components used in general purpose applications.
◆Operating Current（Verification of Rated current）
1. The operating current for inductors must always be lower than their rated values.
2. Do not apply current in excess of the rated value because the inductance may be reduced due to the magnetic saturation effect.
2. PCB Design
◆Pattern configuration（s Design of Land-patterns）
1. When inductors are mounted on a PCB, the size of land patterns and the amount of solder used（size of fillet）can directly affect inductor performance.
Therefore, the following items must be carefully considered in the design of solder land patterns:
（1）The amount of solder applied can affect the ability of chips to withstand mechanical stresses which may lead to breaking or cracking. Therefore, when
designing land-patterns it is necessary to consider the appropriate size and configuration of the solder pads which in turn determines the amount of
solder necessary to form the fillets.
（2）When more than one part is jointly soldered onto the same land or pad, the pad must be designed so that each component's soldering point is separated
Precautions
by solder-resist.
（3）The larger size of land patterns and amount of solder, the smaller Q value after mounting on PCB. It makes higher the Q value to design land patterns
smaller than terminal electrode of chips.
◆Pattern configuration（s Inductor layout on panelized［breakaway］PC boards）
1. After inductors have been mounted on the boards, chips can be subjected to mechanical stresses in subsequent manufacturing processes（PCB cutting,
board inspection, mounting of additional parts, assembly into the chassis, wave soldering the reflow soldered boards etc.）For this reason, planning pattern
configurations and the position of SMD inductors should be carefully performed to minimize stress.
◆Pattern configuration（s Design of Land-patterns）
1. The following diagrams and tables show some examples of recommended patterns to prevent excessive solder amount（s larger fillets which extend above
the component end terminations）. Examples of improper pattern designs are also shown.

Precautions on the use of Multilayer chip Inductors, Multilayer chip inductors for high frequency, Multilayer chip bead Inductors
2. PCB Design
◆Pattern configuration（s Inductor layout on panelized［breakaway］PC boards）
1-1. The following are examples of good and bad inductor layout; SMD inductors should be located to minimize any possible mechanical stresses from board
warp or deflection.
Item
Not recommended

Deflection of the board
1-2. To layout the inductors for the breakaway PC board, it should be noted that the amount of mechanical stresses given will vary depending on inductor layout.
An example below should be counted for better design.
Technical
consider-
ations
1-3. When breaking PC boards along their perforations, the amount of mechanical stress on the inductors can vary according to the method used. The following
methods are listed in order from least stressful to most stressful: push-back, slit, V-grooving, and perforation. Thus, any ideal SMD inductor layout must
also consider the PCB splitting procedure.
3. Considerations for automatic placement
◆Adjustment of mounting machine
1. Excessive impact load should not be imposed on the inductors when mounting onto the PC boards.
2. The maintenance and inspection of the mounter should be conducted periodically.
Precautions ◆Selection of Adhesives
1. Mounting inductors with adhesives in preliminary assembly, before the soldering stage, may lead to degraded inductor characteristics unless the following
factors are appropriately checked; the size of land patterns, type of adhesive, amount applied, hardening temperature and hardening period. Therefore, it is
imperative to consult the manufacturer of the adhesives on proper usage and amounts of adhesive to use.
◆Adjustment of mounting machine
1. If the lower limit of the pick-up nozzle is low, too much force may be imposed on the inductors, causing damage. To avoid this, the following points should be
considered before lowering the pick-up nozzle:
（1）The lower limit of the pick-up nozzle should be adjusted to the surface level of the PC board after correcting for deflection of the board.
（2）The pick-up pressure should be adjusted between 1 and 3N static loads.
（3）To reduce the amount of deflection of the board caused by impact of the pick-up nozzle, supporting pins or back-up pins should be used under the PC
board. The following diagrams show some typical examples of good pick-up nozzle placement:
Item
Improper method
Proper method
Single-sided mounting
Double-sided mounting
2. As the alignment pin wears out, adjustment of the nozzle height can cause chipping or cracking of the inductors because of mechanical impact on the
inductors. To avoid this, the monitoring of the width between the alignment pin in the stopped position, and maintenance, inspection and replacement of the
pin should be conducted periodically.
Technical
consider-
ations
◆Selection of Adhesives
1. Some adhesives may cause reduced insulation resistance. The difference between the shrinkage percentage of the adhesive and that of the inductors may
result in stresses on the inductors and lead to cracking. Moreover, too little or too much adhesive applied to the board may adversely affect component
placement, so the following precautions should be noted in the application of adhesives.
（1）Required adhesive characteristics
a. The adhesive should be strong enough to hold parts on the board during the mounting & solder process.
b. The adhesive should have sufficient strength at high temperatures.
c. The adhesive should have good coating and thickness consistency.
d. The adhesive should be used during its prescribed shelf life.
e. The adhesive should harden rapidly.
f. The adhesive must not be contaminated.
g. The adhesive should have excellent insulation characteristics.
h. The adhesive should not be toxic and have no emission of toxic gasses.
（2）When using adhesives to mount inductors on a PCB, inappropriate amounts of adhesive on the board may adversely affect component placement. Too
little adhesive may cause the inductors to fall off the board during the solder process. Too much adhesive may cause defective soldering due excessive
flow of adhesive on to the land or solder pad.

