SMD Inductors(Coils)
For Signal Line(Multilayer, Magnetic Shielded)
MLF Series MLF2012-J
Since digital devises have become faster and have more functions,
stricter inductance tolerance has become necessary in the high
frequency range.
The ferrite material and internal electrodes for MLF2012-J toler-
ance products have been newly developed and have received opti-
mal process design. As a result, tolerance could be narrowed
(±5%) to half of the previous MLF series, and drift variance was
also been greatly improved.
FEATURES
• Inductance tolerance is ±5% (J-tolerance)
• Temperature stress (drift variance percentage) for soldering is
• The products contain no lead and also support lead-free
• It is a product conforming to RoHS directive.
APPLICATIONS
Signal processing such as car audio, automotive (intended) use,
tuner.
