X49SM12MSD2SC
by YXC(扬兴晶振)
The HC-49S package identifies the physical format of YXC's X49SM12MSD2SC quartz crystal. Used as the resonant element in oscillator circuits, this two-terminal component supports timing and clock-reference functions. The record lists SMD mounting, and the free KiCad download includes a 2-pin schematic symbol plus the 2-pad HC-49S_L11.4-W4.8 footprint. A 3D model is supplied as well, so package placement can be viewed with the surrounding board components. For this part, 2 ProtoFlow engineers have used the conversion in real designs. To work with the crystal's library files, open it directly in ProtoFlow.
