Q48T30033-NBBO
The Q48T30033 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
verters provide thermal performance that far exceeds all
quarter bricks and is comparable even to existing half-bricks.
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 ex-
tremely high quality and reliability.
