Toroidal Soft Magnetic Amorphous Inductor Cores for Car Audio

Amorphous Cores for Car Audio Inductor:

Fe-based amorphous core applied in car audio inductor provides the good frequency property, AC/DC superposition characteristics and low core loss. And the wide permeability range from 120 µ to 1200 µ . It is a good choice for the inductor, choke and filters in high frequency and AC/DC superposition situation, and with better price than FeNiMo, FeNi and FeSiAl powder cores.

Features:

• High saturation flux density Bs, low Hc, Low loss.
• Excellent Anti DC bias property.
• High permeability of 120 to 1200µ, Less wire winding turns.
