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 Refer 27 and 28 page. ■Soldering Conditions Refer 29 page. ■Safety Precautions Refer 30 page. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
