o Storage and Operating Conditions

1. Product Storage Condition

Please store the products in a room where the

temperature/humidity is stable, and avoid places where

there are large temperature changes. Please store the

products under the following conditions:

Temperature: -10 to + 40°C

Humidity: 15 to 85% R.H.

2. Expiration Date on Storage

Expiration date (shelf life) of the products is six months

after delivery under the conditions of a sealed and

unopened package. Please use the products within six

months after delivery. If you store the products for a long

time (more than six months), use carefully because the

solderability may be degraded due to storage under poor

conditions.

Please confirm solderability and characteristics for the

products regularly.

3. 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 in quality and may be degraded in

solderability due to storage in a chemical atmosphere.

(2) Please do not put the products directly on the floor

without anything under them to avoid damp places

and/or dusty places.

(3) Please do not store the products in places such as a

damp heated place or any place exposed to direct

sunlight or excessive vibration.

(4) Please use the products immediately after the

package is opened, because the characteristics may

be reduced in quality and/or be degraded in

solderability due to storage under poor condition.

(5) Please do not drop the products to avoid cracking of

ceramic element.

4. Other

Please be sure to consult with our sales representative or

engineer whenever the products are to be used in

conditions not listed above.
