1. When ordering, please specify packaging code:
FA2659-ALC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (175 parts 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 C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (750 parts per
full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
3. Leakage inductance measured at 100 kHz, 0.1 Vrms with secondary
pins shorted.
4. Based on Bsat of the core at 25°C and number of turns of the primary.
5. SRF measured with coils connected in series using an Agilent/HP 4192
or equivalent.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
