These specifications are intended to preserve the quality assurance of products as individual
components.
Before use, check and evaluate their operation when mounted on your products. Abide by
these specifications, without deviation when using the products. These products may short-
circuit. If electrical shocks, smoke, fire, and/or accidents involving human life are anticipated
when a short circuit occurs, then at least, provide the following failsafe functions, as a
minimum:
(1)
(2)

Ensure the safety of the whole system by installing a protection circuit and a protection
device.
Ensure the safety of the whole system by installing a redundant circuit or another
system to prevent a single fault causing an unsafe status.
Heat is the major cause of shortening the life of these products. Avoid assembly and
use of the target equipment in conditions where the product’s temperature may exceed
the maximum allowable.
Failure to do so may result in degrading of the product’s functions and damage to the
product.
If pulses or other transient loads (a large load applied in a short time) are applied to the
products, before use, check and evaluate their operation when assembled onto your
products.
