Special Shape Amorphous Cores
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.
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.

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