Amorphous E Cores


Amorphous E Cores with high saturate induction,excellent anti-bias current ability,easy for coil
assembling and high power design.


  • High saturation induction of 1.56 Tesla—Reducing component volume.

  • Low coercivity—Increasing component efficiency.

  • Low core loss—Reducing temperature rise in devices.

  • Variable permeability by different heat treatments—Satisfying various application requirements.

  • Excellent thermal stability—Having a highest service temperature of 130oC.
