Technical considerations
1.Circuit Design
Operating environment,
1.The products described in this specification are intended for
use in general electronic equipment,(office supply
equipment, telecommunications systems, measuring
equipment, and household equipment). They are not
intended for use in mission-critical equipment or systems
requiring special quality and high reliability (traffic systems,
safety equipment, aerospace systems, nuclear control
systems and medical equipment including life-support
systems,) where product failure might result in loss of life,
injury or damage. For such uses, contact TAIYO YUDEN
Sales Department in advance.

2.PCB Design
Land pattern design
1.Please contact any of our offices for a land pattern, and refer
to a recommended land pattern of specifications.
Adjustment of mounting machine
3.Considerations for
automatic placement
1.Excessive impact load should not be imposed on the
products when mounting onto the PC boards.
2.Mounting and soldering conditions should be checked
beforehand.
1. When installing products, care should be taken not to apply distortion stress as it may
deform the products.
4.Soldering
Reflow soldering
1.Please contact any of our offices for a reflow soldering, and
refer to the recommended condition specified.
2.This products is reflow soldering only.
1.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.
3.SMD Inductors
Please do not add any stress to a product until it returns in
normal temperature after reflow soldering.
Lead free soldering
1.When using products with lead free soldering, we request to
use them after confirming of adhesion, temperature of
resistance to soldering heat, soldering etc sufficiently.
Recommended conditions for using a soldering iron:
Put the soldering iron on the land-pattern.
Soldering iron's temperature - Below 350 ℃
Duration - 3 seconds or less
The soldering iron should not directly touch the inductor.

6.Handling
1.SMD Inductors
Please contact any of our offices for a cleaning,
Handling
1.Keep the product away from all magnets and magnetic
objects.
1.There is a case that a characteristic varies with magnetic influence.
Breakaway PC boards (splitting along perforations)
1.When splitting the PC board after mounting product, care
should be taken not to give any stresses of deflection or
twisting to the board.
1.Planning pattern configurations and the position of products should be carefully
performed to minimize stress.
2.Board separation should not be done manually, but by using
the appropriate devices.
Mechanical considerations
1.Please do not give the product any excessive mechanical
shocks.
1.There is a case to be damaged by a mechanical shock.

Please do not push to add any pressure to a winding part.
Damage and a characteristic can vary with an excessive shock or stress.
Please do not give any shock and push into a ferrite core
exposure part.
Packing
1.SMD Inductors
Please avoid accumulation of
a
packing box as much as
1.There is
a case that transformation and a product of tape are damaged by
possible.
Storage
accumulation of a packing box.
7.Storage conditions
1.To maintain the solderability of terminal electrodes and to
keep the packing material in good condition, temperature
and humidity in the storage area should be controlled..
・Recommended conditions
1. Under
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.
ꢀAmbient temperatureꢀꢀꢀꢀꢀ 0～40℃
ꢀHumidity
ꢀBelow 70% RH
The ambient temperature must be kept below 30℃. Even
under ideal storage conditions, solderability of products
electrodes may decrease as time passes. For this reason,
product should be used within one year from the time of
delivery.
In case of storage over
6 months, solderability shall be
checked before actual usage.
