0402DF

Ferrite Chip Inductors

Our 0402DF Series of wirewound ferrite chip inductors have the industry's lowest DCR in an 0402 size – up to 30% lower than the closest competitor. This series was developed for cellular applications for use as either filter elements, as one-pole filters, or as RF chokes in the cellular bands. These are ideal for use in mobile and infrastructure equipment.

The Industry’s lowest DCR in an 0402 package – up to 30% lower than the closest competitor
Developed for use in cellular applications:
As a filter element in bandstop and low pass filters

Notes

When ordering, please specify termination and packaging codes: 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 Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture.
DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
Current that causes a 15°C temperature rise from 25°C ambient. 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, added cost)
P = non-RoHS tin-lead (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 = 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.
