Q48S08120-PS00G

The Q48S08120 surface 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 converters 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 advanced electric and thermal circuitry and packaging, results in a product with extremely high quality and reliability.
