High Flux Cores

High Flux cores are a kind of soft magnetic powder cores with nominal composition of 50% iron and 50% nickel.

Features:
– High saturation flux density of 15000 Gauss
– Best DC bias characteristics among all the soft magnetic powder cores
– Low core losses
– Higher energy storage capability than iron powder cores and ferrite cores
– Permeability from 26 to 125

Applications:
– PFC inductors
– Switching regulator inductors
– In-line noise filters
– Flyback transformers
– Pulse transformers

[1] In a High Flux core part number, “HHF” means it is a HGT High Flux core, the first three-digit string is outer diameter value (10^-2 inches) of that High Flux core before coating, the next three-digit string is its permeability value, the end with “B/C” means it has a different height with the same outer diameter.
* The data in this sheet are for reference only, more High Flux cores can be tailored as per customers’ specific requirements.
