1. When ordering, please specify a packaging code:
HA3648-BLD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 per full reel).
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 measured on an Agilent/HP 4284 between pins 3 and 4 at
250 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 3 and 4 at 250 kHz,
0.1 Vrms, 0 Adc with pins 6, 8 and 10 shorted.
4. DCR for the secondary is from pin 6 to pin 10.
5. Electrical specifications at 25°C.
