注释
  1. When ordering, please specify termination and packaging codes: e.g. 0402AF-561XJLW
  2. Inductance measured at 7.9 MHz, 0.1 Vrms, using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces.
  3. Tolerances in bold are stocked for immediate shipment.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  5. DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  6. 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.

端子:

  • L = RoHS compliant gold over nickel over silver-palladium-glass frit.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

包装:

  • 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).
  • Q = 7" machine-ready reel
    EIA-481 punched paper tape (5000 parts per full reel).
  • 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.
