Description
The Bel xRAH-01Kxxx is a part of the low cost non-isolated dc/dc converter Power Module series. The modules
use a SMD or SIP package for ease of layout and space savings. The output is closely regulated and the
efficiency of 9 Vdc output module is typically 86% 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. Use "0" to replace "x" in the above part number to indicate Active High, and "L" to indicate Active Low.
3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
