Miniature RF Chokes

Our 026011F Series of miniature wirewound RF chokes are an optimized 0201 size at 0.7 × 0.3 × 0.55 mm and feature high impedance for RF isolation in cellular applications. This series offers the industry's highest inductance values in 0201 size – up to 560 nH. The ferrite construction assures high current handling and lowest possible DCR.

Notes

When ordering, please specify packaging code: e.g. 026011F-561XJRY
Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture with an Agilent/HP 4287A impedance analyzer.
SRF is measured on an Agilent/HP 8753ES (or equivalent) with a Coilcraft SMD-D test fixture.
DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent) with a Coilcraft CCF1192 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
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.

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.
