No polarity.
Operating Temperature Range (Ambient Temperature Range + Winding Temperature Rise): -25
°C to 120°C
Winding Temperature Rise (at Rated Current) (max.): 60K
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.
*As for FKOB series winding temperature should be
less than 95 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 assembled 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.
I !Caution (Rating)
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.
I Notice (Soldering and Mounting)
Coil Humming Noise
Magnetic flux generated between coil and core or
between the choke coil windings creates repulsive
power between the coil windings. This repulsive
power causes the coil winding to vibrate and create
a humming noise. The amount of hum produced by the
coil is proportionate to the amount of harmonic
distortion generated by the operating current. This
does not influence the electrical performance of
the coils, but it should be considered and tested
in actual circuit application.
