16 Application Notes

16.1 Safety Precautions

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 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 provide the following failsafe functions as a minimum:

(1) Ensure the safety of the whole system by installing a protection circuit and a protection

device.

(2) Ensure the safety of the whole system by installing a redundant circuit or another

system to prevent a single fault causing an unsafe status.

16.2 Design Engineering Notes

(1) 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.

(2) Failure to do so may result in degrading of the product’s functions and damage to the

product.

(3) 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.

(4) These products are not intended for other uses, other than under the special conditions

shown below. Before using these products under such special conditions, check their

performance and reliability under the said special conditions carefully, to determine

whether or not they can be used in such a manner.
