10.2 Precautions on rating
Avoid using in exceeded the rated temperature range, rated voltage, or rated current.
Usage when the ratings are exceeded could lead to wire breakage, burning, or other serious fault.
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 Inrush current
If an inrush current (or pulse current or rush current) that significantly exceeds the rated current is applied to the product,
overheating could occur, resulting in wire breakage, burning, or other serious fault.
10.5 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.
Also, if repeatedly subjected to temperature cycles or other thermal stress, due to the difference in the coefficient of thermal
expansion with the mounting substrate, the solder (solder fillet part) in the mounting part may crack.
The occurrence of cracks due to thermal stress is affected by the size of the land where mounted, the solder volume, and
the heat dissipation of the mounting substrate. Carefully design it when a large change in ambient temperature is assumed.

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 200 μm
If you want to use a flux other than the above, please consult our technical department.
11.3 Soldering conditions (reflow)
• Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to
150°C max.
Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 100°C max.
Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of product quality.
• Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and/or resulting in the deterioration of
product quality.

It is effective to implement the following measures, to reduce stress in separating the board.
It is best to implement all of the following three measures; however, implement as many measures as possible to reduce
stress.
Contents of measures
Stress level
(1) Turn the mounting direction of the component parallel to the
board separation surface.
A > D*1
(2) Add slits in the board separation part.
A>B
(3) Keep the mounting position of the component away from the
board separation surface.
A>C
*1 A > D is valid when stress is added vertically to the perforation as with hand separation.
If a cutting disc is used, stress will be diagonal to the PCB, therefore A > D is invalid.

(3) Mounting components near screw holes
When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the
tightening of the screw.
Mount the component in a position as far away from the screw holes as possible.
11.7 Handling of substrate
After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the substrate
when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the substrate.
Excessive mechanical stress may cause cracking in the product.

11.9 Storage and transportation
Storage period
Use the product within 6 months after delivery.
If you do not use the product for more than 6 months, check solderability before using it.
Storage conditions
• The products shall be stored in a room not subject to rapid changes in temperature and
humidity. The recommended temperature range is -10°C to +40°C. The recommended relative
humidity range is 15% to 85%.
Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid may cause the
poor solderability.
• Do not place the products directly on the floor; they should be placed on a palette so that they
are not affected by humidity or dust.
• Avoid keeping the products in a place exposed to direct sunlight, heat or vibration.
• Do not keep products in bulk packaging. Bulk storage could result in collisions between the
products or between the products and other parts, resulting in chipping or wire breakage.
• Avoid storing the product by itself bare (i.e. exposed directly to air).
Transportation
Excessive vibration and impact reduces the reliability of the products. Exercise caution when
handling the products.
11.10 Resin coating (including moisture-proof coating)
When the product is coated/molded with resin, its electrical characteristics may change.
A wire breakage issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating
condition etc.
Some resins contain impurities or hydrolyzable chlorine, which could result in corrosion of the conducting materials, leading
to wire breakage.
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.
