注释
  1. Output of the seconday is with the windings connected in parallel.
  2. When ordering, please specify packaging code: HA3905-CLD.
  3. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
  4. Leakage inductance measured on the primary winding with all secondary pins shorted.
  5. 1500 Vrms,one minute isolation from primary, auxiliary and reset to secondary;
    500 Vrms, one minute isolation from primary and reset to auxiliary

端子:

  • 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.

包装:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
