Q48T08120 DC-DC Converter Data Sheet
36-75 VDC Input; 12VDC @ 8A Output
The
Q48T08120
through-hole mounted DC/DC converter
offers unprecedented performance 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, excellent thermal performance and a
very low body profile.
&&
In telecommunications applications the
Q
Family
8 A con-
verters provide excellent thermal performance. Low body
profile and the preclusion of heat sinks minimize airflow
shadowing, thus enhancing cooling for downstream devices.
The use of 100% surface-mount technologies for assembly,
coupled with Power-One’s advanced electric and thermal
circuitry and packaging, results in a product with extremely
high quality and reliability.
