Notice — Handling
- 1 The component may be damaged if mechanical stress exceeding specifications is applied.
- 2 Take care to protect the operating circuit from surge voltage resulting from excessive force, falling, shock or temperature change.
- 3 Avoid excessive pulling of the lead wire because the wire may break or the soldering point come off.
Notice — Storage and Operating Condition
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 products may be degraded in solderability due to storage under poor conditions. 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.
