Max. operational temperature Continuous-epoxy Continuous-plastic casing short-term Permeability VITROPERM 500F VITROPERM 250F Core losses (100 kHz, 0.3 T) The superior material properties of nanocrystalline VITROPERM enable common mode chokes with high inductance/impedance with a small number of turns, resulting in reduced copper losses, low win- ding capacitance and excellent HF performance. Due to the high initial permeability, low winding ca- pacitance and a low Q-factor (above 100 kHz) VITROPERM CMCs offer a broadband insertion loss curve ranging from 10 kHz up to several MHz and improved attenuation behaviour at both low and high frequencies in comparison to conventional ferrite chokes with similar core dimensions and identical windings (see Fig. 13). Better attenuation properties and an extended ope- rating temperature range allow a reduction of the component volume by a factor of up to 3 or more under similar conditions. Note that the insertion loss curve of the small VITROPERM choke in Fig. 14 is similar to that of ferrite materials at frequencies of about 600 kHz – 1 MHz and is superior below 500 kHz and above 1 MHz. The excellent attenuation of VITROPERM CMCs simplifies the filter design in a wide frequency range. For laboratory tests, VAC offers different sample kits with selected standard cores and chokes.
