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.

RoHS Compliance
Complies with the European Directive 2002/95/EC, calling for the elimination of lead and
other hazardous substances from electronic products. These parts are not however
compatible with the higher temperatures associated with lead free solder processes and
must be soldered using a reflow profile with a peak temperature of no more than 240 ºC.
