These are amorphous cores which include amorphous saturable core (FBC), common-mode choke coil (FTF) etc. These amorphous cores are in different sizes and they made of different materials. The cores can be used to smoothen switching power supply outputs.
- Small and lightweight when compared with ferrite cores and dust cores
- Help stabilize inductance
- Excellent DC bias characteristics
- Amorphous toroidal without gap core
- Low core loss at a high frequency
