Planar Magnetics
for
NSC LM5041
| 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. (View old data sheet.) |
- Specially developed for use with the National Semiconductor LM5041 Cascaded PWM Controller
- Low profile, high efficiency planar transformer
- Planar output choke inductor
- RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations

| 1 | When ordering, please specify packaging code: e.g. A9786-ALD | |
| Packaging: | D =
13"
machine-ready reel EIA RS-481 clear plastic tape (125 parts per full reel). B = Less than full reel In tape, 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 3 at 250 kHz, 0.1 Vrms, 0 Adc. | |
| 3 | Leakage inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted. | |
| 4 | Primary/secondary isolation 1100 Vdc. | |
| 5 | Ambient temperature range: | –40°C to +85°C |
| 6 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°C to +80°C |
| 7 | 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. | |
| 8 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
