SWXJHBCVE0-27.120000 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 3rd-overtone 27.12 MHz unit (XJ series, 18 pF load capacitance or as specified, 1~500 µW drive level, 100 µW typical), non-polar and interchangeable with the other terminal. |
| 2 | XTAL2 | passive | Second crystal terminal of the 3rd-overtone 27.12 MHz unit (XJ series, 100 Ω max ESR for 27~30 MHz, 7 pF max shunt capacitance), non-polar and interchangeable with the other terminal. |
