Ferrites and accessories

Cautions and warnings

Mechanical stress and mounting

Ferrite cores have to meet mechanical requirements during assembling and for a growing number

of applications. Since ferrites are ceramic materials one has to be aware of the special behavior

under mechanical load.

As valid for any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing

or tensile load. Especially high cooling rates under ultrasonic cleaning and high static or cyclic loads

can cause cracks or failure of the ferrite cores.

For detailed information see chapter

“Definitions”,

section 8.1.

Effects of core combination on A

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 is the value for the initial permeability. Thus the embedding medium should

have the greatest possible elasticity.

For detailed information see chapter

“Definitions”,

section 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 irreversible in high magnetic fields.

Processing notes

– The start of the winding process should be soft. Else the flanges may be destroid.

– To strong winding forces may blast the flanges or squeeze the tube that the cores can no more

be mount.

– To long soldering time at high temperature (>300 °C) may effect 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 pollution with Sn oxyd of the tin bath or burned insulation

of the wire. For detailed information see chapter

“Processing notes”,

section 8.2.

– The dimensions of the hole arrangement have fixed values and should be understood as

a recommendation for drilling the printed circuit board. For dimensioning the pins, the group

of holes can only be seen under certain conditions, as they fit into the given hole arrangement.

To avoid problems when mounting the transformer, the manufacturing tolerances for positioning

the customers’ drilling process must be considered by increasing the hole diameter.
