PQ60012QTA40 ELECTRICAL CHARACTERISTICS
TA=25°C, airflow rate=300 LFM, Vin=48Vdc unless otherwise noted; full operating temperature range is -40°C to +100°C ambient tem-
perature with appropriate power derating. Specifications subject to change without notice.
Note 1: Output voltage ripple can exceed maximum specification during startup when output voltage is less than 0.5V and current is simultaneously greater than 5A. Additional
output capacitance will mitigate this startup ripple behavior. For applications requiring reduced output voltage ripple and noise, consult SynQor applications support
(e-mail: support@synqor.com)
Note 2: Higher values of isolation capacitance can be added external to the module.
