What is A MnZn Transformer core

MnZn Transformer core is a type of soft ferrite. It is a spinel structure. The oxides of iron, manganese and zinc and their salts are made by a ceramic process. It has a high initial permeability. At present, These ferrites include the model as toroidal Ferrite core,EE ferrite core,PQ ferrite core,EC ferrite core,EFD ferrite core,EI ferrite core,EDR ferrite core,RM ferrite core,URS ferrite core,EPC ferrite core,UU ferrite core,I ferrite core,PM ferrite core,UYF ferrite core and ED Ferrite core,most of them are used in the frequency range of 1 kHz to 10 MHz. small broadband transformers, pulse transformers, micro inductors, and low frequency transformers. It can also be used as a normal mode , common mode choke coil , small filter,EMI components, heads and antenna rods can be fabricated.etc.


MnZn transformer core

  • Toroid Ferrite Core
    POT series MnZn transformer core are commonly used for filters for telecommunication equipment,and various kinds of inductors and transformers etc. It is a polycrystal, sintered material with high electrical resistivity. The high resistance of ferrite makes eddy current losses extremely low at high frequencies.
  • Ferrite Core Inductors
    EPC series MnZn transformer core are commonly used for various kinds of transformers , chokes and various kinds of electronic instruments, etc. It is a polycrystal, sintered material with high electrical resistivity. The high resistance of ferrite makes eddy current losses extremely low at high frequencies.
  • Ferrite E Core
    EP series MnZn transformer core are commonly used for various kinds of transformers , chokes and various kinds of electronic instruments, etc.
  • Ferrite Core Antennas
    EI series MnZn transformer core are commonly used for various kinds of transformers , chokes and various kinds of electronic instruments, etc. It has high permeability, low core loss factor
  • Ferrite Clamp on Core
    EFD series MnZn transformer core are commonly used for Auxiliary powr transformer,main power transformer,choke coils and various kinds of electronic instruments, etc. It has high permeability, low core loss factor, and low price and High Frequency.This EFD core is made by MnZn material which permeability from 2000 to 15000.

Applications

MnZn Transformer core have a wide range of applications as follows:

1. Transformer/filter components in computer network cards.

2. Various audio transformers used in communication equipment such as program-controlled switches, usually adopting EP type high magnetic permeability core, which is 10000—12000.

3. Broadband transformers, including wideband signal transformers and pulse transformers, are indispensable for digital signals or analog signals to be transmitted in a wideband digital network.

4. Electromagnetic compatibility technology calls for the development of high-performance anti-EMI components.

That is mainly used for small broadband transformers, pulse transformers, micro inductors, and low frequency transformers. It can also be used as a normal mode and common mode choke coil and small filter. EMI components, heads and antenna rods can be fabricated.etc.
