メモ
  1. Output is with the secondary windings connected in parallel. Output of the auxiliary winding is 12 V
  2. When ordering, please specify packaging code: e.g. CX9642-ALD
  3. Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
  4. DCR is with the windings connected in parallel.
  5. Leakage inductance is for the primary winding with the secondary windings shorted.
  6. Turns ratio is with the primary and the secondary windings connected in parallel.
  7. Isolation: 1500 Vrms one minute primary and auxiliary to secondary; 500 Vrms primary to auxiliary.

終端処理:

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

パッケージ:

  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape (175 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.
