INDUCTANCE vs. DC SUPERPOSITION CHARACTERISTICS
VLS4012T-1R0N1R6
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
• All specifications are subject to change without notice.
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.
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
