Toroidal amorphous cores

Toroidal amorphous cores Product Description

---

 

 

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.

 

Toroidal amorphous cores 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.
