Keep Safety first in your circuit designs!
Mitsubishi Electric 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.
Trouble with semiconductors may lead to personal
injury , fire or property damage. Remember to give
due consideration to safety when making your
circuit designs , with appropriate measure such
as (I) placement of substitutive , auxiliary circuits ,
(ii) use of non-flammable material or (iii) prevention
against any malfunction or mishap.
