◆ FEATURES ◆ PRODUCT INDENTIFICATION
SMI-PDF/PEF chip inductors are 3L line of
high quality ferrite chip inductors. Using
the latest innovations in multilayer
technology, we have developed reliable
chip inductors that have high quality
characteristics.
High Performance Characteristics
SMI-PDF/PEF chips exhibit low DC
resistance and high current.
Wide Inductance Range
SMI-PDF/PEF chip inductors cover a wide
range of inductance values from 0.047 µH
to 22 µH.
High Reliability
SMI-PDF/PEF chip inductors have a
monolithic inor- ganic material construction
that effectively minimizes electromagnetic
interference.
High Soldering Heat Resistance
SMI-PDF/PEF chip inductors have high
quality termination allowing both flow and
reflow soldering methods to be used.
