Wirewound Ferrite Beads:
Outperforming Traditional Chip Ferrite Beads

Coilcraft wirewound ferrite beads provide superior broadband performance
 
Wirewound versus Traditional Chip

Coilcraft wirewound ferrite beads provide superior broadband performance compared to both low- and high-DCR chip ferrite beads.

Figure 1 compares the Coilcraft 0402DF-12 wirewound ferrite bead to the lowest-DCR 0402-sized chip ferrite bead. The 0402DF offers higher impedance across the frequency range, providing a greater measure of filtering from 100 MHz and above.

Figure 2 compares the same Coilcraft 0402DF-12 wirewound ferrite bead to the typical high-DCR chip ferrite bead. The 0402DF maintains the same high frequency attenuation while providing higher current ratings and 40 percent better DCR.

  • Better attenuation across frequencies
  • Lower DC resistance (DCR)
  • Best performance in the smallest size
  • Higher current ratings without core saturation
