Notes

When ordering, please specify termination and packaging codes: e.g. PWB-1.5-CLD
Inductance tested at 130 kHz, 0.1 Vrms, 0 Adc.
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, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13″ machine ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
