Rated current: Value obtained when current flows and the temperature has risen to 40°C or when DC current flows and the nominal value of inductance  
has fallen by 30%, whichever is smaller.  
• Operating temperature range: –40 to +105°C (Including self-temperature rise)  
• 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.
