High Permeability MnZn Toroidal Ferrite Ring Core – Toroidal cores are used as power shapes in electric circuits such as inductors and transformers. They are an ideal material to use at low frequencies where large inductances are required. The cores offer the advantage of material permeability and have a uniform cross-sectional area. They do not have any gaps, so the leakage is very low. This is why the toroidal core windings are commonly used in current and instrument transformers.

Manganese Zinc (MnZn) Ferrites
This general type of ferrite can be manufactured in several different vastly different grades by altering its composition and processing. Initial relative permeability (at 25 degrees Centigrade) can range from several hundred to twenty thousand. Saturation (at 25C) ranges from 3.5 to 5 kilogauss. The curie temperature can range from 100 to 300 degrees Centigrade. Material grades have been developed for particular groups of applications such as power, broadband, E.M.I./R.F.I. filtering, ripple filtering, tuning, and others. The useful frequency range for most of these materials is 1 megahertz and less (with suitable flux density de-rating), but some types approach 9 megahertz. Manganese Zinc ferrites have very low porosity. Ferrite Toroids Toroidal Cores for Transformers
Component of MnZn core
The present MnZn core relates to a typical oxide magnetic material having soft magnetism, and more particularly to MnZn material and soft ferrite material suitable for low-loss materials for use in magnetic regulators, switching power supplies, various inductance elements, impedance elements for EMI countermeasures, electromagnetic wave absorbers, and so forth. An MnZn ferrite core is including base components of 44.0 to 49.8 mol % Fe2O3, 4.0 to 26.5 mol % ZnO, 0.8 mol % or less Mn2O3, and a remainder of MnO; MnZn power is containing 0.20 (0.20 excluded) to 1.00 mass % CaO as additive; and MnZn material is having a resistivity of 1.5 × 10<4> OMEGA m or more and a surface resistance of 1.5 × 10<7> OMEGA or more.

Advantages of MnZn ferrite core
MnZn ferrite core have many advantages: High resistively, Wide range of operating frequencies– The suitable frequency range for this soft ferrite material runs from 1kHz to 1GHz. Low loss combined with high permeability, Time and temperature stability, Large material selection, Versatility of core shapes, Low cost, Light weight, Ferrites may be, and are, “tailor-made” within technological limits, to meet desired characteristics for electronic components. This is accomplished principally by varying the chemical composition of the materials and by making appropriate changes in processing procedures. Power Inductor Toroid Ferrite Core Ring Magnets
