12. Precautions for Use
This product is for use only with reflow soldering. It is designed to be mounted by soldering. If you want to use other mounting
method, for example, using a conductive adhesive, please consult us beforehand.
12.1 Land dimensions
The following diagram shows the recommended land dimensions for reflow soldering.
The land dimensions are designed in consideration of electrical characteristics and mountability. Use of other land
dimensions may preclude achievement of performance. In some cases, it may result in poor solderability, including positional
shift. If you use other land pattern, consider it adequately.

12.2 Flux and solder used
Flux
• Use a rosin-based flux that includes an activator with a chlorine conversion value of 0.06(wt)% to 0.1(wt)%.
• Do not use a highly acidic flux with a halide content exceeding 0.2(wt)% (chlorine conversion value).
• Do not use a water-soluble flux.
Solder
• Use Sn-3.0Ag-0.5Cu solder.
• Standard thickness of solder paste: 80 μm to 100 μm
If you want to use a flux other than the above, please consult our technical department.
12.3 Soldering conditions (reflow)
• Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to 150°C
max.
Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 100°C max.
Insufficient pre-heating may cause cracks on the product, 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.

12.4 Reworking with soldering iron
Do not perform reworking with a soldering iron on this product.
12.5 Solder volume
Solder shall be used not to increase the volume too much.
An increased solder volume increases mechanical stress on the product. Exceeding solder volume may cause the failure of
mechanical or electrical performance.

12.6 Product's location
The following shall be considered when designing and laying out PCBs.
(1) PCB shall be designed so that products are not subject to mechanical stress due to warping the board.
[Products direction]
Products shall be located in the sideways direction (length: a < b) to the mechanical stress.
a
b
〈 Poor example〉
〈 Good example〉
(2) Components location on PCB 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.
12.7 Handling of 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.

12.8 Cleaning
The product shall be cleaned under the following conditions.
(1) The cleaning temperature shall be 60°C max. If isopropyl alcohol (IPA) is used, the cleaning temperature shall be 40°C
max.
(2) Perform ultrasonic cleaning under the following conditions. Exercise caution to prevent resonance phenomenon in
mounted products and the PCB.

(3) Cleaner
Alcohol-based cleaner: IPA
Aqueous agent: PINE ALPHA ST-100S
(4) There shall be no residual flux or residual cleaner. When using aqueous agent, rinse the product with deionized water
adequately and completely dry it so that no cleaner is left.
* For other cleaning, consult our technical department.
12.9 Storage and transportation
Storage period
Use the product within 12 months after delivery.
If you do not use the product for more than 12 months, check solderability before using it.
Storage conditions
• The products shall be stored in a room not subject to rapid changes in temperature and humidity.
The recommended temperature range is -10°C to +40°C. The recommended relative humidity
range is 15% to 85%.
Keeping the product in corrosive gases, such as sulfur, chlorine gas or acid, oxidizes the
electrode, resulting in poor solderability or corrosion of the coil wire of the product.
• Do not keep products in bulk packaging. Doing so may cause collision between the products or
between the products and other products, resulting in core chipping or wire breakage.
• Do not place the products directly on the floor; they should be placed on a palette so that they are
not affected by humidity or dust.
• Avoid keeping the products in a place exposed to direct sunlight, heat or vibration.
Transportation
Excessive vibration and impact reduces the reliability of the products. Exercise caution when
handling the products.
12.10 Resin coating
The inductance value may change due to high cure-stress of resin to be used for coating/molding products.
A wire breakage issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating
condition etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under some
operating condition may cause corrosion of wire of coil, leading to wire breakage.
So, please pay your careful attention when you select resin in case of coating/molding the products with the resin.
Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your
board.
12.11 Handling of product
• Sharp material such as a pair of tweezers or other material such as bristles of cleaning brush, shall not be touched to the
winding portion to prevent the breaking of wire.
• Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core.
12.12 Handling with mounting equipment
• With some types of mounting equipment, a support pin pushes up the product from the bottom of the base (paper) tape
when the product is sucked with the pick-up nozzle.
When using this type of equipment, detach the support pin to prevent the breaking of wire on the product.
• In some cases, the laser recognition function of the mounting equipment may not recognize this product correctly.
Please contact us when using laser recognition. (There is no problem with the permeation and reflection type.)

14. Appendix
Electrical performance: Measuring method for inductance/Q (Q measurement is applicable only when the Q value is included
in the rating table.)
Perform measurement using the method described below. (Perform correction for the error deriving from the measuring
terminal.)
(1) Residual elements and stray elements of the measuring terminal can be expressed by the F parameter for the 2-pole
terminal as shown in the figure below.
(2) The product's impedance value (Zx) and measured impedance value (Zm) can be expressed as shown below, by using
the respective current and voltage for input/output.
Zm=
V1
I1
Zx=
V2
I2
(3) Thus, the relationship between the product's impedance value (Zx) and measured impedance value (Zm) is as follows.
Zx=α
Zm-β
1-ZmΓ
Here,
α = D/A = 1
β = B/D = Zsm - (1 - Yom Zsm) Zss
Γ = C/A = Yom
Zsm: measured impedance of short chip
Zss: residual impedance of short chip (0.464 nH)
Yom: measured admittance when measuring terminal is open
(4) Calculate inductance Lx and Qx using the equations shown below.
Im (Zx)
Lx: inductance of chip coil
Lx=
2πf
Qx: Q of chip coil
Im (Zx)
Qx=
f: measuring frequency
Re (Zx)
