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”.
With simulated source impedance of
500 nH, 5 Hz to 20 MHz; Use one 100
uF/25 V tantalum capacitor at the input.
Note:
All specifications are typical at 25°C unless otherwise stated.
