JHCOILS: Professional Supplier of Transformer Ferrite Core
Due to years of experience in the field of inductive components, JHCOILS currently supply a wide range of high frequency ferrite core in a variety of types.
Types of Ferrite Core
One is power ferrite cores, which are mostly used for compact transformers;
Another one is high-permeability ferrite cores, which are widely used for digital communication pulse transformers(signal transformers).
Material of Ferrite CORE
MnZn ferrites are a class of soft magnetic materials that have very good electrical and magnetic properties. MnZn ferrite core is consisting of a combination of iron oxide,manganese oxide and zinc oxide. The advantageous properties of MnZn ferrites include high value of resistivity, permeability, permittivity, saturation magnetization, low power losses and coercivity. The above mentioned advantageous features of MnZn ferrites make them suitable for the use in various applications. MnZn ferrites are used widely in electronic applications for making transformers, transducers and inductors.
