The GMLB Series is Mag.Layers’ line of high quality ferrite chip beads. Using
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.

Small Chip-Shaped Design
The chip-shaped design makes GMLB chip beads ideal for automatic mounting.
High Soldering Heat Resistance
High quality termination allows both flow and re-flow soldering methods to be
applied.
Sharp High Frequency Characteristics
The GMLB high frequency chip series has sharp impedance characteristics, which
make it suitable for high-speed signal lines.
