MAGAMP - Square Loop Cores
  [hide]

Metglas® SQUARE LOOP magnetic cores are specifically designed to exhibit an extremely square dc hysteresis loop and high BSAT resulting in the following important benefits:

  • Low Saturated Permeability
  • Low Coercive Field - indicating a small reset current
  • Low Profile - enabling weight and volume reduction of up to 50%
  • Low Loss - resulting from micro-thin Metglas® ribbon (18µm)
