026011F (0703) Series

Optimized Wirewound Ferrite Beads

Our 026011F (0603) Series wirewound ferrite beads achieve even higher optomized impedance and lower DCR than our 0201AF Series in a slightly taller height, still only 0.55 mm max. Ferrite construction and heavy gage wire means high current handling for 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.

Optimized 0201 size – 0.7 × 0.3 × 0.55 mm high
High impedance for RF isolation in cellular applications
Higher inductance values than other 0201 inductors – up to 560 nH
Ferrite construction for high current handling

Notes

When ordering, please specify packaging code: e.g. 026011F-561XJRY
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 at 25°C on a Keithley 580 Micro-ohmmeter (or equivalent) and a Coilcraft CCF1192 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
Irms: Current that causes a 15°C temperature rise from 85°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. Because of their open construction, these parts will not saturate.

Termination:

RoHS compliant, matte tin over nickel over silver platinum-glass 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).
Y = 7″ machine-ready reel. EIA-481 punched paper tape (10,000 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.
