The xRSB-40U series are isolated dc/dc converters that operate from
a nominal 24 Vdc or 48 Vdc source. These units will provide up to 40
W of output power from an 18 Vdc - 75 Vdc wide input range. These
units are designed to be highly efficient and low cost. Features
include remote on/off, over current protection and under voltage
lockout. These converters are provided in an industry standard
sixteenth brick package.

The xRSB-40Uxxx modules are designed to be compatible with 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℃ while the part can withstand peak temperature of 260℃ maximum for 10seconds. 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.
The xRSB-40Uxxx modules have a MSL rating of 3.
The xRSB-40Uxxx 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. Our packaging tray can only
withstand temperature of 70° C max.

Note: 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 245 C.
