Cost

For not the normal shape of Amorphous cores,we can produce with customers’ requirement.

Oval-shaped, Rectangle,Tiny shape of the cores and so on.For example,Tiny magnetic cores.

can be used under high frequency.

Characteristics  

  • 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.

Core Features

  • The tiny magnetic core made by Co-base amorphous alloy and Fe-base nanocrystal alloy has great permeability and high rectangle ratio.

  • Its volume is small so it can be popularly used in hi-frequency switch power and other electric equipment to reduce the noise and the output hi-frequency wave.

  • And it has lower loss than the circuit with resistor.

  • And also it only need a small room so it can be directly interlinked to the foot of transistor.

"Amorphous Inductor"

Applications

  • The spikes-suppressor of high frequency switch power supply.

  • EMI high frequency resistance filter

  • Other electric equipment
