Round cable ferrite bead

Common applications:

  • Impedance matching
    In power HF transformers on the output of MOS-FET or bipolar transistors, the maximum power is estimated at about 200/400W, see application example

  • Choke and EMI filter up to 500 MHz
    Typical impedance
    Frequency 1 turn 3 turns
    10 MHz 105Ω 900Ω
    25 MHz 171Ω 1539Ω
    100 MHz 250Ω 650Ω
    250 MHz 255Ω 250Ω
     
  • Common mode rejection choke on coaxial cables
    When on the screen of a coaxial cable there is a RF current it is necessary to include a common mode choke, this situation often happens when you change from an unbalanced impedance  to a balanced one (coaxial cable on balanced dipole antenna). This ferrite is compatible with all coaxial cables up to 6mm diameter including RG58, RG223, RG142, etc..., for this application it is recommended a choke impedance of at least 10 times higher than that of the coaxial cable

Example of application on coaxial cable
