Q48S30 Family
Q48S30 family surface-mount DC/DC converters offers unprecedented performance industry-standard quarter brick format. This accomplished through patent pending circuit packaging techniques achieve ultra-high efficiency, excellent thermal performance very body profile.
telecommunications applications Series converters provide thermal performance that exceeds quarter bricks comparable even existing halfbricks. Very profile preclusion heatsinks minimize airflow shadowing, thus enhancing cooling downstream devices. 100% surface-mount technologies assembly, coupled with di/dt's advanced electric thermal circuitry packaging, result products with extremely high quality reliability.
