∗ Handling power=(Inductance value)× (Current)2. It is possible to design within the range below this value.
[Example] The coil for 2A can make even the inductance of 2.5mH or less a product for handling power 10.
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• All specifications are subject to change without notice.
