SRPE-03E1A0G

The Bel SRPE-03E1A0 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 92% at 3.3 Vout (Vin = 12 VDC) at full load. • • • • • • • • • • • • 5.5 – 13.2 VDC Input 0.6 – 5.5 VDC / 3 A Output Non-Isolated Wide Output Trim Range Fixed Frequency High Efficiency OCP/SCP Wide Input Voltage Range Remote On/Off Low Cost Under-Voltage Lockout Class II, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592B) • • • Networking Computers and Peripherals Telecommunications SRPE-03E1A0 2 MODEL NUMBER SRPE-03E1A0G SRPE-03E1A0R S Mounting Type Surface Mount OUTPUT VOLTAGE INPUT VOLTAGE MAX.

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 22. Soldering temperature The SRPE-03E1A0 modules have a MSL rating of 3. The SRPE-03E1A0 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 JSTD-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℃ for a minimum of 4 hours (preferably 24 hours) before reflow soldering. tech.support@psbel.com SRPE-03E1A0 11 Figure 23.
