AMORPHOUS CHOKE COIL Characteristics
General specification can be Pb-free.
Contact NIPPON CHEMI-CON for details.
Notes on use
@Because
the insulating material of type B is used, the operating temperature of the coil should be less than 130C.
@Note
that the lead wire may not be subject to excess force and also may not be bent repeatedly because the wire is made of
copper.
@Never
make the coil hit on a hard and/or sharp substance. If so, the coating of the coils may be damaged to ruin the
performace of the coil.
@Contact
NIPPON CHEMI-CON for how to clean the substrate on which the coil is mounted.
@When
infra-acoustic frequency component is impressed, a beat sound some times occur.
Please ask for the individual catalog (NO. E1003), If you require the detailed specifications.

AMORPHOUS CHOKE COILS
Amorphous metal and NIPPON CHEMI-CON Amorphous Choke Coil
The amorphous metal has non cystalline structure generated by cooling molten metal rap-
idly. Due to the amorphous structure, the amorphous metal has excellent magnetic, me-
chanical, and chemical features in comparison with conventional metallic substances.
NIPPON CHEMI-CON started developing amorphous components for electronic and elec-
tric equipment by making full use of the metarial and process technologies at its early
stages and has continued the synthetic research and development to optimally match the
amorphous choke coils with the material features and their applications through a variety of
characteristics. NIPPON CHEMI-CON will help the customers design smaller and higher
performance products by supplying excellent amorphous choke coils through the sophisti-
cated production technology and manufacturing know-how.

at a temperature exceeding the rated temperature range.
*2 Recommended range. When infra-acoustic frequency component is impressed, a beat sound
some times occur.
*3 The temperature rise on the coil surface at the rated d.c. current.
*4 The incombustibility varies depending on the rated current. LCR meter, 10kHz.
*5 The housing case is made of FRPBT
Note carefully that the temperature of the core may exceed the operating temperature range de-
pending on the circumference condition even if the coil is used in the specification ranges de-
scribed above.
