Application information for the available powder grades:
-
AS: Sendust cores are made of alloy powders with specific composition of Fe-9.6%Si-5.4%Al and feature almost zero magnetostriction. As a
result, sendust cores can work without audible noise and are the high C/P choice of power choke design, very suitable for application
frequency range 50KHz~100KHz.
-
AK: X-Flux cores are made of alloy powders with specific composition of Fe-3~6.5%Si and feature very excellent DC-bias properties, very
suitable for hi-power applications within 20~40KHz and the first choice for filter choke applications.
-
AG: Super Dust cores are made of alloy powders with specific composition of Fe-9.6%Si-5.4%Al by gas atomized powder preparation and
feature almost zero magnetostriction, featuring excellent DC-bias property and very low core loss, are the best alternative choice to expensive
MPP and APM(Amotech) cores.
-
AH: High Flux cores are made of metal alloy powders with composition of Fe-50%Ni and feature the best DC-bias properties and lower
core loss, the first choice for the applications of hi-power density modules.
