メモ

When ordering, please specify packaging code: e.g. DA2257-ALD
Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary winding with all other pins shorted.
2000 Vrmsisolation from primary and aux to secondaries.

終端処理:

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

パッケージ:

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.
