1008AF (2520) Series

Wirewound Ferrite Beads

RoHS compliant halogen free
Our 1008AF Series wirewound ferrite beads feature heavy guage wire for high current handling. These are great for RF signal isolation and power supply filtering applications. This high-impedance series covers a wide range of  values from 59 Ohms to 720 Ohms at 10 MHz and comes with a tight ±5% standard tolerance on all values.
  • Higher performance than other surface mount ferrite beads in the market
  • High impedance across a wide bandwidth
  • Ferrite construction and heavy gauge wire for high current handling
  • Extremely low DCR for high current applications
  • Eliminates high frequency noise in power supplies or RF signal isolation applications

Notes
  1. When ordering, please specify termination and packaging codes: e.g. 1008AF-103XJRC
  2. Inductance measured at 2.5 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
  3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  4. DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  5. Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
  6. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

  • R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.
  • T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
  • S = Not RoHS Sn/Pb (63/37) (Special order, added cost)

Packaging:

  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). 
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
