  1. When ordering, please specify termination and screening codes: e.g. ST614TCB1200LZ.
  2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
  3. Volt-time product is for the secondary, between pin 4 and 5.
  4. For specific questions regarding frequency range, please contact us at [email protected].
  5. Primary current of 28 A causes less than 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
  6. Terminating resistance (RT) value is based on 1 Volt output with 28 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec/Iin.
