hybrid ic VLA202-24051 dc-dc converter 4 for safety using great detail and careful attention are given to the pr oduction activity of hics, such as the development, the quality of production, and in it?s reliability. however the reliability of hics depends not only on their own factors but also in their conditi on of usage. when handling hics, please note the following cautions. cautions packing carrying storage extended storage maximum ratings polarity the materials used in packing hics can only withstand normal external conditions. when exposed to outside shocks, rain and cert ain environmental contaminators, the packing materials will deteriorates. please take care in handling. 1) don?t stack boxes too high. av oid placing heavy materials on boxes. 2) boxes must be positioned correctly during transportation to avoid breakage. 3) don't throw or drop boxes. 4) keep boxes dry. avoid rain or snow. 5) minimal vibration and shock dur ing transportation is desirable. when storing hics, please observe the following notic es or possible deteriorati on of their electrical characteristics, risk of solderability , and external damage may occur. 1) devices must be stored where fluctuation of temperature and humidity is minimal, and must not be exposed to direct sunlight. store at the normal temperature of 5 to 30 degrees celsius with humidity at 40 to 60%. 2) avoid locations where corrosive gasses are generated or where much dust accumulates. 3) storage cases must be static proof. 4) avoid putting weight on boxes. when extended storage is necessary, hics must be kept non-processed. when using hics which have been stored for more than one year or under severe conditions, be sure to check that the exterior is free from flaw and other damages. to prevent any electrical damages, use hics with in the maximum ratings. the temperaqture, current, voltage, etc. must not exceed these conditions. to protect hics from destruction and deterioration due to wrong insertion, make sure of polarity in inserting leads into the board holes, conforming to the external view for the terminal arrangement.
