Ferrites and accessories
Cautions and warnings
Mechanical stress and mounting
Ferrite cores have to meet mechanical requirements during assembly and for a growing number of
applications. Since ferrites are ceramic materials one has to be aware of their special behavior under
mechanical load.
Just like any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing or
tensile load. Especially fast cooling rates under ultrasonic cleaning, high static and cyclic loads can
cause cracks or failure of the ferrite cores.
For detailed information see Data Book 2007, chapter “General – Definitions, 8.1”.
Effects of core combination on AL value
Stresses in the core affect not only the mechanical but also the magnetic properties. It is apparent
that the initial permeability is dependent on the stress state of the core. The higher the stresses are in
the core, the lower the value for the initial permeability. Thus, the embedding medium should offer the
greatest possible elasticity.
For detailed information see Data Book 2007, chapter “General – Definitions, 8.2”.
Heating up
Ferrites can run hot during operation at higher flux densities and higher frequencies.
NiZn-materials
The magnetic properties of NiZn-materials can change irreversibly when exposed to strong magnetic
fields.
Processing notes
The start of the winding process should be soft. Otherwise, the flanges may be destroyed.
Excessive winding forces may damage the flanges or squeeze the tube so that the cores can no
longer be mounted.
Excessive soldering time at high temperature (>300 °C) may affect coplanarity or pin arrangement.
Not following the processing notes for soldering of the J-leg terminals may cause solderability
problems at the transformer because of contamination with tin oxide (SnO) from the tin bath or burned
insulation from the wire. For detailed information see Data Book 2007, chapter “Processing notes,
2.2”.
The dimensions of the pin hole arrangement are fixed and should be understood as an ideal
recommendation for drilling the printed circuit board. In order to avoid problems when mounting the
transformer, customers should make allowances for manufacturing tolerances in the drilling and pick-
and-place processes by increasing the diameter of the pin holes
