NANOCRYSTALLINE/AMORPHOUS/DUST CHOKE COILS

Amorphous metal and NIPPON CHEMI-CON Amorphous Choke CoilThe 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 withconventional metallic substances.
NIPPON CHEMI-CON started developing amorphous components for electronic and electric equipment by making full use of thematerial and process technologies at its early stages and has continued the synthetic research and development to optimally match theamorphous 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 sophisticat
ed production technology and manufacturing know-how.

Incombustibility*1 Temperature on the coil surface including the temperature risein installation. Never use the coil at a temperature exceeding therated 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.
●The allowable tolerance of various rated inductance is as follows:
・AMORPHOUS CHOKE COILS：±25%
・DUST CHOKE COILS：±20％

Note carefully that the temperature of the core may exceed the operating temperature range depending on the circumference conditioneven if the coil is used in the speciﬁcation ranges described above.

◆Notes on use●The indicated heat-resistant temperatures are the guaranteed temperatures including coil self-generated heat.

●In high-temperature,-humidity environment, There is a possibility to occur hydrolyze and insulation deterioration.
●Common mode coils, by the unbalanced current, it may cause a magnetic saturation.
●We do not acquire safety standards with coil only.

●Ensure that you do not repeatedly apply excessive force to the lead wires or repeatedly bend them.
●Do not bang the coil against hard objects. Scratch on the coating, possibly impairing performance.
●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.
