1. When ordering, please specify packaging code:
FA2470-ALD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (350 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 D instead.
2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
3. Ipk is peak primary current drawn at minimum input voltage.
4. Leakage inductance measured between pins 1 and 3 with pins 4 and 6
shorted.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Core material Ferrite
Interwinding isolation 1500 Vdc
Terminations RoHS tin-silver over tin over nickel over phos bronze.
Other terminations available at additional cost.
