Description
The Bel xRAH-01FxxN modules are non-isolated; step down dc/dc converters that operate from a 3 V - 5.5 V
source. Output voltages are -5.0 V, -5.2 V, and -12 V. They are packaged in a compact, overmolded package
rated at 1 A, 1 A, 0.5 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 is typically 88% at 1 A, -5 V
output at full load.

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.
