However the reliability of Hics depends not only on their own factors but also in their condition of usage. When handling Hics, please note the following cautions. CAUTIONS Packing Carrying The materials used in packing Hics can only withstand normal external conditions. When exposed to outside shocks, rain and certain environmental contaminators, the packing materials will deteriorates. Please take care in handling. 1) 2) 3) 4) 5) Don’t stack boxes too high. Avoid placing heavy materials on boxes. Boxes must be positioned correctly during transportation to avoid breakage. Don't throw or drop boxes. Keep boxes dry. Avoid rain or snow. Minimal vibration and shock during transportation is desirable. Storage When storing Hics, please observe the following notices or possible deterioration 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. Extended storage 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. Maximum ratings To prevent any electrical damages, use Hics within the maximum ratings. current, voltage, etc. must not exceed these conditions. Polarity 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. 6 The temperature, HYBRID IC VLA315-24100 ISOLATED TYPE DC-DC CONVERTER Marketing division, Marketing planning department 6-41 Tsukuba, Isahaya, Nagasaki, 854-0065 Japan Keep safety first in your circuit designs! ・ISAHAYA Electronics Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them.
