Notes:

1. 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

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 PH9084.011NLT). Pulse complies to industry standard tape

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

Copper Loss (W) = Irms_Primary²* DCR_Primary + Irms_Secondary²*DCR_Secondary and reel speciﬁcation EIA481.

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

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