Q48T20050 and Q48S20050  
Data Sheet  
36-75 Vdc Input, 20 A, 5.0 Vdc Output  
The Q48T20050 through-hole and Q48S20050 surface  
mounted DC/DC converters offer unprecedented perform-  
ance in the industry-standard quarter brick format. This is  
accomplished through the use of patent pending circuit and  
packaging techniques to achieve ultra-high efficiency, excel-  
lent thermal performance and a very low body profile.  
&&  
In telecommunications applications theQFamily 20 A con-  
verters provide thermal performance that exceeds competing  
quarter bricks with a higher nominal rating. Low body profile  
and the preclusion of heatsinks minimize airflow shadowing,  
thus enhancing cooling for downstream devices. The use of  
100% surface-mount technologies for assembly, coupled  
with di/dt’s advanced electric and thermal circuitry and pack-  
aging, results in a product with extremely high quality and  
reliability.
