注释
  1. Sec1, Sec2, Sec3 outputs: 30 V, 0.15 A; Sec4 output: 30 V, 0.50 A.
  2. Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0 Adc.
  3. DC current that causes the primary inductance to drop 30% from its value without current.
  4. Leakage inductance is for the primary with the secondary windings shorted.
  5. 1500 Vrms, one minute isolation (hipot) between primary and secondary windings.

端子:

  • RoHS-compliant, halogen free. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronze terminations.

包装:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
