Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape.
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.

2. Inductance is for the primary, measured on an Agilent/HP 4284 at 250 kHz,
0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 2 and 3 at 250 kHz, 0.1Vrms,
0 Adc with all secondary pins shorted.
4. DC current that causes an inductance drop of 30% (typ) from its value
without current
5. Electrical specifications at 25°C.
