Storage Conditions
Package
: 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 : –40 to +85 °C
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 Methods, Soldering Conditions and Safety Precautions Please see Data Files.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
