Notes:

1. Inductance is measured at 200kHz, 0.1rms, 0Adc.

2. Operating temperature range: -40°C to +125°C. 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.

3. Turns ratio is with the secondary windings connected in parallel.

4. Output of the secondary is with the windings connected in parallel.
