The Bel SRPE-12E1A0 is part of the non-isolated DC/DC converter
power module series. The modules use a SMD package. These
converters are available in a range of output voltages from 0.6 VDC to
5.5 VDC over a wide range of input voltage (Vin = 5.5 - 13.2 VDC). The
efficiency is typically 93% at 3.3 Vout (Vin = 12 Vdc) at full load.

The SRPE-12E1A0 modules are designed to be compatible with a reflow soldering process. The suggested Pb-free solder paste is
Sn/Ag/Cu(SAC). The recommended reflow profile using Sn/Ag/Cu solder is shown in the following. Recommended reflow peak
temperature is 245˚C while the part can withstand peak temperature of 260˚C maximum for 10 seconds. This profile should be used
only as a guideline. Many other factors influence the success of SMT reflow soldering. Since your production environment may
differ, please thoroughly review these guidelines with your process engineers.
Figure 25. Soldering information
The SRPE-12E1A0 modules have a MSL rating of 3.
The SRPE-12E1A0 modules are designed to be compatible with J-STD-033 Rev: A (Handling, Packing, Shipping and Use of Moisture
/Reflow Sensitive surface Mount devices). Moisture barrier bags (MBB) with desiccant are applied. The recommended storage
environment and handling procedure is detailed in J-STD-033.
This component has been designed, handled, and packaged ready for Pb-free reflow soldering. If the assembly shop follows J-
STD-033 guidelines, no pre-bake of this component is required before being reflowed to a PCB. However, if the J-STD-033
guidelines are not followed by the assembler, Bel recommends that the modules should be pre-baked @ 120~125˚C for a minimum
of 4 hours (preferably 24 hours) before reflow soldering.
