10-7.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 (acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and 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.
10-8.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.
10-9.Cleaning Conditions
Products shall be cleaned on the following conditions.
(1)Cleaning temperature shall be limited to 60°C max. (40°C max. for IPA.)
(2)Ultrasonic cleaning shall comply with the following conditions, avoiding the resonance phenomenon
at the mounted products and P.C.B.
Power:20W/ max. Frequency:28kHz to 40kHz Time:5 min max.
(3)Cleaner
1.Alternative cleaner
•Isopropyl alcohol (IPA)
2.Aqueous agent
•PINE ALPHA ST-100S
(4)There shall be no residual flux and residual cleaner after cleaning.
In the case of using aqueous agent, products shall be dried completely after rinse with de-ionized water
in order to remove the cleaner.
(5)Other cleaning
Please contact us.
10-10. 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
10-11.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.
• Products should be stored under the airtight packaged condition.
(3)Delivery
Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock.
