The ET Max is calculated to limit the core loss and temperature rise at 200KHz 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: - Copper Loss (W) = Irms_Primary[2] * DCR_Primary + Irms_Secondary[2] *DCR_Secondary - B. To calculate total core loss (W), use the following formula: - Core Loss (W) = 1.2E-12 * (Frequency in kHz)[1.9] * (180 * [ET/ET Max])[2.7] - 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) = 302 * (Core Loss(W) + Copper Loss (W)) 4. Optional Tape & Reel packing can be ordered by adding a “ **T** ” suffix to the part number (i.e. PH9084.011NL becomes PH9084.011NL **T** ). Pulse complies to industry standard tape and reel specification EIA481. 5. The “NL” suffix indicates an RoHS-compliant part number. ## **Mechanical** ## **Schematic** **==> picture [541 x 285] intentionally omitted <==** **----- Start of picture text -----**<br> PH9084.XXXNL<br>_“_y_|||.”.)DLCOCUCOCOOOOOOO°&7© © °°<br>1 6<br>2 5<br>3 4<br>PRIMARY SECONDARY<br>Weight ...........................0.37grams<br>Tape & Reel ........................900/reel<br>Tray ......................................120/tray<br>Dimensions: mm<br>|<br>Unless otherwise specified,<br>. - all tolerances are ±0.25<br>| . a | |<br>1 power.pulseelectronics.com P781.
