Application area:

Switch power transformer and Pulse transformer iron core
Power transformer , precision current mutual inductor iron core
Leakage protection switch mutual inductor iron core
Filtering inductance, storage inductance, the electric reactor iron core
EMC common mode inductance and differential mode inductance iron core
Saturable reactor, magnetic amplifier, Spike killer, Pulse Compressor iron core and magnetic bead

Features:

High Saturation magnetic induction - reduce transformer volume
High magnetic permeability low coercive force- improve transformer efficiency, mutual inductor sensitivity, reduce coil distribution parameters
Low loss- reduce transformer temperature rise
Good temperature stability - under 130ºC for long-term work
Lower price - has the best cost performance of all the metal soft magnetic material
