C. depending on product series. Generally, it is 1000 hours at 70 °C. The life of the capacitor
is guaranteed to be 16000 hours at a normal temperature (30 °C) by applying the acceleration double for
every 10 °C. Please choose the product that is suitable for the reliability that you need.
If your application incorporates this capacitor over a long period of time, then check it periodically and
replace it when necessary.
1.2 Polarity and voltage
Capacitors have polarities.
Do not apply a reverse or AC voltage. If a reversed voltage is applied to a capacitor for a long period of
time, then its life will be reduced and critical failures such as electrolyte leakage might occur.
Do not apply an over-voltage (a voltage exceeding the rated voltage).
If voltage exceeding the rating is applied to the capacitor for a long time, then its life will be reduced and critical
failures such as electrolyte leakage or physical damage due to gas generated by electrochemical reaction or
explosion might occur.
1.3 Circuits though which ripple currents pass
When using a capacitor in a circuit through which ripple currents pass, please note following matters.
(1) The internal resistance of electric double-layer capacitors is higher than that of electrolytic capacitors.
Electric double-layer capacitors may generate heat due to ripple currents.
(2) Please do not exceed the maximum operating voltage when the voltage changes from ripple.
(3) Because internal resistance is high, the gold capacitor is not basically suitable for the absorption of ripple
current.
1.4 Ambient temperature and product life
Capacitor life is affected by usage temperatures. Generally speaking, capacitor life is approximately doubled
when the temperature is decreased by 10 °C. Therefore, lower the usage temperature as much as possible.
Using capacitors beyond the guaranteed range might cause rapid deterioration of their characteristics and
cause them to break down. The temperature referred to here includes the ambient temperature within the
equipment, the heat produced by heat generating devices (power transistor, resistors, etc.), self-heating due to
ripple currents, etc. Take all of these factors into consideration when checking the capacitor’s temperature.
Do not place any heat generating devices on the back of the capacitors. Life acceleration can be
calculated with the following equation :
L2 = L1×2( )
L1 : Life at temperature T1 °C (h)
L2 : Life at temperature T2 °C (h)
T1 : Category s upper limit temperature
T2 : Ambient temperature to calculate the life + heat generation due to ripple current (°C)
✽ Humidity also affects the capacitor’s life. When using capacitors outside the following conditions, please contact us.
A temperature at +55 °C and a relative humidity of 90 % to 95% for 500 hours.
✽ The result that a very long term backup can be expected in calculation might be obtained by use conditions.
However, please consider checking regularly and exchanging it when using it for the set that long-term reliability is
basically demanded from the Gold Capacitor.
1.5 Voltage drop
Pay particular attention to the instantaneous working current and the voltage drop due to the capacitor’s
internal resistance when used in backup mode. The discharging current level is different depending on the
capacitor’s internal resistance. Use a capacitor with a discharging current below what is specified by the
corresponding capacitor.

1.6 Series connection
When connecting capacitors in series, add a bleeder resistor in parallel with each capacitor by taking the
leakage current into consideration so that the balance of voltages is not disrupted.
✽ Please present use condition about HZ/HW/HL series, and please contact us.
1.7 Electrolyte is used in the products
Electrolyte is used in the capacitors. Electrolyte leakage will damage printed circuit boards and can affect
their performance, characteristics, and functions.
1.8 External sleeve
The external sleeve is not electrical insulation, and thus capacitors should not be used in an environment
that requires electrical insulation. The sleeve is covered only for showing ratings.
2. Mounting
2.1 Heat stress at the soldering
When soldering a capacitor to a printed circuit board, excessive heat stress could cause the deterioration of
the capacitor’s electrical characteristics. For example the integrity of the seal can be compromised causing
the electrolyte to leak, and short circuits could occur in addition to and failure of the appearance.
Please observe the following guidelines.
(1) Manual soldering
Do not touch the capacitor body with a soldering iron. Solder the capacitor using a soldering tip temperature of
350 °C or less for 4 seconds or less. Solder a the capacitor three times or less at intervals of 15 seconds or more.
(2) Flow soldering
1) Do not dip the body of the products into a
soldering bath.
2) Keep the product’s surface temperature
at or below 100 °C for no more than
60 seconds (the peak 105 °C) when
soldering. Please refer to the chart at right
to set soldering temperature and time. It
is recommended to check the product
temperature before you use.
3) The terminals of the NF/F/RF/LF type
are designed so the bottom of the
product floats from the PWB. This is
to protect against heat stress during
soldering. Do not touch the bottom of the
product directly to the PWB.
(3) Other heat stress
1) Keep the product’s surface temperature
at or below 100 °C for no more than 60
seconds (the peak 105 °C) when applying
heat to bake the PWB or fixing resin, etc.The capacitor voltage must be 0.3 V or less.
2) Do not use a product more than once after it has been mounted on the PWB. Excessive heat stress is
applied when detaching it from the PWB. Please observe “(1) Manual soldering” when you adjusting it.
3) Be sure that excessive heat stress is not applied to the Gold capacitor when other parts in its
surroundings of the Gold capacitor are detached or adjusted.
(4) Others
1) The lead wires and terminals are plated for solderability. Rasping or filing lead wires or terminals
might damage the plating layer and degrade the solderability.
2) Do not apply a large mechanical force to the lead wires or terminals. Otherwise, they may break or
come off or the capacitor characteristics may be damaged.
3) There is a possibility that the sealing performance of the product is deteriorated if a coating material
that contains an organic solvent is used.
2.2 Circuit Design
Do not set wiring pattern directly under the mounted capacitor, and pass between terminals. If the
electrolyte leaks, short circuit might occur and tracking or migrations are anticipated. If a capacitor is
directly touching a PWB, then the bottom of the capacitorand the circuit pattern may short-circuit. On PWBs,
blowing flux or solder may cause the capacitor’s external sleeve to break or shrink, potentially affecting the
internal structure. In addition, please refer to application guidelines for the aluminum electrolytic capacitor.
2.3 Residual voltage
Gold Capacitors can hold a large charge and could have residual voltage. Therefore, some electronic
components with a low withstand voltage, such as semi-conductors, might be damaged.

(5) Capacitors are exposed to acidic or alkaline environments.
(6) Capacitors are subject to high-frequency induction.
(7)Capacitors are subject to excessive vibrations or mechanical impact.
A brown excretion might be caused around the sealing, depending on the conditions of use. This excretion is
insulation and does not. have influence on the electrical characteristics.
4. Maintenance Precautions
Periodically check capacitors used in industrial equipment. When checking and maintaining capacitors, turn off
the equipment and discharge the capacitors beforehand. Do not apply stress to the capacitor lead terminals.
Periodically check the following items.
1) Significant appearance abnormalities (deformation, electrolyte leakage, etc.)
2) Electrical characteristics (described in the catalog or delivery specifications)
If any abnormalities are found, then replace the capacitors or take appropriate actions.
5. Emergency procedures
If the capacitors generate heat, then smoke may come out of the exterior resin. Under these conditions turn off
the equipment immediately and stop using it.
Do not place your face or hands close to the capacitor, burns might be caused.
6. Storage
Do not store capacitors in a high-temperature or high-humidity environment. Store capacitors at a room
temperature of 5 to 35 °C and a relative humidity of 85 % or less. (Recommended storage term: 1year or less.)
Store capacitors in their packaging as long as possible. Avoid storing capacitors under the following conditions.
(1) Exposed to water, high temperatures or humidity, or when condensation can occurs.
(2) Exposed to oil or in environments filled with gaseous oil contents.
