When using our products, the following precautions should
be taken.
（1） Safety designing of an apparatus or a system allowing for failures of electronic components used
in the system
In general, failures will occur in electronic components at a certain probability. NEC TOKIN makes
every effort to improve the quality and reliability of electronic component products. However, it is
impossible to completely eliminate the probability of failures. Therefore, when using NEC TOKIN’
s electronic component products, systems should be carefully designed to ensure redundancy in
the event of an accident which would result in injury or death, fire, or social damage, to ensure
the prevention of the spread of fire, and the prevention of faulty operation. （Please refer to pre-
cautions to be taken when using multilayer piezoelectric actuators for the details of failures.）
（2） Quality level of various kinds of parts, and equipment in which the parts can be utilized
Electronic components have a standard quality level unless otherwise specified.
NEC TOKIN classifies the level of quality of electronic component products into three levels, in
order from a lower level, a standard quality level, a special quality level, and a custom quality level
in which a customer individually specifies a quality assurance program. Each of the quality levels
has recommended applications.
If a user wants to use the electronic parts having a standard quality level in applications other
than the applications specified for the standard quality level, they should always consult a member
of our company’s sales staff before using the electronic parts.
Standard quality level
: Computers, office automation equipment, communications equipment,
measuring instruments, AV equipment, household electrical appliances,
machine tools, personal equipment, industrial robots
Special quality level
: Transportation equipment（automobiles, railways, shipping, or the
like）, traffic signals, disaster prevention/crime prevention systems, a
variety of safety devices, and medical equipment which is not directly
intended for life-support purposes
Custom quality level
: Equipment for airplanes, aerospace equipment, nuclear power control
systems, and medical equipment, apparatus or system for life-support
purposes
Unless otherwise shown, the quality level of NEC TOKIN’s electronic component products included in
documents such as catalogues, data sheets or data books is the standard quality level.
