FOR SAFETY USING
Great detail and careful attention are given to the production 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 condition of usage.
When handling Hics, please note the following cautions.
CAUTIONS
Packing
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.
Carrying
Storage
1) Don’t stack boxes too high. Avoid 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 during transportation is desirable.
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
Polarity
To prevent any electrical damages, use Hics within the maximum ratings. The temperature,
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.
