Caution
13.1 Mounting Direction
Mount products in right direction.
Wrong direction which is 90°rotated from right direction causes not only open or short circuit but also
flames or other serious trouble.
13.2 Limitation of 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) Transportation equipment (trains, ships, etc.)
(2) Aerospace equipment (7) Traffic signal equipment
(3) Undersea equipment (8) Disaster prevention / crime prevention equipment
(4) Power plant control equipment (9) Data-processing equipment
(5) Medical equipment (10) Applications of similar complexity and / or reliability requirements
to the applications listed in the above.
13.3 Caution(Rating)
Do not exceed maximum rated current of the product. Thermal stress may be transmitted to the product and
short/open circuit of the product or falling off the product may be occurred.
13.4 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.
14. Notice
Products can only be soldered with reflow.
This product is designed for solder mounting.
Please consult us in advance for applying other mounting method such as conductive adhesive.
14.1 Flux and Solder
Flux Use rosin-based flux,(with converting chlorine content 0.06 to 0.1(wt)%. ),
but not highly acidic flux
(with Halogen content exceeding 0.2(wt)% conversion to chlorine).
Do not use water-soluble flux.
Solder Use Sn-3.0Ag-0.5Cu solder
14.2 Assembling
<Exclusive use of Reflow soldering>
Flow soldering may cause deterioration in insulation resistance.
So, reflow soldering shall be applied for this product.
14.3 Cleaning Conditions
Do not clean after soldering. Some cleaning agents may degrade bonding strength,and
characteristics of products by detaching. If cleaning,please contact us.
14.4 Resin coating
The impedance value may change due to high cure-stress of resin to be used for coating/molding products. An open
circuit issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating
condition etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under
some operating condition may cause corrosion of wire of coil, leading to open circuit. So, please pay your careful
attention when you select resin in case of coating/molding the products with the resin. Prior to use the coating resin,
please make sure no reliability issue is observed by evaluating products mounted on your board.
