nanocrystalline VITROPERM 500F
Toroidal Cores for Common Mode Chokes
and EMC applications
For noise attenuation in applications like SMPS, welding units or inverters, tape-wound cores made of nanocrystalline
VITROPERM 500 F offer significant advantages in volume and performance. The benefits come from the unique combination
of material properties, like high initial permeabiltiy, high permeability levels (µ » 30 000 and 80 000) over a wide frequency
range combined with high saturation flux density and low core losses. For a common mode choke the following advantages can
be achieved:
· high inductance at a low coupling capacity and low DC - losses.
· high insertion attenuation over a wide frequency range.
· smallest size.

nanocrystalline VITROPERM 500 F
Toroidal Cores for Common Mode Chokes
and EMC applications
VF - Series
„VF“ is our synonym for a new series of volume-optimized and frequency-improved cores for Common-Mode
Chokes and all other kind of EMC applications. They are designated to meet the steadily increasing requirements of
the EMC market:
· The latest improvements of our innovative nanocrystalline core material VITROPERM 500 F assure excellent
high - frequency attenuation and low losses. In addition to the conventional 10 kHz – measurement, the AL –
value of the VF - cores is specified and tested at f = 100 kHz.
· All cores offer a particular large inner diameter allowing high numbers of turns to achieve a high inductance and
a high current - handling capability at the same time. Superb damping results can be achieved by using a low -
capacitive geometry of the windings. All listed core items are finished with epoxy coating (Fix 350, Fix 351).
· VF - cores are available with a medium permeability of 30 000, depending on the core size additionally also with
permeability levels of 18 000 or over 50 000 .
· Our highly automatized manufacturing process enables an attractive pricing for the VF - series.
