PQ60280FTA26 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
temperature with appropriate power derating. Specifications subject to change without notice.
Note 1: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 2: There is no derating with a baseplate temperature of 100C or lower.
Note 3: Higher values of isolation capacitance can be added external to the module.
