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.
