Operating temperature range: -40C to +85C. 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. E & E Magnetic Products Ltd. DRAWING NO./MODEL 8. Output of the secondary is with the windings connected in parallel. Bias winding output is 12V, 20mA. REV 835-00848 SCALE DO NOT SCALE PAGE 01 3 OF 4
