65PWB31 data sheet dod-pd-0734 (2nd edition) 9 4.3.2 environment do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. in order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after leave under the environment of an unpacking room temperature enough. because a situation of dew condensation occurring is changed by the environmental temperature and humidity, evaluate the leaving time sufficiently. (recommendation leaving time: 6 hour or more with packing state) do not operate in high magnetic field. product may be broken down by it. this product is not designed as radiation hardened. 4.3.3 other all gndb and vddb terminals should be us ed without any non-connected lines. do not disassemble a product without permission of nec. pack the product with original shipping package, because of avoidance of some damages during transportation, when customer returns it to nec. put the spacer of 1.0mm thickness or more on a product rear side, because of the protection for contortion. e.g., washer condition: the washer thickness = 1.0mm (min.) the washer diameter ( ) = 5.0mm (recommendation)
