Hinweise
  1. When ordering, please specify packaging code: e.g. POE13P-12LD
  2. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DCR for the secondary is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance is measured between pins 3 and 4 with all other pins shorted.
  5. Turns ratio is with the secondary windings connected in parallel.
  6. 1500 Vrms, 1 minute isolation (hipot) from primary and bias to secondary.
    500 Vrms, 1 minute isolation between all other windings.

Anschlüsse:

  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

Verpackung:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape
