Guidelines and precautions regarding the
technical information and use of our products
described in this online catalog.
■
If you want to use our products described in this online catalog for applications requiring special
qualities or reliability, or for applications where the failure or malfunction of the products may directly
jeopardize human life or potentially cause personal injury (e.g. aircraft and aerospace equipment,
traffic and transportation equipment, combustion equipment, medical equipment, accident prevention,
anti-crime equipment, and/or safety equipment), it is necessary to verify whether the specifications of
our products fit to such applications. Please ensure that you will ask and check with our inquiry desk
as to whether the specifications of our products fit to such applications use before you use our products.
■
The quality and performance of our products as described in this online catalog only apply to our
products when used in isolation. Therefore, please ensure you evaluate and verify our products under
the specific circumstances in which our products are assembled in your own products and in which our
products will actually be used.
■
If you use our products in equipment that requires a high degree of reliability, regardless of the
application, it is recommended that you set up protection circuits and redundancy circuits in order
to ensure safety of your equipment.
■
The products and product specifications described in this online catalog are subject to change for
improvement without prior notice. Therefore, please be sure to request and confirm the latest product
specifications which explain the specifications of our products in detail, before you finalize the design
of your applications, purchase, or use our products.
■
The technical information in this online catalog provides examples of our products' typical operations
and application circuits. We do not guarantee the non-infringement of third party's intellectual property
rights and we do not grant any license, right, or interest in our intellectual property.
■
If any of our products, product specifications and/or technical information in this online catalog is to
be exported or provided to non-residents, the laws and regulations of the exporting country,
especially with regard to security and export control, shall be observed.
<Regarding the Certificate of Compliance with
the EU RoHS Directive/REACH Regulations>
■
The switchover date for compliance with the RoHS Directive/REACH Regulations varies depending
on the part number or series of our products.
■
When you use the inventory of our products for which it is unclear whether those products are
compliant with the RoHS Directive/REACH Regulation, please select "Sales Inquiry" in the website
inquiry form and contact us.
We do not take any responsibility for the use of our products outside the scope of the
