SWXJ8BCVE0-30.400000 from Starwave(思大), in a HC-49S-SMD. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XTAL1 | passive | First crystal terminal of the two-pad SMD HC-49S package (left pad in the drawing); the crystal is non-polarized, 3.2~90 MHz, 18 pF load capacitance or as specified. |
| 2 | XTAL2 | passive | Second crystal terminal of the two-pad SMD HC-49S package (right pad in the drawing); the crystal is non-polarized, drive level 1~500 µW (100 µW typical). |
