SMD Inductors(Coils)
For Power Line(Wound, Magnetic Shielded)
Conformity to RoHS Directive
VLF Series VLF10040
FEATURES
• Mount area: 9.7× 10.0mm
Low profile: 4.0mm max. height
• Compare to SLF10145(TDK conventional product) type
Low loss and large current capability design
DC resistance: 0.92× SLF10145
Rated DC current: 1.3× SLF10145
• Generic use for portable DC to DC converter line
• High magnetic shield construction should actualize high resolu-
tion for EMC protection.
• Available for automatic mounting in tape and real package.
• The products do not contain lead and support lead-free solder-
ing.

∗ _{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.
