0603AF (1608) Series

Wirewound Ferrite Beads

Our 0603AF Series of wirewound ferrite beads feature heavy guage wire for high current handling and are great for RF signal isolation and power supply filtering applications. This series covers a wide range of impdedance values from 9 Ohms to 3800 Ohms at 100 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; up to GHz band
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

When ordering, please specify termination and packaging codes: e.g. 0603AF-103XJRW
Inductance measured at 0.1 Vrms, using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
DCR measured at 25°C using a Cambridge Technology Micro-ohmmeter. 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. Because of their open construction, these parts will not saturate.
Each part is marked with a single dot. The color dots are not unique identifiers and correspond to multiple inductance values.

Termination:

R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

Q = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
P = Not RoHS Sn/Pb (63/37) (Special order, added cost)

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).
Y = 13″ machine-ready reel. EIA-481 punched paper tape. Factory order only, not stocked (10000 parts per full reel).
U = 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.
