１．Precautions in use① Please do not use the capacitor under the environment, which exceeds the rated performance range.
a)High temperature (over operating temperature)b)Over voltage (over rated voltage)c)Application of reverse or alternate voltage② The outer sleeve and resin plate of the Supercapacitor does not assure electrical insulation.
③ Supercapacitor has finite and regulated life.
④ Please do not use or store Supercapacitor under the following environment;a)Environment where the capacitor could be exposed to water, salt water or oil, or the environment which is filled with gaseous oilor salt.
b)Environment which is filled with toxic gases such as hydrogen sulfide, sulfurous acid, chlorine, ammonia, bromine, or methylbromide.
c)Environment where the capacitor could be exposed to acidic or alkaline solvent.
d)Environment where the capacitor could be exposed to direct sunlight, ozone, ultraviolet rays or radiation.
e)Environment under extreme vibration or mechanical impact.
⑤ Please note the followings when designing;a)Supercapacitor screw terminal When using cells and modules, be sure to install the terminal with the terminal facing upward
except for horizontal product.
Do not mount Supercapacitor with terminals facing downward or sideways as the electrolyte inside the Supercapacitor may
block pressure relief vent and cause it to open, electrolyte to leak, and shorten lifetime.
Please set the valve is on the upper side when used horizontally.

Figure. Installation of horizontal productsb)Please keep the sealing plate facing upward whenever handling Supercapacitor.
Facing it downward even for a brief time may shorten lifetime.
c)Please provide enough clearance space over the pressure relief vent.
d)Please do not locate any wire or circuit pattern over the pressure relief vent or between the anode and cathode terminal ofSupercapacitor.
e)Please avoid locating any heat source components near Supercapacitor.
f)To assure insulation voltage, please provide adequate space among Supercapacitor case, cathode terminal, anode terminal,
circuit pattern and chassis.
g)Please note that electrical properties of Supercapacitor may change according to the changes in temperature and frequency ofSupercapacitor.
h)When the temperature between Supercapacitor cells in a same system differs largely, it may amplify the slight characteristic
difference of each cell, and may cause the system to malfunction in the end.
Please make sure to design the system with an adequate heat radiation to avoid variation in temperature among the cells.
i)When heat increase is expected due to charging and discharging of Supercapacitor, please conduct a load test to confirm there
is no abnormal heat rise, and the temperateture stays within the Supercapacitor's specified temperature range.

SUPERCAPACITORj)Please assure appropriate current balance when connecting two or more Supercapacitor in parallel.
k)Please assure appropriate voltage balance when connecting two or more Supercapacitor in series.
l)In case of use outside of specification, such as overvoltage and/or above specified temperature range, the electrolyte fume frominside may expelled through releasing valve. Please take that in consideration at the time of system design.
m)Please establish safety design such as stopping charge/discharge in case of abnormal temperature and voltage. Applying
voltage that exceeds rated voltage frequently may cause the devices to smoke or burn.
Please design the system with fail-safe functions.
n)As Supercapacitor has internal resistance, the internal heat generated by charge-discharge affects its life.
Please choose the products with low resistance and make sure to avoid overheat of the capacitor.
o)Due to capacitor's internal resistance, there is a voltage drop (also referred to as "IR drop")
at the beginning of charge-discharge. Please consider this voltage drop in your circuit design.
⑥ When a capacitor is fully charged, short-circuiting the output terminals could cause the electric current to flow as high as a few hundredamperes. Please do not install or uninstall a module when it is charged.
⑦ Please do not drop Supercapacitor. Do not use it once it is dropped.
⑧ Please make sure of the polarity when assembling Supercapacitor into a module.
⑨ When assembling Supercapacitor into a circuit, position it so that the case and the circuit electronic components do not come in contact
with each other.
⑩ Please follow the specification of the screw tightening torque.
⑪ Please do not deform Supercapacitor when assembling it into a module.
⑫ Voltage of Supercapacitor changes in proportion to the stored energy.
If stable output voltage is required, circuit system such as converter needs to be added.
⑬ When using Supercapacitor for industrial application, following periodical check is recommended.
Please disconnect power from the device and fully discharge Supercapacitor before conducting periodical check.
a)Appearance: Significant damage in appearance including deformation, liquid leakage, discolor, dust between the terminals andstainb)Electrical characteristics: Characteristics prescribed in the catalog or product specifications.
⑭ Please stop the whole system when Supercapacitor generates excessive heat or a foul smell.
In case of excessive heat, do not get close to the part in order to avoid injury.
⑮ Please stop the system immediately and ventilate the area sufficiently when the pressure relief vent on Supercapacitor operates andreleases a gas from inside.
Never expose your face or your hand as hot gas may expel.
If the gas is inhaled or hits eyes, please wash your eyes, gargle, and consult with a doctor immediately.
Do not lick the electrolyte of Supercapacitor. Wash away the electrolyte from the skin with soap and water.
⑯ Supercapacitor may have been spontaneously recharged with time by a recovery voltage phenomenon.
Discharge Supercapacitor as necessary especially before connecting multiple Supercapacitors in series.
⑰ Please discharge Supercapacitor before assembling or removing. There is a risk of large current flow and electrical shock when shortcircuiting the terminal with residual voltage.
Note that Supercapacitor may be self-charged while being left open-circuit even after fully discharged.
⑱ Do not wash Supercapacitor.
⑲ Do not use any adhesive or coating materials containing halogenated solvents.
Additional notes about products with lead terminalsa)Align the distance between the capacitor terminals with the distance between the printed wiring board holes. (If the distances
differ, use a lead forming processed product.)b)Provide clearance space specified below at the section over the capacitor pressure relief vent.
φ 8 (6.3) to φ 16 2 mm or more
φ 18 to φ 22: 2.5 mm or morec)Ensure that no wire or circuit patterns are placed over the capacitor pressure relief vent.
If the capacitor pressure valve is attached to the printed wiring board side, create an air release hole for the pressure relief venttaking the location of the pressure valve into consideration.
