Storage Conditions
: Normal temperature (-5 to 35 C), normal humidity (85 %RH max.), shall not be exposed to direct sunlight and harmful gases and care should be taken so as not to cause dew. Operating Temperature : -20 to +85 C Package
Storage Period
Solderability may be reduced due to the conditions of high temperature and high humidity which causes the oxidation of tin-plated terminals. Even if storage conditions are within specified limits, solderability may be reduced with the passage of time. Therefore, please control the storage conditions and try to use the product within 6 months of receipt.
Packaging Soldering Conditions Safety Precautions
Refer 27 and 28 page. Refer 29 page. Refer 30 page.
