0402DF

Ferrite Chip Inductors

RoHS compliant halogen free AEC-Q flag
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
    As a one pole filter or RF choke in cellular bands
  • Ideal for use in mobile and infrastructure equipment.
  • Higher inductance values than other 0402 inductors – up to 3300 nH
  • Ferrite construction for high current handling
  • Can also be used for ground-to-ground isolation
  • AEC-Q200 Grade 1 (−40°C to +125°C)

Notes
  1. When ordering, please specify termination and packaging codes: 0402DF-771XJRW.
  2. 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
  3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture.
  4. DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
  5. 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).
  • U = Less than full reel
    In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter W instead.
