Ni-Zn EMI Suppression Ferrite Cores

 

 

Split EMI

Suppression Cores

  

   

Split EMI Suppression Core (CF Series) consists with a nylon plastic case and two half ferrite cores. It can be installed to cable easily so don’t need cut the existing cable firstly and can be removed from cable without damage. Due to this feature, it can be installed after assembly products to save the time before marketing. If the design need higher impedance, increase the wire turns through the core is a fast and easy solution.

Shield & Toroidal Ferrite Cores

(RH&T Series)

  

     

Shield cores (RH series) and Toroidal cores (T series) are the EMI suppression cores with ring shape. RH cores are usually used for the cable assembly with plastic injection molding. The smaller RH cores are usually used to pass through beads of other elements or to be inductors by passing through wire. The T cores are mainly used for common mode or differential mode filter to suppression EMI. If the design need higher impedance, increase the wire turns through the core is a fast and easy solution.

D-Sub Connector 

Suppression Cores

  

      

The core (FH Series) is used in D-Sub, a connector for data transmission devices, to suppress the electromagnetic noise through the connector. FH series have 9, 15, 25, 37 holes and others design, can be insert the connector easily.

Flat Cable 

Suppression Cores

  

   

RP Series is a EMI suppression core with flat shape. It’s mainly used for the flat cable like FFC (Flexible Flat Cable) or FPC (Flex Printed Circuit) to suppress the electromagnetic noise through the cable in electric equipments. Due to this flat design, this ferrite core can be located in a narrow space inside the equipment very easily.

Ferrite Plate Cores

  

    

Ferrite Plate core (FP series) is one EMI suppression core with flat plate shape. It can suppress radiation noise from microprocessor when attached on the microprocessor, prevent resonance and suppress coupling when attached two microprocessors, suppress the electromagnetic noise through the cable from electric equipments when attached on the flat cable like FFC (Flexible Flat Cable) or FPC (Flex Printed Circuit). Also, it can avoid the NFC (Near Field Communication) mobile phone performance reduced because the battery, and restrict the magnetic fields occurred respectively from wireless charger base station and mobile device to protect others equipment.

Rod Cores

  

        

Ferrite Rod Core (R series) is a cylindrical ferrite core, can be easily assembly with a spring coil or wind wire directly. It's widely used for radio antenna, LF/HF RFID antenna, choke coil, inductor, DC power filter, DC signal filter and transformer. Due to the open magnetic structure, the core can accept large DC bias before saturate.
