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). 12.4.2 Operational Conditions Please use the products within specified values (power supply, temperature, input, output and load condition, and so on). Input voltage drop for line impedance, so please make sure that input voltage is included in specified values. If you use the products over the specified values, it may break the products, reduce the quality, and even if the products can endure the condition for short time, it may cause degradation of the reliability. Also please take care that the external voltage over output voltage of DC-DC Converter does not applies to output of this DC-DC Converter. 12.4.3 Note prior to use If you apply high static electricity, over rated voltage or reverse voltage to the products, it may cause defects in the products or degrade the reliability. Please avoid the following items: (1) over rating power supply, reverse power supply or not-enough connection of 0 V(DC) line. (2) electrostatic discharge by production line and/or operator. (3) electrified product by electrostatic induction. Do not give an excessive mechanical shock.. If you drop the products on the floor, etc., it may occur a crack to the core of inductors and monolithic ceramic capacitors. Do not give a strong shock such as a drop in handling. 12.5 Transportation If you transport the products, please pack them so that the package will not be damaged by mechanical vibration or mechanical shock, and please educate and guide a carrier to prevent rough handling. If you transport the products to overseas (in particular, by sea), it is expected that the transportation environment will be the worst, so please pack the products, in the package designed on the consideration of mechanical strength, vibration-resistant and humidity-resistant. The package of the products which Murata sells in Japan, may not resist over seas transport. Please consult us if you are to use the Murata package of the products sold in Japan for transport to overseas. Note: 1.
