7. Operating temperature: -40°C to +85°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.
8. The transformer is designed to meet operational insulation.
9. This part is closely similar to 835-00900F but the number of turns for 5V winding has been
increased to 12 turns and LL is reduced to 1.0uH typical to meet the specific requirements of
Cisco Bananarama program.
