Classifications :
l SMB A-Series Chip Beads
The A-series is designed for general purpose
applications. This series covers a wide range of
impedance characteristics.
l SMB B-Series Chip Beads
The B-series is designed for high frequency
applications. This series minimizes attenuation
of the signal waveform due to its sharp
impedance characteristics
l SMB P-Series Chip Beads
The P-series is designed for high current
applications. These chips are suitable for filtering
noise near power lines and can match currents to
a maximum of 6A DC.
l SMB L-Series Chip Beads
The L-series is designed for high Current & low
DC resistance signal lines applications.
l SMB R-Series Chip Beads
The R-series is design for low Frequency
applications. These chips are able to generate
higher impedances at lower frequencies.
