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 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 is the value for the initial permeability. Thus the embedding medium should have the greatest possible elasticity. For detailed information see chapter “Definitions”, section 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 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. 4 06/13 Ferrites and accessories Symbols and terms Symbols and terms A Ae AL AL1 Amin AN AR B   BDC BR BS C0 CDF DF d Ea f fcutoff fmax fmin fr fCu g H  HDC Hc h 2 I IDC J k k3 k3c L Meaning Cross section of coil Effective magnetic cross section Inductance factor AL = L/N2 Minimum inductance at defined high saturation Minimum core cross section Winding cross section Resistance factor AR = RCu/N2 RMS value of magnetic flux density Flux density deviation Peak value of magnetic flux density Peak value of flux density deviation DC magnetic flux density Remanent flux density Saturation magnetization Winding capacitance Core distortion factor Relative disaccommodation coefficient DF = Disaccommodation coefficient Activation energy Frequency Cut-off frequency Upper frequency limit Lower frequency limit Resonance frequency Copper filling factor Air gap RMS value of magnetic field strength Peak value of magnetic field strength DC field strength Coercive field strength Hysteresis coefficient of material Relative hysteresis coefficient RMS value of current Direct current Peak value of current Polarization Boltzmann constant Third harmonic distortion Circuit third harmonic distortion Inductance 5 06/13 Unit mm2 mm2 nH nH mm2 mm2 = Vs/m2, mT Vs/m2, mT Vs/m2, mT Vs/m2, mT Vs/m2, mT Vs/m2, mT Vs/m2, mT F = As/ V   J Hz Hz Hz Hz Hz  mm A/m A/m A/m A/m cm/A cm/A A A A Vs/m2 J/K   H = Vs/A Ferrites and accessories Symbols and terms L0 LH Lp Lrev Ls le lN N PCu Ptrans PV PF Q R RCu Rh Ri Rp Rs Rth RV s T TC t tv
