AMORPHOUS / DUST CHOKE COILS
Amorphous metal and NIPPON CHEMI-CON Amorphous Choke Coil
The amorphous metal has non crystalline structure generated by cooling molten metal
rapidly. Due to the amorphous structure, the amorphous metal has excellent magnetic,
mechanical, and chemical features in comparison with conventional metallic substances.
NIPPON CHEMI-CON started developing amorphous components for electronic and
electric equipment by making full use of the material 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 vari-
ety of characteristics. NIPPON CHEMI-CON will help the customers design smaller and
higher performance products by supplying excellent amorphous choke coils through the
sophisticated production technology and manufacturing know-how.

*1 Temperature on the coil surface including the temperature rise
in installation. Never use the coil at a temperature exceeding the
rated temperature range.
*2 Recommended range. When infra-acoustic frequency component
is impressed, a beat sound sometimes occurs.
*3 The temperature rise on the coil surface at the rated d.c. current.
Note carefully that the temperature of the core may exceed the operating temperature range
depending on the circumference condition even if the coil is used in the specification ranges
described above.

◆Notes
on use
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 perfor-
mance 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 sometimes occurs.

Regarding compliance for EU REACH Regulation
(1) According to the content of REACH handbook (Guidance on requirements for substances in articles which is published on
May 2008), our electronic components are "articles without any intended release". Therefore they are not applicable for
"Registration" for EU REACH Regulation Article 7 (1).
Reference: Electrolytic Condenser Investigation Society
"Study of REACH Regulation in EU about Electrolytic Capacitor" (publicized on 13 March 2008)
(2) Nippon Chemi-Con develops the products without substance of very high concern(SVHC).DEHP(CASNo.117-81-7) was
contained as some covering material, Nippon Chemi-Con abolished use of DEHP totally at June, 2011.
