  1. When ordering, please specify packaging code: e.g. B0310-ALD
  2. Inductance measured between pins 1 and 3 at 250 kHz, 0.1 Vrms, 0 Adc
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.


  • RoHS-compliant. 260°C compatible.
    Planar transformers: Matte tin over nickel over brass terminations
    MSS6132: Gold over nickel over phos bronze terminations
    Output choke inductors - Tin-silver over tin over nickel over phos bronze terminations


  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (250 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.
RoHS compliant
