0201AF (0603) Series

Wirewound Ferrite Beads

Our 0201AF (0603) Series wirewound ferrite beads have higher performance than others in the market, including high impedance across a wide bandwidth (up to GHz band). Ferrite construction and heavy gage wire means high current handling for their 0201 size. Extremely low DCR assures lowest insertion loss for high efficiency in mobile applications. These tiny beads eliminate noise in small power supplies and provide isolation of RF signals.

Higher performance than other surface-mount ferrite beads
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

Notes

When ordering, please specify packaging code: e.g. 0201AF-201XKRW
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.
SRF is measured on an Agilent 8753D network analyser (or equivalent) with a Coilcraft SMD-D test fixture.
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.
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.

Termination:

RoHS compliant matte tin over nickel over silver-platinumglass frit.

Packaging:

W = 7″ machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
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. 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 U to W.
