(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
•
Soldering iron output: 80W max.
•
Tip diameter:

3mm 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.

(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.

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 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.
