1. When ordering, please specify packaging code:
C1099-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 is for the primary, measured at 300 kHz, 1.0 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. Primary DCR is measured with the windings connected in series. Sec-
ondary DCR is measured with the windings connected in parallel.
5. Leakage inductance is for the primary winding with the secondary wind-
ing shorted.
6. Turns ratio is for the primary connected in series and the secondary con-
nected in parallel.
7. Output of the secondary is with the windings connected in parallel. Bias
winding output is 14 V.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
