  1. When ordering, please specify termination and packaging codes: e.g. DO1607B-685MLC
  2. Inductance tested at 100 kHz, 0.1 Vrms  using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR tested at 25°C on a Cambridge Technology 510-A with Coilcraft CCF859 fixture. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current.
    Temperature derating curves.
  5. 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. Temperature derating curves.


  • L = Gold over nickel over moly-manganese.
  • 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)


  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (750 per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).

Resistance to soldering heat:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
