注释

Output is with the secondary windings connected in parallel. Bias winding output is 12 V, 20 mA.
When ordering, please specify a packaging code: JA4667-ALD.
Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc.
DCR for the secondary is measured with the windings connected in parallel.
Leakage inductance is for the primary and is measured with the secondary shorted.
Turns ratio is with the primary windings and secondary windings connected in parallel.
1500 Vrms isolation from primary and bias to secondary.

端子:

RoHS-compliant 260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

包装:

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.
