10 06/13 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 l value stresses in the core affect not only the mechanical but also the magnetic properties. it is apparent that the initial permeability is depe ndent on the stress state of the core. the higher the stresses are in the core, the lower is the value for the init ial 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 c hange 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 solderin g of the j-leg terminals may cause solderability problems at the transformer because of pollution wi th 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 di mensioning 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 c onsidered by increasing the hole diameter. cautions and warnings ferrites and accessories cautions and warnings