Precautions on the use of Multilayer chip Inductors, Multilayer chip inductors for high frequency, Multilayer chip bead Inductors
4. Soldering
◆Selection of Flux
1. Since flux may have a significant effect on the performance of inductors, it is necessary to verify the following conditions prior to use;
（1）Flux used should be with less than or equal to 0.1 wt%（Chlorine conversion method）of halogenated content. Flux having a strong acidity content should
not be applied.
Precautions
（2）When soldering inductors on the board, the amount of flux applied should be controlled at the optimum level.
（3）When using water-soluble flux, special care should be taken to properly clean the boards.
◆Soldering
1. Temperature, time, amount of solder, etc. are specified in accordance with the following recommended conditions, and please contact us about peak tem-
perature when you use lead-free paste.
◆Selection of Flux
1-1. When too much halogenated substance（Chlorine, etc.）content is used to activate the flux, or highly acidic flux is used, an excessive amount of residue
after soldering may lead to corrosion of the terminal electrodes or degradation of insulation resistance on the surface of the Inductor.
1-2. Flux is used to increase solderability in flow soldering, but if too much is applied, a large amount of flux gas may be emitted and may detrimentally affect
solderability. To minimize the amount of flux applied, it is recommended to use a flux-bubbling system.
1-3. Since the residue of water-soluble flux is easily dissolved by water content in the air, the residue on the surface of Inductor in high humidity conditions may
cause a degradation of insulation resistance and therefore affect the reliability of the components. The cleaning methods and the capability of the machines
used should also be considered carefully when selecting water-soluble flux.
◆Soldering
1-1. Preheating when soldering
Heating: Chip inductor components should be preheated to within 100 to 130℃ of the soldering. Cooling: The temperature difference between the
components and cleaning process should not be greater than 100℃.
Chip inductors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling. Therefore, the soldering process must be
conducted with a great care so as to prevent malfunction of the components due to excessive thermal shock.

5. Cleaning
◆Cleaning conditions
1. When cleaning the PC board after the Inductors are all mounted, select the appropriate cleaning solution according to the type of flux used and purpose of
the cleaning（e.g. to remove soldering flux or other materials from the production process.）
2. Cleaning conditions should be determined after verifying, through a test run, that the cleaning process does not affect the inductor's characteristics.
Precautions
◆Cleaning conditions
1. The use of inappropriate solutions can cause foreign substances such as flux residue to adhere to the inductor, resulting in a degradation of the inductor's
electrical propertie（s especially insulation resistance）.
2. Inappropriate cleaning condition（s insufficient or excessive cleaning）may detrimentally affect the performance of the inductors.
Technical
consider-
ations
（1）Excessive cleaning
a. In the case of ultrasonic cleaning, too much power output can cause excessive vibration of the PC board which may lead to the cracking of the inductor
or the soldered portion, or decrease the terminal electrodes' strength. Thus the following conditions should be carefully checked;
Ultrasonic output
Ultrasonic frequency
Ultrasonic washing period
Below 20W/ℓ
Below 40kHz
5 min. or less
6. Post cleaning processes
◆Application of resin coatings, moldings, etc. to the PCB and components.
1. With some type of resins a decomposition gas or chemical reaction vapor may remain inside the resin during the hardening period or while left under normal
storage conditions resulting in the deterioration of the inductor's performance.
2. When a resin's hardening temperature is higher than the inductor's operating temperature, the stresses generated by the excess heat may lead to inductor
damage or destruction.
3. Stress caused by a resin's temperature generated expansion and contraction may damage inductors.
Precautions
7. Handling
The use of such resins, molding materials etc. is not recommended.
◆Breakaway PC board（s splitting along perforations）
1. When splitting the PC board after mounting inductors and other components, care is required so as not to give any stresses of deflection or twisting to the
board.
2. Board separation should not be done manually, but by using the appropriate devices.
◆General handling precautions
1. Always wear static control bands to protect against ESD.
2. Keep the inductors away from all magnets and magnetic objects.
Precautions
3. Use non-magnetic tweezers when handling inductors.
4. Any devices used with the inductors（soldering irons, measuring instruments）should be properly grounded.
5. Keep bare hands and metal product（s i.e., metal desk）away from chip electrodes or conductive areas that lead to chip electrodes.
6. Keep inductors away from items that generate magnetic fields such as speakers or coils.
◆Mechanical considerations
1. Be careful not to subject the inductors to excessive mechanical shocks.
（1）If inductors are dropped on the floor or a hard surface they should not be used.
（2）When handling the mounted boards, be careful that the mounted components do not come in contact with or bump against other boards or components.
8. Storage conditions
◆Storage
1. To maintain the solderability of terminal electrodes and to keep the packaging material in good condition, care must be taken to control temperature and
humidity in the storage area. Humidity should especially be kept as low as possible.
Recommended conditions
Ambient temperature Below 40℃
Precautions
Humidity
Below 70% RH
The ambient temperature must be kept below 30℃. Even under ideal storage conditions inductor electrode solderability decreases as time passes, so
inductors should be used within 6 months from the time of delivery.
*The packaging material should be kept where no chlorine or sulfur exists in the air.
◆Storage
Technical
consider-
ations
1. If the parts are stocked in a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes
and deterioration of taping/packaging materials may take place. For this reason, components should be used within 6 months from the time of delivery. If
exceeding the above period, please check solderability before using the inductors.
