CERAMIC TYPE PAS CAPACITOR
■PRECAUTIONS
1. Use under the maximum usable voltage
When voltage which exceed the maximum usable voltage is applied, it might cause abnormal current flow, which shorten lifetime, and leakage , and sometimes
damages PAS capacitors.
2. Use under maximum operating temperature
A capacitor using in over max operating temperature may lead to shorter life, leakage, and electrical damage by increasing internal pressure.
3. Limited lifetime
Lifetime of PAS capacitor is greatly affected by surrounding temperature. If the temperature lowered by 10℃, the lifetime will approximately doubled. Design
a circuit under consideration of deterioration of electrical characteristics after long time usage, i.e. decrease in capacitance and increase in internal
resistance.
4. PAS capacitor's electrical characteristics might change depending on the surrounding temperature
PAS Capacitor’s electrical characteristics might change depending on the surrounding temperature aside from aged deterioration.
Therefore, be sure to confirm the temperature performance before use product.
5. PAS capacitor has polarity
PAS capacitor has polarity. Please check the polarity before use.
If a reverse voltage is applied, causing damage to the product.
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 will 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
capacitor, which may lead to shortening lifetime and breakdown. Take a margin against a rated voltage or add a balancing resistance.
9. Don’t contact with wiring pattern during installing
If PAS capacitor contact with wiring pattern, it may causes short-circuit, and if there is wiring pattern underneath of PAS capacitor, short circuit would
occur by damage of resist.
10. Environment of usage
In case PAS capacitor is used in high humidity, alkaline or acid air, it may cause deteriorating of its performance and short circuit by corrosion of outer can
or terminal. In addition, used in sudden temperature change or high humidity, it may cause deteriorating of its performance and electrolyte leak by dew
condensation.
11. Don’t apply shock and vibration or pressure
PAS capacitor is sensitive to shock. Don’t drop PAS capacitor and not apply strong pressure to a body, terminals. Soldering part or 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, and shortening lifetime.
・Don’t contact solder iron to a cell body.
・Don’t solder over solder conditions in the soldering test condition sheet.
・Don’t charge/discharge before reflow
13. Mind cleaning condition when cleaning circuit-board after soldering
Cleaning may affect PAS capacitor. Consult us about cleaning conditions beforehand.
Some cleaning conditions cause detrimental influence.
14. Storage
Keep following cautions for storage of PAS capacitor.
● Don’t store in high temperature and high humidity condition and a place where receiving direct sunlight. Storing PAS capacitor in the room condition of
10 ºC - 35 ºC and less than 65% relative humidity is recommended.
● Sudden temperature change or high humidity may cause deteriorating of its characteristics and soldering.
● Don’t store PAS capacitor near water, salt water or oil, and dew condensation, gasified oil or salinity filled place.
● Don’t store PAS capacitor in the hazardous gas (hydrogen sulfide, sulfurous, chlorine, ammonia, bromine, methyl bromine and etc.) .
● Don’t fumigate by halogen fumigant.
● Don’t store PAS capacitor near acid or alkaline solvent.
● Don’t store PAS capacitor in a place where exposed to ozone, ultraviolet or x-ray.
● Don’t store PAS capacitor in a place where vibration and shock might occur.
