This information is
intended to be used in
assisting the designer in
part selection. Each
application may contain
other variables which
must be considered in
part selection, such as
temperature effects,
waveform distortion, etc.
API Delevan
Sales/Engineering is
available to provide
information as needed to
fit each application.
Data is representative of
a DC current with less
than 1% ripple and an
AC waveform less than:
50 gauss on the
HCT-37X, 25 gauss on
the HCT-44X, 15 gauss
on the HCT-50X and 10
gauss on the
HCT-68X.The effect of
AC or ripple flux can be
significant in many DC
inductor applications.
When significantly
greater AC flux density is
present, it becomes
necessary to consider its
effect on both core loss
and permeability
(inductance).
All data points, on the
above graphs, that
exceed the rated DC
current specified for a
55°C rise from a 25°C
ambient are for design
reference only and are
not intended to imply
continuous use at those
DC current levels.
