9-7.Mounting density
Add special attention to radiating heat of products when mounting the inductor near the products with heating.
The excessive heat by other products may cause deterioration at joint of this product with substrate.
9-8. Operating Environment
Do not use this product under the following environmental conditions, on deterioration of the Insulation
Resistance of the Ferrite material and/or corrosion of Inner Electrode may result from the use.
(1) in the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and
etc. (the sea breeze, Cl2, H2S, NH3, SO2, NO2,etc)
(2) in the atmosphere where liquid such as organic solvent, may splash on the products.
(3) in the atmosphere where the temperature / humidity changes rapidly and it is easy to dew.
9-9. Resin coating
The impedance 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.
9-10. Cleaning
When cleaning this product, observe the following conditions.
Any cleaning may cause deterioration in the quality of the product, so please check the quality of this product
before use.
(1) The cleaning temperature shall be 60°C max. If isopropyl alcohol (IPA) is used, the cleaning temperature
shall be 40°C max.
(2) When ultrasonic cleaning is used, under some cleaning conditions, the substrate could resonate and the
substrate vibrations could result in chip cracks, solder breakage, and other problems. Be sure to always
perform a test cleaning beforehand using an actual cleaning device, and then check the quality of the products.
(3) Cleaner
Alcohol-based cleaner: IPA
Aqueous agent: PINE ALPHA ST-100S
(4) There shall be no residual flux or residual cleaner.
When using aqueous agent, rinse the product with deionized water adequately and completely dry it so that no
cleaner is left.
* For other cleaning, please consult our technical department.
9-11. 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
9-12.Storage Conditions
(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.
• Avoid storing the product by itself bare (i.e.exposed directly to air).
(3)Delivery
Care should be taken when transporting or handling product to avoid excessive vibration or mechanical
shock.
