ERROXCUBE is a member of the Yageo Group,
Fwhich
is among the world's strongest suppliers of high
quality passive components. As a leading supplier of
ferrite components, FERROXCUBE has manufacturing
operations, sales offices, and customer service centers
all over the world.
We supply one of the broadest ranges of highquality, innovative products and place strong emphasis
on miniaturization of magnetic functions. Ferrite
components and accessories from FERROXCUBE
are used in a wide range of applications, from
telecommunications and computing electronics
through consumer electronic products to automotive.
FERROXCUBE as the leading manufacturer in the
ferrite industry, has been providing to the power
conversion industry ferrite cores with low power
losses and high saturation magnetic flux density
over a wide range of operating frequencies (20KHz
to 10MHz). This has allowed us to support today’s
manufacturers of power conversion systems in their
drive for greater miniaturization, lower weight and
reduced power consumption in applications where
the temperature rise and maximum achievable
temperature can be estimated.
Energy loss in power conversion systems
is generated, among others, in the magnetic
components. Within the magnetics there are
losses in the windings (due to ohmic losses)
and on the ferrite core. Ferroxcube keeps
on working to improve the ferrite materials
used on them to offer solutions that enable
fulfilling the most stringent energy efficiency
standards, such as Energy Star or 80 Plus.

Low losses and high saturation flux have
lead 3C96 to be the preferred material
on applications demanding high efficiency.
Together with FXC 3C90 and 3C94 completes the low loss power conversion material family with
optimal working temperature at 100ºC.

Power loss comparison
FXC 3C98 is the new best in class medium
800
frequency power conversion material, making
handbook, halfpage
Pv
a break-through on the key parameters that
(kW/m 3 )
define the performance of power ferrites:
600
extremely low losses under high flux conditions
(250 mw/cm3 at 100 kHz, 200 mT) and high
saturation flux (530 mT). Being a material with
400
minimum loss at 100ºC, the loss curve has been
flattened, resulting in good performance at room
200
temperature.
These characteristics are more remarkable in
the frequency band below 200 kHz, though the
operating frequency spans up to 400 kHz.
