The GMLB Series is Mag.Layers’ line of high quality ferrite chip beads. Using
the latest in multilayer technology, we have developed chip beads that are able
to resolve all EMI/EMC issues. High quality, reliability, and versatility make the
GMLB series chip beads suitable for all your design needs.
z High Reliability
The monolithic inorganic materials used to construct GMLB chips restrain magnetic
flux leakage thereby minimizing EMI concerns. GMLB chips are also extremely
effective with unstable grounding.
z Small Chip-Shaped Design
The chip-shaped design makes GMLB chip beads ideal for automatic mounting.
z High Soldering Heat Resistance
High quality termination allows both flow and re-flow soldering methods to be
applied.
z Sharp High Frequency Characteristics
The GMLB high frequency chip series has sharp impedance characteristics, which
make it suitable for high-speed signal lines.
