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 (2)Aerospace equipment (3)Undersea equipment (4)Power plant control equipment
(5)Medical equipment (6)Transportation equipment(automobiles, trains, ships, etc.) (7)Traffic signal equipment

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
Solder
Use rosin-based flux.
(with Halogen content exceeding 0.2(wt)% conversion to chlorine).
Do not use water-soluble flux.
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.
< Thermal Shock >
Pre-heating should be in such a way that the temperature difference between solder and
ceramic surface is limited to 100°C max. Also cooling into solvent after soldering
should be in such a way that the temperature difference is limited to 100°C max.
Not enough preheating may cause deterioration in insulation resistance and / or crank or ceramic body.
14.3 Cleaning Conditions
Do not clean after soldering. 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.
14.5 Attention regarding P.C.B. bending
The following shall be considered when designing and laying out P.C.B.'s.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress due to warping the board.
