121PW161 data sheet dod-pd-0932 (1st edition) 8 4.3.2 environment do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. keep the product in packing box with antistatic pouch in room temperature to avoid dusts and sunlight, when storing the product. in order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after enough time being left under the environment of an unpacking room. evaluate the leaving time sufficiently because a situation of dew condensation occurring is changed by the environmental temperature and humidity. (r ecommended leaving time: 6 hours 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. pack the product with original shipping package, in order to avoid any damages during transportation, when returning the product to nec for repair and so on. put the spacer of 1.0mm thickness or more on a product rear side, because of the protection for contortion. spacer example: thickness= 1.0mm (min.) diameter ( ) = 5.0mm (recommendation)
