⚠️
Notice (Handling)
- 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.

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.
- Temperature: -10 to + 40°C
- Humidity: 15 to 85% R.H.
2. Expiration Date on Storage
Shelf life is six months after delivery in a sealed, unopened package. If stored longer than six months, check solderability carefully as quality may degrade.
3. Notice on Product Storage
Do not store in chemical atmospheres (Acids, Alkali, Bases, Organic gas, Sulfides, etc.), as this may reduce quality and degrade solderability.
