Amorphous Multiple Air Gap C-Core Product Description
An Amorphous Multiple Air Gap C-Core is a rectangular C-shaped magnetic core made from a rapidly cooled, amorphous (non-crystalline) metal ribbon, which is then cut and separated into multiple segments to create deliberately engineered air gaps.
This design is used in high-frequency power supplies and inverters to improve performance, particularly for inductors and transformers, by controlling magnetic flux, reducing core losses, and improving DC offset saturation resistance.
Amorphous Multiple Air Gap C-Core Feature:
*Core material and grade: Fe-based amorphous alloy,1k101
*High saturation induction.for high satured current,small core volume
*Multiple air gaps .for low noise and Excellent DC-bias characteristics.
*Lower temperature rising for single gap.
Amorphous Multiple Air Gap C-Core Application:
*Output smooth filter choke for switched mode power supply
*PFC boost choke for solar inverters, EV charging pile,
*AC inverter choke. For PV inverters, APF
*Robotic systems
*Frequency converters.
