注释

When ordering, please specify packaging code: e.g. DA2420-ALD
Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured on the primary windings with all secondary pins shorted.
Turns ratio is with the primary windings connected in parallel.
500 Vdc isolation from primary to secondary.

端子:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

包装:

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.
