  1. To order a transformer with an optional auxiliary winding, add an “X” and the turn count after the PL300, e.g. PL300X3-100LB.
    Turn counts of 1, 2, 3, 4, 5, 7 and 9 are available for the auxiliary winding.
    Transformers with auxiliary windings are not stocked. Call for lead time.
  2. Inductance measured on an Agilent/HP 4284 at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5 with pins 3 and 4 connected.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. DCR for secondary is measured between pins 7 and 11.
  4. Leakage inductance measured at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5, with pins 3 and 4 connected, and with all secondary pins shorted
  5. Volt-time product is based on primary windings connected in series.
