 
Planar Transformer
For Maxim MAX5069A
| 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.)
|
- Developed for Maxim MAX5069A PWM Controller
- For push-pull, half-bridge and full-bridge topologies
- Ideal for use in high-current power supply applications
- 1500 Vrms isolation - primary to secondary windings
- RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.
- Designed using Coilcraft Planar Prototyping Kit C356.

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. |

Inductance measured
on an Agilent/HP 4284 between pins 2 and 4 at 250 kHz, 0.1 Vrms, 0 Adc |
| 3 |
Leakage
inductance measure between pins 2 and 4 at 250 kHz, 0.1 Vrms, 0 Adc with
pins 6, 8 and 10 shorted. |
