注释

When ordering, please specify packaging code: e.g.CX9721-ALD
Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
Leakage inductance measured at 100 kHz, 0.1 Vrms, between pins 1 and 2 with all other pins shorted.
4000 Vrms, one minute isolation from the primary and auxiliary winding to the secondary.

端子:

RoHS-compliant. 260°C compatible. RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations.

包装:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (700 parts per full reel).
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.
