FEATURES
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.
Multi-line EMI Suppression
M-series chip arrays contain four ferrite beads in a single package. This compact
design makes the M-series perfect for EMI suppression on multiple-lines.
High Density Packaging
M-series chip arrays have a compact package design that is an ideal for high density
packaging.
Multi-frequency Applications
M-series chip arrays are available in A-type and B-type. The A-type chip arrays are
designed for lower frequency applications. The B-type chip arrays are designed for
high frequency applications.
