Precautions on the use of Multilayer chip inductors
Multilayer chip inductors for high frequency, Multilayer chip bead inductors
Multilayer common mode choke coils（MC series F type）
■PRECAUTIONS
1. Circuit Design
Precautions
◆Verification of operating environment, electrical rating and performance
1. A malfunction in medical equipment, spacecraft, nuclear reactors, etc. may cause serious harm to human life or have severe social
ramifications.
As such, any inductors to be used in such equipment may require higher safety and/or reliability considerations and should be clearly
differentiated from components used in general purpose applications.
◆Operating Current（Verification of Rated current）
1. The operating current including inrush 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
Precautions
◆Pattern configurations（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 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 configurations（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 configurations（Design of Land-patterns）
1. The following diagrams and tables show some examples of recommended patterns to prevent excessive solder amounts（larger fillets
which extend above the component end terminations）. Examples of improper pattern designs are also shown.

3. Considerations for automatic placement
Precautions
◆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.
◆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:

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.
◆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.

4. Soldering
Precautions
◆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.
（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 temperature when you use lead-free paste.
▶ This catalog contains the typical specification only due to the limitation of space. When you consider the purchase of our products, please check our specification.
For details of each product (characteristics graph, reliability information, precautions for use, and so on), see our Web site (http://www.ty-top.com/) .
i_mlci_prec_e-E07R01
◆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.

i_mlci_prec_e-E07R01
Caution
1. Use a 20W soldering iron with a maximum tip diameter of 1.0 mm.
2. The soldering iron should not directly touch the inductor.
5. Cleaning
Precautions
◆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.
Technical
considerations
◆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 properties（especially insulation resistance）.
2. Inappropriate cleaning conditions（insufficient or excessive cleaning）may detrimentally affect the performance of the inductors.
（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
Below 20W/ℓ
Ultrasonic frequency
Below 40kHz
Ultrasonic washing period
5 min. or less
6. Post cleaning processes
Precautions
◆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.
The use of such resins, molding materials etc. is not recommended.
7. Handling
Precautions
◆Breakaway PC boards（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.
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 products（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
Precautions
◆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 30℃
Humidity: Below 70% RH
The ambient temperature must be kept below 40℃. Even under ideal storage conditions, solderability of inductor is deteriorated as time
passes, so inductors should be used within 6 months from the time of delivery.
・Inductor should be kept where no chlorine or sulfur exists in the air.
Technical
considerations
◆Storage
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.
