FT Core/ET Core/transformer core/magnet cores/ pc40 ferrite core
General Introduction
- NiZn ferrite core is one kind of ferrite material, work steadily in big electric current, and magnetic properties of this ferrite chip are determined by chemical composition, porosity, grain size and micro structure.
- NiZn cores offer better miniaturization prospects, for its high electric resistance exceeding 10 Ohm-m, so that NiZn ferrite core is able to be wound directly by coils.
- The series of NiZn ferrite core is including DR core, RI core, DRWW core, RWW cores, RID core, RHH core, R4H core, F core, T core, etc. They are widely used in home communication appliance, computer etc area.
Features:
- FT cores and ET cores possess characters of ferrites, which exhibit high permeability and high resistivity.
- Also FT cores and ET cores are also reasonably stable (repeatable properties) over time and temperature.
- They are widely used for EMC Countermeasure, EMC filters and so on.
