Cautions : Do not charge prior to reflow,
■
1. Use under the maximum usable voltage.
2. Use under surrounding temperature kept as normal as possible.
3. Mind voltage drop when back-up.
4. Consult us when using PAS capacitors in a series connection.
5. Pay sufficient attention to use PAS in circuit with high ripple current.
6. Do not expose PAS capacitor into high humidity, alkaline or acid air.
7. Do not touch with printed pattern.

Cycle Characteristics
If over maximum usable voltage is applied, it might cause abnormal current flow
which shortens lifetime and sometimes damages PAS capacitor.
Lifetime of PAS capacitor is greatly affected by surrounding temperature. Each 10℃
drop in temperature extends its expected lifetime approximately twice as much.
Therefore, avoid high temperature and use PAS capacitor under lower temperature
than the maximum operating temperature range.
When the discharge starts, voltage drop occurs by actuating current and internal
resistance in the cell.
Consult us beforehand in case if discharging current of 311 type is over 10μA and
over 20μA for 409/414 type.
In case of using PAS capacitors in a series connection, the voltage may be differ-
ent in these capacitors, the difference of the voltages could shorten the lifetime of
the capacitors or break them down.
Since PAS capacitor has higher internal resistance than electric capacitor, ripple
current may heat up capacitor body, which might cause the increase of internal
resistance and deterioration of capacity.
In case PAS capacitor is used in high humidity, alkaline or acid air, lead terminal
and container may be damaged.
Also, it may cause deteriorating of its performance.
If product touches printed pattern, short-circuit occurs.
Additionally, if there is a printed pattern under the product, it may occur short-
circuit caused by a breakage of resist.
