Toroidal Amorphous Cores

Applications:

Noise suppression in car audio devices.

Choke coils for DC/DC converters.

Normal mode choke coils.

Output smoothing choke coils for SMPS.

Features:

Lower core loss at high frequency enabling low temperature rise.

No leakage magnetic flux due to gapless structure.

Excellent DC bias characteristics.

High magnetic permeability range from 250 to 1200, which lead to the reduction in number of turns
