1. The maximum volt-usec rating limits the peak flux density to 3600 gauss when
used in bi-polar drive application with 200KHz. For unipolar drive applications or a
bi-polar drive with 350kHz, a maximum volt-usec could be 60% of the listed value.
For Push-Pull topology, where the voltage is applied across half the primary wind-
ing turns, the maximum volts-use needs to be derated by 50%.
2. The AEC-Q200 temperature and humidity operational life testing was completed
using a dielectric strength test of 5000Vdc.
3. Optional Tape & Reel packing can be ordered by adding a “T” sux to the part
number (i.e. PH9185.012NL becomes PH9185.012NLT). Pulse complies to industry
standard tape and reel specification EIA481.
4. The “NL” sux indicates an RoHS-compliant part number.
5. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the
bias voltage applied between primary and secondary windings.
