Constant inductance with annular magnetic core of amorphous and nanocrystalline incision, with high saturation magnetic induction intensity, wide range of constant bias magnetic field, high linear magnetic permeability, low loss at high frequency, excellent frequency characteristic and the temperature stability.

Its permeability can control the change over a very wide range (u from 120 to 120), resistant to different range of bias current ampere turn (partial) magnetic field, suitable for all kinds of high frequency, ac/dc superposition application occasions of inductors, with high cost performance, far better than the iron nickel molybdenum and silicon aluminum magnetic iron powder core.

This product is widely used in output filter inductance, differential mode inductance, frequency conversion air conditioning PFC inductance.
