메모

Output is with the the secondary windings connected in parallel.
When ordering, please specify packaging code: e.g. B0863-BLD
Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
DCR for the secondary is measured with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator
Leakage inductance is for the primary with all other windings shorted.
Turns ratio is with the secondary windings connected in parallel.
Isolation is measured from the primary, reset and bias windings to the secondary and drive windings.

종단 처리:

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

패키지:

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