Charge/Discharge Cycle Test Condition
Characteristics
Please check the polarity before use. It will be damaged if it is reverse charged.
Direct contact with positive （ ＋） and negative （ー） terminals or connection with
metal or other conductive materials may cause short-circuit and excessive current
flow, which may cause heating and leakage.
Use beyond the rated voltage may cause not only reduced lifetime but also heating
or leakage in some cases.
Lithium ion capacitor is characterized by stability behavior in high temperature, but
operating temperature is recommended to be lower than the maximum operating
temperature, because use in low temperature extends its expected lifetime.
rent or that requires rapid and very frequent charge / discharge
In circuit with high ripple current or that requires rapid and very frequent charge /
discharge, the lifetime of lithium ion capacitors might be shortened by self-heating.
Please consult us in case of using lithium ion capacitor in such circuit.
When the discharge starts, voltage drop occurs if discharge current is high. Con-
sult us about the discharging current.
In case of using lithium ion capacitors in a series connection, the voltage may be
different in these capacitors, the difference of the voltages could shorten the life-
time of the capacitors or break them down.
Take a margin against a rated voltage or add a balancing resister
In case lithium ion capacitor is used in the high humidity, alkaline or acid air, it may
cause deteriorating of its performance and short circuit by corrosion of outer can
or lead terminal.
In addition, used in sudden temperature charge or high humidity, that may cause a
deterioration of its performance or a leakage by dew condensation.

9. Lithium ion capacitor has the pressure relief vent.
10. Do not apply shock or pressure
11. Do not apply excessive heat when soldering.
12. Consult us about cleaning condition when cleaning circuit-board after soldering.
13. Other Notice
In case of inside pressure of lithium ion capacitor excessively rising, the pressure
relief vent will be opened in order to release inner gas.
Following clearance should be made above the pressure relief vent.
Lithium ion capacitor is sensitive to shock. Do not drop lithium ion capacitor and
not apply strong pressure to a body, terminals and lead.
Soldering part or lead terminal will be damaged if applying vibration, shock and
stress such as pinch, tip, push and twist after mounting.
If excessive heat stress applied, electronic degradation or leakage might occur.
Do not solder over solder conditions in the spec. sheet.
Cleaning may affect lithium ion capacitor. Consult us about cleaning conditions
beforehand.
◦ Do not heat or throw into fire.
◦ Do not solder directly to a cell body.
◦ Do not dismantle.
