B0503S-1WR3
by DEXU(德旭电子)
The B0503S-1WR3 from DEXU is an isolated DC-DC power module used to supply circuitry across a power isolation boundary. Its through-hole construction makes the module a discrete board-mounted component in the power stage. The download provides a four-pin symbol alongside the four-pad PWRM-TH_B0503S-1WR2 footprint and an included 3D model. Note that the supplied footprint identifier ends in 1WR2 while the listed part number ends in 1WR3; that identifier is preserved in the KiCad files. A real ProtoFlow import supplied the files, and the converted result was checked in the editor. The complete part can be opened directly in ProtoFlow.
