注释
  1. When ordering, please specify a packaging code: GA3291-ALD. 
  2. Inductance is measured at 300 kHz, 0.6 Vrms, 0 Adc.
  3. DCR for the primary is measured from pin 1 to pin 3.
  4. Leakage inductance is for the primary (pin 1 to pin 3) and is measured with the secondary shorted.
  5. Turns ratio is based on the entire the primary winding (pin 1 to pin 3).
  6. 1500 Vrms isolation from primary to secondary.

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.
