1K101 Amorphous E Core

1K101 Amorphous E Core

MagComponent's 1K101 series amorphous E cores are manufactured using iron-based amorphous alloy ribbon. This material features extremely high saturation flux density and ultra-low core losses, making it an ideal alternative to traditional silicon steel and ferrite cores.

High saturation flux density: 1.56 T (enables smaller device size)
Ultra-low losses: 1/5 to 1/10 of silicon steel at same frequency
Excellent temperature stability: Curie temperature 410°C
E-core structure: Easy coil winding and automated production
