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, reduction in number of turns.
