0201AF (0603)
Wirewound Ferrite Beads

  • Higher performance than other surface mount ferrite beads in the market
  • High impedance across a wide bandwidth; up to GHz band
  • Ferrite construction and heavy gauge wire for high current handling
  • Extremely low DCR for high current applications – as low as 0.15 Ohms
  • Eliminates high frequency noise in power supplies or RF signal isolation applications
  • RoHS Compliant, halogen free. 260°C compatible. Matte tin over nickel over
    silver-platinum-glass frit
  • Samples of all values available in Coilcraft Designer's Kit C471

1 When ordering, please specify packaging code: e.g. 0201AF-201XKRW
Packaging: W= 7" machine-ready reel
EIA-481 punched paper tape (2000 parts per full reel).
U = Less than full reel
In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter W instead.
2 Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
3 Q measured using an Agilent/HP 4991A with an Agilent/HP 16197 test fixture.
4 SRF is measured on an Agilent 8753D network analyser (or equivalent) with a Coilcraft SMD-D test fixture.Details
5 DCR measured at 25°C on a Cambridge Technology micro-ohmmeter (or equivalent) and a Coilcraft CCF858 test fixture, For other operating temperatures, use this DCR at Temperature calculator.
6 Irms: 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.
7 Ambient temperature range: −40°C to +85°C with Irms current
8 Storage temperature range: Component: −40°C to +100°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +100°C (Ambient + temperature rise)
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
12 Temperature coefficient of inductance (TCL): +25 to +150 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
