Caution
10.1 Restricted applications
Please contact us before using our products for the applications listed below which require especially high reliability for the
prevention of defects which might directly cause damage to the third party's life, body or property.
(1) Aircraft equipment
(6) Disaster/crime prevention equipment
(7) Traffic signal equipment
(2) Aerospace equipment
(3) Undersea equipment
(4) Power plant control equipment
(5) Medical equipment
(8) Transportation equipment (trains, ships, etc.)
(9) Data-processing equipment
(10) Applications of similar complexity and/or reliability requirements
to the applications listed in the above
10.2 Precautions on rating
Do not use the products in excess of their rated current. Doing so may cause the product to generate heat, resulting in short
circuit between wires, wire breakage, or melted solder, which may cause dropping of parts.
10.3 Fail-safe
Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the
abnormal function or the failure of our product.
10.4 Corrosive gas
Please refrain from use since contact with environments with corrosive gases (sulfur gas [hydrogen sulfide, sulfur dioxide,
etc.], chlorine, ammonia, etc.) or oils (cutting oil, silicone oil, etc.) that have come into contact with the previously stated
corrosive gas environment will result in deterioration of product quality or an open from deterioration due to corrosion of
product electrode, etc. We will not bear any responsibility for use under these environments.
11. Precautions for Use
This product is for use only with reflow soldering. It is designed to be mounted by soldering. If you want to use other
mounting method, for example, using a conductive adhesive, please consult us beforehand.
11.1 Land dimensions
The following diagram shows the recommended land dimensions for reflow soldering.
The land dimensions are designed in consideration of electrical characteristics and mountability. Use of other land
dimensions may preclude achievement of performance. In some cases, it may result in poor solderability, including positional
shift. If you use other land pattern, consider it adequately.

11.2 Flux and solder used
Flux
• Use a rosin-based flux.
• Do not use a highly acidic flux with a halide content exceeding 0.2(wt)% (chlorine conversion value).
• Do not use a water-soluble flux.
Solder
• Use Sn-3.0Ag-0.5Cu solder.
• Standard thickness of solder paste: 100 μm to 150 μm
If you want to use a flux other than the above, please consult our technical department.
