4. Seite 4 4 - VITROPERM® CM Chokes & Cores 2005 - Seite 4 VITROPERM ® Common Mode Chokes Properties & Benefits Material:high initial permeability µ i - low µ(f) - low Q-factor - low temperature dependency - high upper application temperature - high saturation flux density B s CMC:high low-frequency attenuation - small size - low no. of turns – low winding capacity – high high-frequency attenuation – easy to design – smooth and steady damping up to high temperatures Filter:easy to design – less stages possible - smaller volume – lower costs VITROPERM®CMC
