10-2. Soldering Conditions
Products can be applied to reflow and flow soldering.
(1) Flux,Solder
Flux
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Solder
Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 μm
(2) Soldering conditions
• Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited
to 150℃ max. Also cooling into solvent after soldering should be in such a way that the temperature difference
is limited to 100℃ 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
• Tip temperature: 350°C max.
• Soldering time : 3(+1,-0) seconds.
• Soldering iron output: 80W max.
• Tip diameter:φ3mm max.
• Times : 2times max.
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.
10-4. Solder Volume
Solder shall be used not to be exceed as shown below.

(T:Chip thickness)
Accordingly increasing the solder volume, the mechanical stress to product is also increased.
Exceeding solder volume may cause the failure of mechanical or electrical performance.

10-5. Attention regarding P.C.B. bending
The following shall be considered when designing and laying out P.C.B.'s.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress for board warpage.

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.
Screw Hole
Recommended
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 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.

(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.
