2. Inductance is tested at 0.1Vrms, 100kHz .
3. The maximum current rating is based upon temperature rise of the DC current which will cause a typical
temperature rise of 40°C with no airflow when both one turn windings connected in parallel.
4. Terminating resistance (RT) value is based on 1 Volt output with 10 Amps flowing through the primary. Varying
terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
RT (Ohms) = Vout x Nsec / Iin.
5. Maximum volt-time product for the secondary.
6. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the
operating temperature under worst case operating conditions. Circuit design, component placement, PWB
trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature
should be verified in the end application.
