6.Storage conditions
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.
Design
1.Please design insertion pitches of a base in the pitches that
fitted a terminal interval.
Wave soldering
1.Please refer to the specifications in the catalog for a wave
soldering.
2.Do not immerse the entire Inductors in the flux during the
soldering operation.
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, 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 product.
Cleaning conditions
1.TLF type
Please contact any of our offices for about a cleaning,
Handling
1.Keep the product away from all magnets and magnetic
objects.
Mechanical considerations
1.Please do not give the product any excessive mechanical
shocks.
2.TLF type
Please do not add any shock or and power to a product in
transportation.
Packing
1.Please do not give the product any excessive mechanical
shocks.
In loading, please pay attention to handling indication
mentioned in a packing box （a loading direction / number of
maximum loading / fragile item）.
Storage
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
 Ambient temperature      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.
1.When Inductors are mounted onto a PC board, hole dimensions on the board should
match the lead pitch of the component, if not, it will cause breakage of the terminals
or cracking of terminal roots covered with resin as excess stress travels through the
terminal legs.
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.
1.There is a case that a characteristic varies with magnetic influence.
1.There is a case to be damaged by a mechanical shock.
2.TLF type
There is a case to be broken by a fall.
1.There is a case that a lead route turns at by a fall or an excessive shock.
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.
