메모

Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA. Drive winding output is 5 V, 10 mA.
When ordering, please specify packaging code: e.g. NA5730LD
Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc
Peak primary current drawn at minimum input voltage.
DCR for the primary and the secondary is with 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, measured with the windings connected in parallel and with the secondary windings shorted.
Turns ratio is with the primary windings and the secondary windings connected in parallel.
1500 Vrms, one minute isolation, primary and bias to secondary and drive.

종단 처리:

RoHS-compliant 260°C compatible. Tin-silver-copper 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 (175 parts 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.
