10-2.Soldering Conditions
(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 150 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.
Standard Profile Limit Profile
Pre-heating 150180°C 90s±30s

Peak temperature 245±3°C 260°C,10s
Cycle of reflow 2 times 2 times
10-3. Reworking with soldering iron
Pre-heating: 150°C, 1 min Soldering iron output: 80W max.
Tip temperature: 350°C max. Tip diameter:φ3mm max.
Soldering time : 3(+1,-0) seconds. 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 exceeded as shown below.
1/3TtT
(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.
<Products direction>
Products shall be located in the sideways
direction (Length:a<b) to the mechanical
stress.
(2)Components location on P.C.B. separation.
It is effective to implement the following measures, to reduce stress in separating the board.
It is best to implement all of the following three measures; however, implement as many measures as possible
to reduce stress.
Contents of Measures Stress Level
(1) Turn the mounting direction of the component parallel to the board separation surface. A > D *1
(2) Add slits in the board separation part. A > B
(3) Keep the mounting position of the component away from the board separation surface. A > C
*1 A > D is valid when stress is added vertically to the perforation as with Hand Separation.
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.
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.

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.

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.
10-8. 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.
10-9. 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.
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.
