Notes

When ordering, please specify a packaging code: B0695-ALD
Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
DCR for the secondary is per winding.
Leakage inductance measured between pins 4 and 6 with all other pins shorted.
Turns ratio is with the secondary windings connected in parallel.
Isolation is measured from the primary and bias windings to the secondary.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (175 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.
