MPCO Toroid MnZn Ferrite Core have a distributed air gap and are available in material grades covering many applications. Typical applications include RF inductors and transformers, lamp dimmer chokes, 60Hz differential-mode EMI chokes and DC output chokes. MPCO issues two catalogues titled ‘RF Applications’ and ‘Power Conversion & Line Filter Applications’ The contents of each Catalogue is summarised below.
Composition >99% Iron
Permeabilities up to 100
High losses (840 mW/cm3)
Operating frequency to >100 KHz
BSat (Tesla) 1.5
Curie Temperature 770˚C
Shape formats: Toroidal; E core; bobbin core; etc.
Relative cost – Lowest of all Powder Cores
Advantages of Iron Powder Toroid MnZn O Core Ferrite
Wide range of different material mixes available to suit many different applications.
In general, iron powder cores are lower cost than alloy powder cores
Thermal aging needs to be considered when the core is exposed to prolonged elevated temperatures, this causes an irreversible increase in core loss over time. In the overwhelming majority of situations this is not going to be an issue, but if you think it might be, then it is worth considering an alloy powder alternative.
Toroidal Transformer Core Ferrite Ring , Power Transformer Toroid Ferrite Core – Toroidal Ferrite Core
The toroidal ferrite core uses a toroidal (ring or donut) shape ferrite core, which has the characteristics of isolating eddy current, low permeability, and suppressing interference. Due to the superior electrical performance of the ring, the usage of toroidal ferrite core is greatly increased
We provide toroidal ferrite cores in different sizes. You can use it in power transformers, current transformers, instrument transformers, inductors, chokes, ballasts, voltage stabilizers, welding transformers, broadband transformers, filters, etc. You can choose the bottle size that best suits your needs. In addition, if what you need is not in the list, please feel free to contact us. We can help you customize the toroidal ferrite core.
Toroids provide a convenient and very effective shape for many applications (wide band, pulse, power, and inductor). The continuous magnetic path yields the highest effective permeability and lowest flux leakage of any shape.
