1. When ordering, please specify a packaging code:
JA4309-ALD
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 2 and 4 at
200 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 2 and 4 at 100 kHz,
0.1 Vrms, 0 Adc with all secondary pins shorted.
4. DCR for the secondary is for each winding.
5. Electrical specifications at 25°C.
