Metal Multilayer Chip Power Inductors (MCOILTM MC series)
■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）
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.
◆Pattern configurations（Inductor layout on panelized［ breakaway］ PC boards）
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）
The following diagrams and tables show some examples of recommended patterns to prevent excessive solder amounts. Examples of
improper pattern designs are also shown.

i_mlci_MC_prec_e-E08R01
◆Pattern configurations（Inductor layout on panelized［ breakaway］ PC boards）
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
Recommended
Position the component at a
right angle to the direction of
the mechanical stresses that
are anticipated.
Deflection of the board
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.
E
D
Perforation
C
A
B
Slit
Magnitude of stress
A＞B＝C＞D＞E
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
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.
◆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:

considerations

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.

4. Soldering
Precautions
◆Reflow soldering
・ Please contact any of our offices for a reflow soldering, and refer to the recommended condition specified.
・ The product shall be used reflow soldering only.
・ Please do not add any stress to a product until it returns in normal temperature after reflow soldering.
◆Lead free soldering
・ When using products with lead free soldering, we request to use them after confirming adhesion, temperature of resistance to soldering
heat, soldering etc sufficiently.
Temperature［℃］
◆Reflow soldering
・ If products are used beyond the range of the recommended conditions, heat stresses may deform the products, and consequently
degrade the reliability of the products.

considerations
◆Cleaning conditions

◆Cleaning conditions
・ If washed by supersonic waves, the products might be broken.
6. Resin coating and mold
Precautions
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. Thermal expansion and thermal shrinkage characteristics of resins may lead to the deterioration of inductors’ performance.
3. When a resin hardening temperature is higher than inductor operating temperature, the stresses generated by the excessive heat may
lead to damage in inductors.
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
・Always wear static control bands to protect against ESD.
・ Keep the inductors away from all magnets and magnetic objects.
・ Use non-magnetic tweezers when handling inductors.
・ Any devices used with the inductors（ soldering irons, measuring instruments） should be properly grounded.
・ Keep bare hands and metal products（i.e., metal desk）away from inductor electrodes or conductive areas that lead to chip electrodes.
・ Keep inductors away from items that generate magnetic fields such as speakers or coils.
◆Mechanical considerations
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
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: 30℃ or below
Humidity: 70% RH or below
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
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.
