Notes:
(1) Vin = 48Vdc, Ta = 25 °C, Airflow = 200 LFM for all data unless otherwise noted.
(2) Output ripple voltage and noise is specified when measured with a 10uF electrolytic and a 1uF ceramic capacitor at the converter
output pins.
(3) Transient response is specified without a capacitor at the output of the converter.
(4) Product operates with an external capacitance significantly greater than specified. However, for values higher than 2000uF please
contact Celestica representative.
(5) Thermal shutdown is monitored at the Thermal Measurement Location (TML). See ‘Mechanical Information’ on page 3 for TML
location.
(6) See ‘Safety Considerations’ shown on last page.
(7) De-rating curves are conducted in a controlled environment. End application testing is required to ensure the Thermal Measurement
Location temperature is below the maximum specified.
(8) Recommended airflow direction is from pin 1 to pin 3, or 3 to 1 (transverse airflow).
