0805RB Series

Wirewound Ferrite Beads

RoHS compliant halogen free
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

Notes
  1. When ordering, please specify termination and packaging codes: e.g. 0805RB-272XMRC
  2. Inductance measured at 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
  3. SRF measured using Agilent/HP 8753D network analyzer with Coilcraft SMD-D test fixture.
  4. DCR measured on Cambridge Technology Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  5. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. 
  6. Maximum current that can be applied at 85°C.
  7. Maximum current that can be applied at 125°C.
  8. Each part is marked with a single dot. The color dots are not unique identifiers and correspond to multiple inductance values. Details
