CYLINDER TYPE PAS CAPACITOR
■ PRECAUTIONS
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. Design 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 damaged 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
capacitor, 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’t 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.
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’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 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’t contact solder iron to a cell body.
● Don’t 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 beforehand.
Some cleaning conditions cause detrimental influence.
