The dc bias is more complex. The dc bias will affect both the m'
and m"
cally the magnetic path length. Therefore Fair-Rite provides dc
bias information based on a dc H field in oersted for many of its
suppression components. For all EMI suppression beads and
round cable suppression cores listed in the catalog a calculated
H value (H=1.256/l
direct current is shown. This calculated value of H should be
modified if more turns are used or if the current is not 1 A. A 2 Amp
current will of course double the value listed for the part. Once the
true dc H field is calculated, graphs in Figures 16 through 20 will
provide the change in impedance information for the appropriate
material, frequency and true H value.
Dc bias curves are included in this catalog for wound and
assembled parts as well as for those components for which the
magnetic path length cannot be easily calculated. For instance,
refer to the product sections for beads on leads, pages 29-40 and
chip beads, pages 50-73 . For each individual component an
impedance vs. frequency curve with the dc bias as a parameter
is included. Again, this will provide the designer with a quick
evaluation on how the dc affects the performance of these
components.
Note: (914) Area Code has changed to (845).
