메모

When ordering, please specify packaging code: e.g. DA2383-ALD
Inductance is for the primary, measured at 200 kHz, 0.2 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured on the primary winding with all secondary pins shorted.
1500 Vrms, one minuteisolation from primary and aux to secondary.

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 (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.
