PRODUCT INDENTIFICATION
SMI –
SMI-P chip inductors are 3L line of high
current ferrite chip inductors. Minimized
design
that
is
suitable
for
portable
electronic equipments requiring low profile.
High Performance Characteristics
SMI-P chips exhibit low DC resistance and
high current.
Wide Inductance Range
SMI-P chip inductors cover a wide range of
inductance values from 1.0 µH to 10 µH.
High Reliability
SMI-P chip inductors have a monolithic
inor- ganic material construction that
effectively minimizes electromagnetic
interference.
High Soldering Heat Resistance
SMI-P chip inductors have high quality
termination allowing both flow and reflow
soldering methods to be used.
