  1. When ordering, please specify packaging code: e.g. PTRF4000LD
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance shown for each winding, measured at 130 kHz.
  4. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Interwinding isolation (hipot) tested for one minute.
