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.

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.

Safety precautions
• When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifications with us in advance. The design and specifications in this catalog are subject to
change without prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products under the actual conditions for use.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as
damage to vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment,
electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention
equipment.
½
Systems equipped with a protection circuit and a protection device.
½
Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault.
½
Systems equipped with an arresting the spread of fire or preventing glitch.
Precautions for use
• These products are designed and manufactured for general and standard use in general elec tron ic equipment.
(e.g. AV equipment, home electric appliances, office equipment, information and communication equipment)
For applications in which special quality and reliability are required, or if the failure or malfunction of the
products may directly jeopardize life or cause threat of personal injury (such as for aircraft and aerospace
equipment, traffic and transport equipment, combustion equipment, medical equipment, accident prevention
and anti-theft devices, and safety equipment), please be sure to consult with our sales representative in
advance and to exchange product specifications which conform to such applications.
• These products are not intended for use in the following special conditions. Before using the products, carefully
check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent.
2. In direct sunlight, outdoors, or in dust.
3. In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX .
4. Electric Static Discharge (ESD) Environment.
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.
5. Electromagnetic and Radioactive Environment.
Avoid any environment where strong electromagnetic waves and radiation exist.
6. In an environment where these products cause dew condensation.
7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials.
• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range
due to the effects of neighboring heat-generating components. Do not mount or place heat-generating
components or inflammables, such as vinyl-coated wires, near these products.
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the
performance or reliability of the products.
• Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the
performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to
leave water residues. Otherwise, the insulation performance may be deteriorated.
• Do not apply flux to these products after soldering. The activity of flux may be a cause of failures in these
products.
• Refer to the recommended soldering conditions and set the soldering condition. High peak temperature or
long heating time may impair the performance or the reliability of these products.
• Recommended soldering condition is for the guideline for ensuring the basic characteristics of the products,
not for the stable soldering conditions. Conditions for proper soldering should be set up according to individual
conditions.
• Do not reuse any products after removal from mounting boards.
• Do not drop these products. If these products are dropped, do not use them. Such products may have
received mechanical or electrical damage.
• If any doubt or concern to the safety on these products arise, make sure to inform us immediately and
conduct technical examinations at your side.
