Notes
  1. When ordering, please specify packaging code: e.g.CST7030-150LC
  2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
  3. Maximum volt-time product is for the secondary, based on 2000 Gauss.
  4. Primary current of 20 A causes less than 25°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
  5. Terminating resistance (RT) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT (Ohms) = Vout × Nsec / Iin.
  6. 500 Vrms, 1 minute isolation (hipot) winding to winding.

Termination:

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

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (600 parts per full reel).
  • B = Less than full reel
    To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel).
