注释
  1. When ordering, please specify packaging code: e.g.TA7788-ALD
  2. Inductance is for the primary, measured on an Agilent/HP 4284 at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DC current that causes an inductance drop of 30% (typ) from its value without current
  4. DCR is measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Leakage inductance measured between pins 2 and 3 at 250 kHz, 0.1Vrms, 0 Adc with all secondary pins shorted.
  6. 5000 Vrms, one minute isolation (hipot), from primary to secondary.

端子:

  • RoHS-compliant. 260°C compatible. RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze.

包装:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (700 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.
