Notes
  1. When ordering, please specify termination and packaging codes: e.g. PWB-1.5-CLD
  2. Inductance tested at 130 kHz, 0.1 Vrms, 0 Adc.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.

Termination:

  • L = RoHS compliant tin-silver-copper over tin over nickel over phos bronze.
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • C = 7″ machine ready reel
    EIA-481 embossed plastic tape, 250 parts per full reel.
  • B = Less than full reel
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape.  Factory order only, not stocked  (1000 parts per full reel).
