The SQE48T40018 Series is a 72 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 1.8 VDC at 40 A. Quarter-brick pinout compatibility enables direct replacement without PCB changes; output trim of -20% ~ +10% accommodates tight voltage tolerances on 1.8 V memory and logic rails. Suited for high-current 1.8 V rails in networking ASICs and server platforms.
