5.2 Storage Condition
The products should be stored in the room ,where the temperature/humidity is stable. And avoid such

places where there are large temperature changes. Please store the products at the foll-

owing conditions:
Temperature: -10 to + 40 C Humidity: 15 to 85% R.H.

5.3 Expire Date on Storage

Expire date (Shelf life) of the products is six months after deliveried under the conditions of a

sealed and an unopened package. Please use the products within six months after deliveried.
If you store the products for a long time (more than six months), use carefully because the
products may be degraded in the solderability and/or rusty.Please confirm solderability and
characteristics for the products regularly.

5.4 Notice on Product Storage

(1) Please do not store the products in a chemical atmosphere (Acids, Alkali, Bases, Organic

gas, Sulfides and so on), because the characteristics may be reduced at quality, and/or be d-

egraded in the solderability due to the storage in a chemical atmosphere.
(2) Please use the products immediately after the package is opened, because the character­istics may be reduced at quality, and/or be degraded in the solderability due to storage under

the poor condition.

(3) Please do not drop the products to avoid cracking of ceramic element.
