Toroidal Core for Filter Inductor
Characteristics:
High saturation magnetic induction (1.56T), low loss at high
frequency, wide frequency range. Used for smooth filter inductor, choke
and energy storage inductor of high frequency switched mode power
supply.
Differential Mode Amorphous
Core/Inductor
Characteristics:
The core with a gap has constant inductance, large D.C. magnetic
bias resistance and low loss. Applied for inductor cores for various power
supply.
