Secondary Material Parameters
Although m'
for suppression applications, resistivity and Curie temperature
are ferrite material parameters that should be considered as well.
The Curie temperature is the transition temperature above which
the ferrite loses its magnetic properties. At this temperature the
component is no longer performing its intended function. Once
the material cools down below this temperature it will again
perform as before. For all Fair-Rite materials a minimum Curie
temperature is specified.
As mentioned previously, Fair-Rite manufactures two classes of
ferrite materials, MnZn and NiZn ferrites. The manganese zinc
materials have low resistivities whereas the nickel zinc materials
have high resistivities. For applications that use non-insulated
wires or for use as connector suppression plates, a ferrite
material with the highest resistivity is recommended. Fair-Rite’s
44 material is an improved 43 material by providing both in-
creased resistivity and Curie temperature. Components in the 44
NiZn material are catalog standard parts for connector plates and
wound parts such as PC beads and wound beads.
