!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.
■ Notice (Storage and Operating Conditions)
< Operating Environment >
Do not use products in chemical atmosphere such as
chlorine gas, acid or sulfide gas.
< Storage Requirements >
1. Storage Period
LQG/LQM series should be used within 6 months; the
other products should be used within 12 months.
Solderability should be checked if this period is
exceeded.
2. Storage conditions
(1) Store products in a warehouse in compliance with
the following conditions :
Temperature : -10 to 40 degree C.
Humidity : 30 to 70% (relative humidity)
Do not subject products to rapid changes in
temperature and humidity.
Do not store them in chemical atmospheres such
as one containing sulfurous acid gas or
alkaline gas.
This will prevent electrode oxidation which
causes poor solderability and possible
corrosion of coils.
(2) Do not store products in bulk packaging to
prevent collision among coils 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.
■ Notice (Handling)
This item is designed to have sufficient strength,
but handle with care to avoid chipping or breaking
its ceramic structure.
LQW_A series
• To prevent breaking the wire, avoid touching sharp
material, such as tweezers, to the winding portion.
• To prevent breaking the core, avoid applying
excessive mechanical shock to products mounted on
the board.
• In some mounting machines, when picking up
components, support pin pushes up the components
from the bottom of base tape. In this case, please
remove the support pin. The support pin may damage
the components and break wire.
LQH_C/D/H/M/N, LQW_H series
• To prevent breaking the wire, avoid touching sharp
material, such as tweezers, to the winding portion.
• To prevent breaking the core, avoid applying
excessive mechanical shock to products mounted on
the board.
LQP series
• The pattern of the chip coil is covered with
protective film. Take care to avoid damaging the
chip coil when handling it with pick-up nozzles,
sharp instruments, etc.
LQM series
• There is the possibility that magnetism may change
the inductance value. Do not use a magnet or
tweezers with magnetism when handling chip coils.
(The tip of the tweezers should be molded with
resin or pottery.)
< Handling >
1. Avoid applying excessive stress to products to
prevent damage.
2. Do not touch winding with sharp objects such as
tweezers to prevent wire breakage.
3. Do not apply excessive force to products mounted
on boards to prevent core breakage.
< Transportations >
Do not apply excessive vibration or mechanical shock
to products.
< Resin Coating >
When coating products with resin, the relatively high
resin curing stress may change inductance values.
For exterior coating, select resin carefully so that
electrical and mechanical performance of the product
is not affected.
