11.8 Resin coating
The inductance value may change and/or it may affect on the product's performance due to high
cure-stress of resin to be used for coating/molding products. So please pay your careful attention when you
select resin.
In prior to use, please make the reliability evaluation with the product mounted in your application set.
11.9 Caution for use
There is possibility that the inductance value change due to magnetism. Don‘t use a magnet or a pair of
tweezers with magnetism when chip coil are handled. (The tip of the tweezers should be molded with resin or
pottery.)
11.10 Magnetic Saturation
When the excessive current over rated current is applied, the inductance value may change due to
magnetism.
11.11 Handling of a 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.
Bending Twisting
11.12 Storage and Handing Requirements
(1) Storage period
Use the products within 6 months after delivered.
Solderability should be checked if this period is exceeded.
(2) Storage conditions
・Products should be stored in the warehouse on the following conditions.
Temperature : -10°C to 40°C
Humidity
: 15% to 85% relative humidity No rapid change on temperature and humidity
Don't keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may cause oxidization
of electrode, resulting in poor solderability.
・Products should be stored on the palette for the prevention of the influence from humidity, dust and so
on.
・Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on.
・Products should be stored under the airtight packaged condition.
(3) Handling Condition
Care should be taken when transporting or handling product to avoid excessive vibration or mechanical
shock.
