Frequently Asked Questions
Which high-voltage input rails can use R-78HB3.3-0.5?
R-78HB3.3-0.5 accepts a 9 V to 72 V input range, so it can regulate from nominal 48 V buses and other industrial DC supplies down to 3.3 V.
How much 3.3 V load current is this RECOM module intended to supply?
The module provides a regulated 3.3 V output at up to 0.5 A, which fits microcontrollers, interface logic, sensors, and modest point-of-load power rails.
What mechanical format should designers reserve on the PCB?
This part is supplied as a SIP3 module with 3 pins, so layout teams should use the proper through-hole footprint and allow clearance for a vertical regulator body.
