The BournsĀ® SRF Series common mode chokes are wound on a high permeability ferrite toroid core with high impedance (5K ohms min.) to control low frequency range (300 KHz) EMI interference. As result of the high permeability core, these common mode chokes feature low winding resistance to preserve data line signal integrity. The BournsĀ® SRF common mode series chokes are encapsulated or assembled in a plastic case to protect the coil from severe environments.
