Description
The Bel xRAH-03Hxx0 is part of the low cost non-isolated dc/dc power converter series. It is packaged in a
compact, overmolded package rated at 3 A. Optional lead forming provides a vertical mount product for minimal
footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency of 3.3
Vdc output is typically 90% at full load. Typical features include remote on/off, input under voltage lockout, over
current protection and short circuit protection.

Notes:
1. Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel
Packaging”, and “G” for “Tray Packaging”.
2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.

Notes: 1. The max Turn on Voltage threshold of the 3.3 V & 5.0 V output module will be relaxed to 4.9 V & 8.0 V
respectively.
2. The max Turn off Voltage threshold of the 3.3 V output module will be relaxed to 4.5 V. The 5.0 V output
module does not have such function.
