Reflow profile with lead free condition

Cautions : Do not charge prior to reflow,

Set reflow condition within the range provided in "Specifications", which will

be published separately.

1. Use under the maximum usable voltage.

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

which shorten lifetime, leakage 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.

Design a circuit under consideration of deterioration of electrical characteristics

after long time usage, decreasing in capacitance and increasing in internal resis-

tance.

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 damage

if it is reverse 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 back-up.

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. Don’tcontact with wiring pattern during installing

patternunderneathofPAScapacitor,shortcircuitwouldoccurbydamageofresist.

10.Environmental of usage.

In case PAS capacitor is used in high humidity, alkaline or acid air, it may cause deterio-

rating of its performance and short circuit by corrosion of outer can or lead terminal. In

addition, used in sudden temperature change or high humidity, it may cause deteriorat-

ing of its performance and electrolyte leak by dew condensation.

11. 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.

12.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.

◦ Don’tcharge/discharge before reflow.

※The use of the soldering iron is outside the guarantee of this product.

13.Mind 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.

14. Storage

Keep following cautions for storage of PAS capacitor

◦ Don’tstore in the high temperature and 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

temperature change or high humidity may cause deteriorating of its character-

istics 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.

15. Disposal

Dispose PAS capacitor in accordance with local and country rules and regulations.

16. Usage

PAS capacitor is developed on the assumption of the memory-backup & RTC for

usage of information & communication　equipment, home electronics, audio &

visual equipment, office equipment and etc. Consult us about using high reliability

and safety required products such as medical equipment, transportation equip-

ment, industrial equipment, flight / space equipment and emergency equipment.

17. Other Notice

◦ Don’theat or throw PAS capacitor into fire.

◦ Don’tshort circuit.

◦ Don’tsolder directly to a cell body.

◦ Don’topen a body.

◦ Don’tdeform.

◦ Don’tapply pressure.
