- The component may be damaged if mechanical stress exceeding specifications is applied.
- Take care to protect the operating circuit from surge voltage resulting from excessive force, falling, shock or temperature change.
- Avoid excessive pulling of the lead wire because the wire may break or the soldering point come off.
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.
Preferred 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 products may be degraded in solderability due to storage under poor conditions.
Note:
Please confirm solderability and characteristics for the products regularly.
3. Notice on Product Storage
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, may be degraded in solderability due to storage in a chemical atmosphere.
