PRECAUTIONS  
1. Use under the maximum usable voltage  
13. Soldering  
If over maximum usable voltage is applied, it might cause abnormal current flow,  
which shorten lifetime and sometimes damage PAS capacitor.  
If next each item is not minded, it may cause deteriorating of its performance,  
leakage, shortening lifetime.  
Dont contact solder iron to a cell body.  
2. Use under maximum operating temperature  
Not only shorter life time but also leakage and damage will happen by increasing  
internal pressure if PAS capacitor use in over max operating temperature.  
Dont solder over solder conditions in the spec sheet.  
14. Cleaning condition when cleaning circuit-board after soldering  
Cleaning may affect PAS capacitor. Consult us about cleaning conditions before-  
hand. Some cleaning conditions cause detrimental influence.  
3. Limited life time  
Lifetime of PAS capacitor is greatly affected by surrounding temperature. 10℃  
drop in temperature extend its expected lifetime approximately twice as much. De-  
sign a circuit under consideration of deterioration of electrical characteristics after  
long time usage, decreasing in capacitance and increasing in internal resistance.  
15. Storage  
Keep following cautions for storage of PAS capacitor.  
Dont store in the high temperature, the high humidity condition and a place  
where receiving direct sunlight. Storing PAS capacitor in the room condition of  
10- 35and less than 65% relative humidity is recommended. Sudden tem-  
perature change or high humidity may cause deteriorating of its characteristics  
and Soldering.  
Dont store PAS capacitor near water, salt water or oil, and it the dew conden-  
sation, gasified oil or salinity filled place.  
Dont store PAS capacitor in the hazardous gas (hydrogen sulfide, sulfurous,  
chlorine , ammonia, bromine, methyl bromine and etc).  
4. The electrical characteristics of capacitors vary with respect to temperature  
The electrical characteristics of PAS capacitors temporarily vary with respect to  
temperature separately from secular change mentioned above. Design a circuit  
under consideration of temperature characteristics.  
5. PAS capacitor has polarity  
PAS capacitor has polarity. Please check the polarity before use. It will be dam-  
aged if it is reversely charged.  
Dont fumigate by halogen fumigant.  
6. Mind high ripple current or rapid charge / discharge  
In circuit with high ripple current or rapid charge / discharge, the lifetime of PAS  
capacitors might be shortened by self-heating.  
Dont store PAS capacitor near acid or alkaline solvent.  
Dont store PAS capacitor in a place where exposed to ozone, ultraviolet or  
x-ray.  
7. Mind voltage drop when discharging  
When back-up (discharging) starts, voltage drop because of active current and  
internal resistance.  
Dont store PAS capacitor in a place where vibration and shock might occur in.  
16. Disposal  
Dispose PAS capacitor in accordance with local and country rules and regulations.  
8. Series connection  
17. Usage  
In case of using PAS capacitor in series connection, the voltage of each capacitor  
is not always equal and it may be occurred excessive voltage in a part of capaci-  
tor, which may lead to shortening lifetime and breakdown. Take a margin against a  
rated voltage or add a balancing resister.  
PAS capacitor is developed on the assumption of the memory-backup & RTC for  
usage of information & communication equipment, home electronics, audio & visu-  
al equipment, office equipment and etc. Consult us about using high reliability and  
safety required products such as medical equipment, transportation equipment,  
industrial equipment, flight / space equipment and emergency equipment.  
9. PAS capacitor has the pressure release vent  
In case of inside pressure of capacitor excessively rising, the pressure release vent  
will be opened in order to release inner gas. Following clearance (Diameter<φ  
18over 2mm, Diameter≧φ18over 3mm) should be made above the pressure  
release vent.  
Dont set up wiring or a pattern in the upper part of the pressure release vent, so  
that the high temperature gas is gushed when the pressure release vent open.  
The product which open the pressure release vent can not use.  
18. Other Notice  
Dont heat or throw PAS capacitor into fire.  
Dont short.  
Dont solder directly to a cell body.  
Dont open a body  
Dont deform.  
Dont apply pressure.  
10. The sleeve of the PAS capacitor is not guaranteed insulation  
Short circuit might happen if circuit pattern is set underneath of PAS capacitor or  
it fixed by a metal or it contact with other component.  
11. Environmental of usage  
In case PAS capacitor is used in the high humidity, alkaline or acid air, it may cause  
deterioration of its performance, electrolyte leak and short circuit by corrosion of  
outer can or lead terminal.  
In addition, used in sudden temperature change or high humidity, it may cause  
deteriorating of its performance and electrolyte leak by dew condensation.  
12. Dont apply shock and vibration or pressure  
PAS capacitor is sensitive to shock. Dont drop PAS capacitor and not apply  
strong pressure to a body, terminals and lead. Soldering part or lead terminal  
might be damaged if applying vibration, shock and stress such as pinch, tip, push  
and twist after installed.
