, 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 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 destroyed. ? too strong winding forces may blast the flanges or squeeze the tube that the cores can not be mounted any more. ? too long soldering time at high temperature (>300 c) may effect coplanarity or pin arrange- ment. ? 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. display of ordering codes for epcos products the ordering code for one and the same product can be represented differently in data sheets, data books, other publications and the website of epcos, or in order-related documents such as shipping notes, order confirmations and product labels. the varying representations of the ordering codes are due to different processes employed and do not affect the specifications of the respective products . detailed information can be found on the internet under www.epcos.com/orderingcodes. cautions and warnings ferrites and accessories cautions and warnings symbol meaning unit a a e a l a l1 a min a n a r b ' b b ?
