1. Use under the maximum usable voltage

If over maximum usable voltage is applied, it might cause abnormal current flow,

which shorten lifetime and sometimes damage PAS capacitor.

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.

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.

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.

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.

7. Mind voltage drop when discharging

When back-up (discharging) starts, voltage drop because of active current and

internal resistance.

8. Series connection

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.

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

18：over 2mm, Diameter≧φ18：over 3mm) should be made above the pressure

release vent.

Don’tset 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.

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. Don’tapply shock and vibration or pressure

PAS capacitor is sensitive to shock. Don’tdrop 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.

13. Soldering

If next each item is not minded, it may cause deteriorating of its performance,

leakage, shortening lifetime.

◦ Don’tcontact solder iron to a cell body.

◦ Don’tsolder 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.

15. Storage

Keep following cautions for storage of PAS capacitor.

◦ Don’tstore in the high temperature, the high humidity condition and a place

where receiving direct sunlight. Storing PAS capacitor in the room condition of

10℃ - 35℃ and less than 65% relative humidity is recommended. Sudden tem-

perature change or high humidity may cause deteriorating of its characteristics

and Soldering.

◦ Don’tstore PAS capacitor near water, salt water or oil, and it the dew conden-

sation, gasified oil or salinity filled place.

◦ Don’tstore PAS capacitor in the hazardous gas (hydrogen sulfide, sulfurous,

chlorine , ammonia, bromine, methyl bromine and etc).

◦ Don’tfumigate by halogen fumigant.

◦ Don’tstore PAS capacitor near acid or alkaline solvent.

◦ Don’tstore PAS capacitor in a place where exposed to ozone, ultraviolet or

x-ray.

◦ Don’tstore 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.

17. Usage

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.

18. Other Notice

◦ Don’theat or throw PAS capacitor into fire.

◦ Don’tshort.

◦ Don’tsolder directly to a cell body.

◦ Don’topen a body

◦ Don’tdeform.

◦ Don’tapply pressure.
