VITROPERM 500 F - NANOCRYSTALLINE TAPE-WOUND CORES FOR COMMON MODE CHOKES - PLASTIC CASE
Common Mode Chokes with toroidal tape wound cores of VITROPERM allow the effective attenuation of asymmetrical and conducted high frequency noise. The high permeability of the nanocrystalline core material achieves superior characteristics at low and middle frequencies, as well as in the high frequency range, when an optimized winding arrangement is chosen. In comparison to conventional ferrite, advantages over the entire frequency range are obtained. Further informations are available in our application notes (1.54 MB, PDF) +.
All tape-wound cores listed below are inserted in plastic cases. These allow best magnetic properties, offer good mechanical protection and are suitable for direct winding. Epoxy coated cores are listed in our VF-Core Series.
We recommend to examine the theoretical calculations experimentally. To examine theoretical calculations experimentally, VAC offers special sample kits consisting of cores and components: EMC - Kit 2004 and Core Sample Kit VITROPERM (0.12 MB, PDF) +.
The main areas of application are:
- Switched-mode power supplies
- Uninterruptible power systems (UPS)
- Pulsed welding equipment
- Power inverter (e.g. solar inverter)
- Wind generators
- Frequency converter
