Hanau, Germany Vacuumschmelze GmbH has developed a standard series of common mode chokes with nanocrystalline VITROPERM® cores. In addition to the superior properties at low and medium frequencies these chokes have an optimized performance in the high frequency range. Due to their broadband attenuation characteristic they are particularly suitable for use in switched mode power supplies, solar converters, uninterruptible power supplies or for frequency drives. The series consists of single phase CMC for rated currents from 2 A to 32 A and open, non-moulded 3-phase chokes for rated currents from 6 A to 40 A. The chokes are designed for operating voltages from 250 V or 500 V in compliance with the EN 50178 and EN 60950 safety-related standards. All chokes are manufactured according to the 2002/95/EC ROHS directives. A set of selected common mode standard chokes and nanocrystalline tape-wound cores have been assembled in an EMC kit which is available now.
