National Semiconductor LM5025 & LM5034
| New RoHS part numbers are shown.
Lead was removed from internal parts. The next to the last character is
an L to indicate
RoHS compliance.

When ordering, please
specify packaging code: e.g. B0357-BLD |
|
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 measured on an Agilent/HP 4284 between pins 1 and 2 at 250 kHz,
0.1 Vrms, 0 Adc. |
| 3 |
Leakage inductance measured between pins 1 and 2 at 100 kHz, 0.1 Vrms, 0 Adc
with secondary pins shorted. |
| 4 |
Ambient temperature range: |
–40°C to +85°C |
| 5 |
Storage temperature range: |
Component: –40°C to +85°C
Packaging: –55°C to +80°C |
| 6 |
Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. |
| 7 |
Electrical specifications at 25°C. |
