Operating Temperature : –20 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.
