automatic placement
4.Soldering
5.Cleaning
6.Handling
7.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.
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
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.
Wave soldering
1.Please refer to the specifications in the catalog for a wave
soldering.
Reflow soldering
1.Please contact any of our offices for a reflow soldering, and
refer to the recommended condition specified.
2.LER012 Type,LB Type
Reflow solderring only.
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 inductor.
Cleaning conditions
LB Type
1.Washing by supersonic waves shall be avoided.
Handling
1.Keep the inductors away from all magnets and magnetic
objects.
Breakaway PC boards (splitting along perforations)
1.When splitting the PC board after mounting inductors, care
should be taken 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.
Mechanical considerations
1.Please do not give the inductors any excessive mechanical
shocks.
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, LE type inductors
should be used within one year from the time of delivery.
LER type, LB type
Please should be used within 6 months from the time of delivery.
LE type
In case of storage over 6 months, solderability shall be
checked before actual usage.
1. When installing products, care should be taken not to apply distortion stress as it may
deform the products.
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.
LB Type
1.If washing by supersonic waves, supersonic waves may cause broken products.
1.There is a case that a characteristic varies with magnetic influence.
1.Planning pattern configurations and the position of products should be carefully
performed to minimize stress.
1.There is a case to be damaged by a mechanical 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.
