1. When ordering, please specify packaging code:
GA3372-ALD
Packaging: D = 13″ 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 D instead.
2. Inductance measured at 250 kHz, 0.7 Vrms, 0 Adc.
Dot above pin1
3. Peak primary current drawn at minimum input voltage.
4. DCR for the secondary is with windings connected in parallel.
5. Leakage inductance is for the primary and is measured with the secondary shorted.
6. Turns ratio is with the secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel. Auxiliary winding
output is 10 V, 20 mA.
