  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.


  • 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)
