VITROPERM nanocrystalline alloys are optimized to
combine highest permeability and lowest coercive
field strength. The combination of very thin tapes and
the relatively high electrical resistance (1.1 – 1.2
μΩm) ensure minimal eddy current losses and an
outstanding frequency vs. permeability behaviour.
Along with saturation flux density of 1.2 T and wide
operational temperature range, these features com-
bine to make VITROPERM a universal solution for
most common EMC problems and vastly superior in
many aspects to commonly used ferrite and amor-
phous iron materials.

VACUUMSCHMELZE has extensive practical and theo-
retical expertise in the design of CMCs and filter confi-
guration using nanocrystalline cores and components.
At higher frequencies, the winding configuration has a
major effect on the parameters of winding capacitance
and leakage inductance and is therefore carefully con-
sidered in our choke designs. Figure 4 shows a compa-
rison of insertion loss for two chokes which differ only
in their winding configuration (core material, number of
turns and wire thickness are identical in both cases).
This illustrates how our design expertise can improve
filter efficiency, maximize reliability and reduce costs.

The properties of VITROPERM are very much diffe-
rent from conventional ferrites. This has to be consi-
dered in the filter design for optimal solutions. The
main physical and magnetic characteristics are illus-
trated in the following diagrams.

VITROPERM 500F
The permeability of VITROPERM 500F is signifi-
cantly higher than ferrite in the low frequency range.
At higher frequencies the μ of both nanocrystalline
materials remains above that of ferrites. A high
choke impedance is preferred for a high attenuation.
This can be achieved more effectively by using high
permeability core materials than by increasing the
number of turns, as a lower number of turns results
in lower winding capacitance and hence improved
HF properties.

VITROPERM 500F, !=100 000
The frequency dependence of the permeability, μ(f)
of VITROPERM 500F and ferrites differ fundamen-
tally. μ(f) of μ=5 000 ferrites offer a flat and linear
characteristic up to approximately 1 MHz (ferrites
with μ=10 000 range up to approximately 200 kHz).
In this flat range, the attenuation properties are de-
termined by μ’ and the impedance |Z| is dominated
by the inductance L. If the self resonance of the
choke is within this frequency range, the attenuation
curve is narrow-band and attenuation is primarily
caused by reflection of the interference signal.
Above 1 MHz (or 200 kHz) Re(Z) takes the major
share of attenuation and μ’’ becomes the dominant
factor. If the self resonance of the choke is in this fre-
quency range the attenuation characteristic beco-
mes increasingly broadband.

VITROPERM is basically similar in this respect. The
flat sector of μ(f) of VITROPERM 500F ranges (de-
pending on the initial permeability level) to frequen-
cies of several 10 kHz (20 kHz in this example), only.
Consequently, attenuation (or |Z|) is already domi-
nated by Re(Z) and is always broadband in the
whole EMC-relevant range above 150 kHz. In-
ductance plays a minor role and describes the atte-
nuation only partially. The determining factor is the
total impedance. The approximation |Z|=ωL is valid
for ferrite chokes. For VITROPERM chokes |Z|>>ωL
applies. Attenuation primarily does not result from a
reflection of the interference signal, but from its ab-
sorption.

It is only when these different characteristics are
taken into consideration that the design of optimized,
compact and low-cost nanocrystalline chokes is pos-
sible. However, VITROPERM 250F is an exception,
because the flat μ(f) sector range is similar to
μ=5 000 ferrites to frequencies of up to 1 MHz and
the attenuation is primarily inductive.

The saturation flux density of VITROPERM changes
by only a few percent in the operating temperature
range of up to 150 °C, while MnZn ferrites decline
up to 40 % at temperatures above 100 °C. The high
Curie temperature of VITROPERM alloys (above
600 °C), allows short term maximum operating tem-
peratures as high as 180 – 200 °C 1).

The saturation behaviour of ferrite is less sensitive due to
itslowerpermeability.Forapplicationswithhigherimbalance
currents, the advantages of VITROPERM with 1.2Tsatu-
ration flux density (approximately 3 times higher than ferri-
tes) can still be realised since VITROPERM is available in

In these cases, a lower μ level may have to be selected in
order to find the optimum saturation-resistant solution. Fig.

with VITROPERM
The superior material properties of nanocrystalline
VITROPERM enable common mode chokes with
high inductance/impedance with a small number of
turns, resulting in reduced copper losses, low win-
ding capacitance and excellent HF performance.
Due to the high initial permeability, low winding ca-
pacitance and a low Q-factor (above 100 kHz)
VITROPERM CMCs offer a broadband insertion loss
curve ranging from 10 kHz up to several MHz and
improved attenuation behaviour at both low and high
frequencies in comparison to conventional ferrite
chokes with similar core dimensions and identical
windings (see Fig. 13).
Better attenuation properties and an extended ope-
rating temperature range allow a reduction of the
component volume by a factor of up to 3 or more
under similar conditions. Note that the insertion loss
curve of the small VITROPERM choke in Fig. 14 is
similar to that of ferrite materials at frequencies of
about 600 kHz – 1 MHz and is superior below 500
kHz and above 1 MHz.

Although the epoxy resin coating is suitable for direct winding, we recommend additional insula-
tion between core and winding for enhanced insulation requirements. The epoxy resin is suitable
for continuous operational temperatures of up to 120 °C and complies with the UL94-V0 standard
(UL file number: E214934), class A (105 °C).

The plastic cases are suitable for direct winding and offer good mechanical
protection of the nanocrystalline core material. This enables the best mag-
netic properties and highest permeability levels to be maintained. Additional
winding protection is optional for heavy wire windings, where there may be
a danger of core damage. The plastic materials comply with the standards
UL94-V0 (UL file number: E41871), class B (130 °C) and UL94-V0 (UL file
number E41938), class F (155 °C).

Single-turn chokes employing a number of nanocry-
stalline cores assembled in a stack are an effective
solution for bearing current problems or extremely
high common mode noise from other causes in
large-scale variable speed drives, wind generators
and other applications in which resonance pheno-
mena cause high-amplitude interference currents
(with peak values ranging from several 10 A to over
100 A). These generally take the form of short and
thus high-frequency current peaks. For these appli-
cations, VAC offers assembled core stacks which
can be easily and securely integrated into existing
applications with the minimum of effort.

The core stacks are available in two sizes with two
different through-hole diameters. They are custom-
designed, allowing an individual selection of core
type and the number of stacked cores (up to 7 pie-
ces) depending on the required saturation level and
the required inductance.

Generꢁꢂ informꢁtion
Chokes are designed, manufactured and tested in compliance with
EN50178.
Plastic materials comply with the following UL standards:
UL94 (file number E41871)
UL1446 (file number OBJY2.E329745)
Temperature class B (130 °C)
IN
UN OVCat III / II
LN
Ambient temperature Ta = – 40°C...+70°C (short-term +90°C)
Operating temperature Top = – 40°C...+130°C (short-term +150°C)
= nominal current in each winding
= operating voltage for overvoltage category III / II
= nominal inductance, tolerance +50% / -30 %
The standard chokes are designed for a temperature rise of
ΔT = 45….60 K at Ta=70 °C and I=IN in each winding. Data
derating is necessary for deviating ambient temperature or
deviating nominal current. Please contact VAC for further de-
tailed information.
