Notes

When ordering, please specify termination and packaging codes: e.g. WBC16-1TLC
Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/ HP 4192 or equivalent.
DCR measured at 25°C on a micro-ohmmeter. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Impedance ratio is for the full primary winding to the full secondary winding.
DC imbalance is the maximum difference in current measured at pins 1 and 3 with the source at pin 2. Inductance drop is 15% at maximum imbalance.

Termination:

L = RoHS compliant tin-silver-copper (95.5/4/0.5) over silver-platinum-glass frit.
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (750 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel).
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 C.
