!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.
■ !Caution (Rating)
1. Rated Current
Operating current should not exceed the rated value.
Even if operating current is under the rated value,
adequate ventilation is required to avoid excessive
heat generated within the product (choke coil) and
from surrounding heat sources.
If exceeding these conditions, excessive heat may
cause fumes or permanent damage to the product.
Please ensure that product (choke coil) is evaluated
and confirmed against the specification when it is
mounted in your final assembled product. -> Winding
temperature should be less than 120 degree C.
Maximum allowable temperature at the surface of coil
(ambient temperature + winding temperature rise) is
in accordance with each safety standard applicable
to final assembeld product.
When the temperature at winding exceeds maximum
allowable temperature of safety standard, the rated
current should be derated.
2. Inrush Current
Inrush current should not exceed 10 times rated
current within 1/4 cycle of 50/60Hz commercial
power line. Inrush current should be limited to a
minimum of 10 seconds after last inrush.
If these conditions are exceeded, excessive heat
may cause fumes or permanent damage to the
component, or at worst cause ignition.
■ Notice (Storage and Operating Condition)
1. Soldering Conditions
(1) Flux, solder
Rosin-based flux should be used.
Do not use strong acidic flux with halide
content exceeding 0.2%wt
(chlorine conversion value)
Use 63/37 solder (Sn 63%/Pb 37%) or 60/40
solder (Sn 60%/Pb 40%)
(2) Flow soldering
Products should be soldered by flow method
under the following conditions:
Soldering Temp. : 240 to 260 degree C
Soldering Time : Less than 5 s
2. Cleaning
Avoid cleaning product due to non-waterproof
construction.
3. Storage and handling requirements
(1) Storage period
Product should be used within 12 months after
receiving.
Solderability should be checked if this period
is exceeded.
(2) Storage conditions
Storage temperature : -10 to 40 degree C
Relative humidity : 30 to 70%
Avoid sudden changes in temperature and humidity.
Don't keep products in corrosive gases such as
sulfur, chlorine gas or acid, or it may cause
oxidation of lead terminals resulting in poor
solderability or corrosion of component windings.
(3) Handling conditions
Care should be taken when transporting or
handling product to avoid excessive vibration or
mechanical shock.
■ Notice (Soldering and Mounting)
Magnetic Flux Leakage
Choke coils generate small amounts of magnetic flux
leakage that may adversely affect equipment operation
according to component arrangement.
Testing should be completed on final assembly to
ensure equipment performance is not affected.
