TEST EQUIPMENTS AND TEST SETUP
L&Q&SRF by Agilent E4991A RF Impedance
Analyzer with HP16197A Test Fixture.
DCR by milli-ohm meter.
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.
z High Performance Characteristics
SMI-P chips exhibit low DC resistance and
high current.
z Wide Inductance Range
SMI-P chip inductors co ver a wide range of
inductance values from 1.0 µH to 10 µH.
z High Reliability
SMI-P chip inductors have a monolithic
inor- ganic material construction that
effectively minimizes electromagnetic
interference.
z High Soldering Heat Resistance
SMI-P chip inductors have high quality
termination allowing both flow and reflow
soldering methods to be used.
APPLICATIONS
SMI chip inductors can be used in a
variety of electronics including:
z Mobile phones
z MP3 Player
z Bluetooth
z DSC
z LCD / DVR
z Portable digital
equipment
