Features :
l High Performance Characteristics
SMI chips exhibit low DC resistance and high Q at
high frequency.
l Wide Inductance Range
SMI chip inductors cover a wide range of
inductance values from 0.047 µH to 220 µH.
l High Reliability
SMI chip inductors have a monolithic inor- ganic
material construction that effectively minimizes
electromagnetic interference.
l High Soldering Heat Resistance
SMI chip inductors have high quality termination
allowing both flow and reflow soldering methods
to be used.
