10-2. Soldering Conditions
Products can be applied to reflow and flow soldering.
(1) Flux, Solder
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Flux
Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 μm
Solder
(2) Soldering conditions
• Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is
limited to 150°C max. Also cooling into solvent after soldering should be in such a way that the temperature
difference is limited to 100°C max.
Insufficient pre-heating may cause cracks on the ferrite, 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.

• Pre-heating: 150°C, 1 min
• Soldering iron output: 80W max.
• Tip diameter: φ3mm max.
• Times : 2times max.
• Tip temperature: 350°C max.
• Soldering time : 3(+1, -0) seconds.
Note : Do not directly touch the products with the tip of the soldering iron in order to prevent the crack on the
ferrite material due to the thermal shock.

10-6. 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.
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 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.
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.
