Notes
  1. When ordering, please specify tolerance, termination and packaging codes: e.g. 1812SMS-R12JLC
  2. Inductance tested at 150 MHz on an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft SMD-A test fixture and correlation.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q tested at 150 MHz on an Agilent/HP 4291A Impedance Analyzer with an Agilent/HP 16193 test fixture or equivalent.
  5. SRF tested on the Agilent/HP 8753D Network Analyzer or equivalent and a Coilcraft CCF1248 test fixture.
  6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
  7. 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.

Tolerance:

  • = 2%, = 5% (Table above shows stock tolerances in bold.)

Termination:

  • L = RoHS compliant tin-silver (96.5/3.5) over copper.
  • T = RoHS tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost)
  • S = non-RoHS tin-lead (63/37) over copper. (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel.
    EIA-481 embossed plastic tape, 500 parts per full reel. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = 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 B to C.
  • D = 13" machine-ready reel.
    EIA-481 embossed plastic tape. Factory order only, not stocked, 2000 parts per full reel.
