The SQE48T20033 Series is a 66 W DC-DC converter in a through-hole eighth-brick measuring 62% of the standard quarter-brick footprint, accepting 36 ~ 75 VDC and delivering a regulated 3.3 VDC at 20 A with 2250 VDC input-to-output isolation. Quarter-brick pinout compatibility enables direct replacement without PCB revisions, freeing nearly 40% of the original converter footprint for signal routing or additional components in dense telecom line card designs.
