  1. When ordering, please specify packaging code: e.g. SBU9-6011R0LC
  2. Inductance tested at 1 kHz, 1 Vrms, and it is measured on Agilent/HP 4263B LCR meter or equivalent.
  3. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  4. DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Interwinding isolation (hipot) tested for one minute.


  • RoHS compliant tin-silver over copper.


  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (350 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 D.
