The ET Max is calculated to limit the core loss and temperature rise at 100KHz based on a C. To calculate temperature rise, use the following formula: Temperature Rise (C) = bipolar flux swing of 180mT Peak. 90 * (Core Loss(W) + Copper Loss (W)) 2.

The applied ET may need to be further derated for higher frequencies based on the 5. Optional Tape & Reel packing can be ordered by adding a T suffix to the part number temperature rise which results from the core and copper losses (i.e. PH9185.012NL becomes PH9185.012NLT).

Intended to operate in a fixed duty cycle Push Pull topology, it is a part of a low cost solution for delivering lower power (up to 3W) from a low voltage source. A typical implementation would be an isolated RS-485/RS-232 power supply driver circuit, the design is compatible with the MAXIM MAX253 IC. A schematic diagram for the Push Pull converter topology is given below. VIN PH9185/PM2190 VCC D1 VOUT DRIVER IC D2 GND For a fixed 50% duty cycle mode of operation, the output voltage is simply determined by the input voltage and turns ratio. So, with the available turns ratios, a variety of output voltages can be selected. nd nd This transformer design has been certified by UL to comply with UL60950-1 2 edition, and CAN/CSA C22.2 NO. 60950-1-07 2 edition and by TUV to comply with EN61558-1 and EN61558-2-16 with reinforced insulation for a working voltage up to 400Vac 8mm creepage and 5000Vrms isolation voltage is guaranteed to meet this requirement. The design also complies with the Pulses class F insulation system. PH9185.013NL was not included in the original UL/TUV certification but is complaint.
