0805RB Series

Wirewound Ferrite Beads

Coilcraft 0805RB Series wirewound beads are an excellent choice to isolate AC noise from DC bias or DC power injection lines in baseband RF amplifier circuits. They provide superior performance compared to traditional thick-film ferrite beads, including optimized impedance over a wide frequency range. They also offer high Self Resonant Frequency, and their low DCR makes them an excellent choice for high current applications.

Superior performance to traditional thick-film chip ferrite beads in the market
Optimized high impedance over a wide frequency range
High SRF and low DCR combination for high- frequency and high-current applications without core saturation
