メモ
  1. Output of the secondary is with the windings connected in parallel. Aux winding output is 2.5 V, 20 mA.
  2. When ordering, please specify packaging code: e.g. MA5237-ELD
  3. Inductance is for the primary, measured at 500 kHz, 0.1 Vrms.
  4. Peak primary current drawn at minimum input voltage.
  5. DCR for the secondary is measured with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Leakage inductance is for the primary winding with the secondary windings shorted.
  7. Turns ratios are with the secondary windings connected in parallel. 
  8. 3500 Vrms, one minute isolation primary to secondary windings.

終端処理:

  • RoHS-compliant. 260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

パッケージ:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (200 parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
