Notes:

1. The ET Max is calculated to limit the core loss and temperature rise at 100KHz based on a

bipolar flux swing of 180mT Peak.

2. For Push-Pull topology, where the voltage is applied across half the primary winding

turns, the ET needs to be derated by 50% for the same flux swing.

3. The applied ET may need to be further derated for higher frequencies based on the

temperature rise which results from the core and copper losses

A. To calculate total copper loss (W), use the following formula:

B. To calculate total core loss (W), use the following formula:

Where ET is the applied Volt Second, ET Max is the rated Volt Second for 180mT flux

swing

C. To calculate temperature rise, use the following formula: Temperature Rise (°C) =

90 * (Core Loss(W) + Copper Loss (W))

4. The AEC-Q200 temperature and humidity operational life testing was completed using a

dielectric strength test of 5000Vdc.

5. Optional Tape & Reel packing can be ordered by adding a “

T” suffix to the part number

(i.e. PH9185.012NL becomes PH9185.012NL

T). Pulse complies to industry standard tape and

reel specification EIA481.

6. The “NL” suffix indicates an RoHS-compliant part number.

7. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias

voltage applied between primary and secondary windings.

8. The PM2190.XXXNL part numbers are AEC-Q200 and IATF16949 certified.
