0402DF (1005) Series

Wirewound Ferrite Beads

Our 0402DF 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 0402 size. Extremely low DCR assures lowest insertion loss for high efficiency in mobile applications. These small beads eliminate noise in small power supplies and provide isolation of RF signals. They can withstand high temperatures and are AEC-Q200 Grade 1 (−40°C to +125°C) qualified.

Notes

When ordering, please specify termination and packaging codes: e.g. 0402DF-771XJRW
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 measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture, 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.

Termination:

R = RoHS compliant matte tin over nickel over silver-platinum-glass frit.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order)
P = non-RoHS tin-lead (63/37). (Special order)

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 = 7″ 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.
