APPLICATION CIRCUIT
Bel has created a family of low profile, surface mount PC-card magnetics modules that are compatible with the
recommended application circuits from a variety of semiconductor manufacturers. In addition, Bel has created additional
versions that are suitable as an alternate source when choosing magnetics suppliers. Consult the Bel short form catalog
and recommended application circuit for the specific configuration of each Bel part type.
Each Bel module is designed with pre-emphasis and impedance matching resistors, filter networks for wave shaping,
isolation transformers and common mode chokes.
For more detailed information regarding the use and application of any device listed herein, including the timing and
availability of Type I height magnetic modules, please contact the nearest Bel office.
