1. When ordering, please specify a packaging code:
A0009-ALD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (150 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 100 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured at 100 kHz, 0.1 Vrms from pins 1 to 4
with all other pins shorted.
4. Isolation measured from pin 1 to pins 5 and 6; from 2 to 5 and 6; and
from pins 1, 2, 5 and 6 to the core for one minute.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
This surface mount flyback transformer is designed for
use with Texas Instruments LM5000 DC/DC regulator.
The core completely encloses the windings to minimize
EMI interference. The transformer features very low DCR,
500 Vrms isolation and a leakage inductance rating of just
1.0 µH. Coilcraft can also custom engineer a transformer
to meet your specific requirements.
