1. When ordering, please specify a packaging code:
HA4000-AL
D
Packaging: D =13
″ machine ready reel. EIA-481 embossed plastic
tape (200 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 across pins 2 and 4 at 200 kHz,
0.1 Vrms, 0 Adc.

Developed for the National Semiconductor LM5027
Voltage Mode Active Clamp Controller.
Chosen by NSC for T1 on the LM5027 Evaluation Board,
and is described in Application Note AN-1976.
1500 Vdc isolation, primary and auxiliary to secondaries
Auxiliary winding provides 10 V to power the chipset.
3. DCR for the primary is measured from pin 2 to pin 4. DCR for the
secondary is for each winding.
4. Leakage inductance is for the full primary and is measured with the
secondary shorted.
5. Output is with the secondary windings connected in series. Bias
winding output is 10 V, 65 mA.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
Pins 7 and 9 to be connected on
the PC board. Pin 3 is internally
connected only and does not
touch the PC board.
