Please store the products in room where the temperature/humidity is stable and direct sunlight is protected, Please use the products within 6 months after the delivery. Please consider to handle the products of MSL 3 which is capable within 168hours for soldering after the package opened. After the package is opened, if the products are stored longer than 168hours without soldering, please store them in 10%RH or less, and 35 degree C or less of atmosphere. In case that the products are not stored such atmosphere, please bake at 125 degree C for 24hours before they are used. However please do it after take them out from packaging material. Because the material of the package will be thermally distorted on this baking temperature. If baking should be done with keeping them in the package, please bake them 40 degree C for 192 hours or 60 degree C for 168 hours. Please avoid to storing the products in the place where water condensation may be occurred. It is easy to water condensation in heated dump air in which large temperature changes may condense water. Otherwise, the quality of characteristics may be reduced, and also the solderability may be degraded. 13.3.2. Please do not store the products in the places such as : in a dusty place, in a place exposed directly to sea breeze, in an atmosphere containing corrosive gas (Cl2,NH3,SO2,NOX and so on). 13.4. Operational Environment and Operational Conditions 13.4.1. Operational Environment The products are not waterproof, chemical-proof or rustproof. In order to prevent leakage of electricity and abnormal temperature increase of the products, do not use the products under the following circumstances: (1) in an atmosphere containing corrosive gas (Cl2, NH3, SO2, NOX and so on) (2) in a dusty place (3) in a place exposed to direct sunlight (4) in such a place where water splashes or in such a humid place where water condenses (5) in a place exposed to sea breeze (6) in any other places similar to the above (1)through (5) 13.4.2. Operational Conditions Please use the products within specified values (power supply, temperature, input, output and load condition, and so on). Please make sure that input voltage is in specified values. Input voltage may be changed by line impedance change etc. If the product is used out of the specified values, the product may be broken, the quality is reduced, and even if the products can endure the condition for short time, it may cause degradation of the reliability. 13.4.3.
