Rating
Storage and Operating Condition
Handling
1. About the Rated Current
Do not use products beyond the rated current as this may
create excessive heat and deteriorate the insulation
resistance.
2. About Excessive Surge Current
Surge current (pulse current or rush current) greater than
the specified rated current applied to the product may
cause a critical failure, such as an open circuit or burnout
caused by excessive temperature rise.
Please contact us in advance if applying a surge current.
<Operating Environment>
Do not use products in a chemical atmosphere such as
chlorine gas, acid or sulfide gas.
<Storage Requirements>
1. Storage Period
The LQM series should be used within 6 months; the other
products should be used within 12 months.
Check solderability if this period is exceeded.
2. Storage Conditions
(1) Store products in a warehouse in compliance with the
following conditions:
Temperature: -10 to +40°C.
Humidity: 15 to 85% (relative humidity)
Do not subject products to rapid changes in
temperature and humidity.
Do not store them in a chemical atmosphere such as
one containing sulfurous acid gas or alkaline gas.
This will prevent electrode oxidation, which causes
poor solderability and possible corrosion of inductors.
(2) Do not store products in bulk packaging to prevent
collision among inductors, which causes core chipping
and wire breakage.
(3) Store products on pallets to protect from humidity,
dust, etc.
(4) Avoid heat shock, vibration, direct sunlight, etc.
This item is designed to have sucient strength, but handle
with care to avoid chipping or breaking its ceramic
structure.
LQW_C series
a To prevent breaking the wire, avoid touching with sharp
materials, such as tweezers or other materials such as
the bristles of a cleaning brush, to the wire wound
portion.
a To prevent breaking the core, avoid applying excessive
mechanical shock to products mounted on the board.
a In some mounting machines, when picking up
components, a support pin pushes the components up
from the bottom of the base tape. In this case, please
remove the support pin. The support pin may damage
the components and break the wire.
a In rare cases, the laser recognition cannot recognize this
component. Please contact us when you use laser
recognizion. (There is no problem with the permeation
and reflection type.)
a The product temperature rises about 40°C maximum
when the permissible current is applied to
LQW15C/LQW18C. Please use caution regarding the
temperature of the substrate and air around the part.
LQH_C/D/H/M/N/P series
a To prevent breaking the wire, avoid touching with sharp
materials, such as tweezers or the bristles of a cleaning
brush, to the wire wound portion of this product.
a To prevent breaking the core, avoid applying excessive
mechanical shock to products mounted on the board.
a Temperature may rise up to max. 40°C when applying
the rated current to Inductors for Power Lines. Use
caution regarding the temperature rating of the circuit
board and components around the chip Inductors.
LQM series
a There is the possibility that magnetism may change the
inductance value. Do not use a magnet or tweezers
with magnetism when handling chip inductors. (The tip
of the tweezers should be molded with resin or
pottery.)
a When the excessive current over rated current is
applied, it may cause the inductance value to change
due to magnetism.
<Transportation>
Do not apply excessive vibration or mechanical shock to
products.
