Notes

Output is with the secondary windings connected in parallel. Output of the bias winding with a 15 V, 0.2 A
When ordering, please specify packaging code: e.g. C1048-ALD
Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
DCR is for both windings of the secondary connected in parallel.
Leakage inductance is for the primary winding with the secondary windings shorted.
Turns ratio is with the secondary windings connected in parallel
1500 Vrms, one minute primary to secondary isolation.

Termination:

RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (200 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.
