X2C027120FA1H-HV from HELE(Harmony Elec), in a SMD2016-4P. 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 | Crystal terminal 1 of the 27.120 MHz fundamental crystal (CL 10.0 pF, ESR 80 ohms max, drive level 10 uW typical and 100 uW max), connected to the crystal blank in the top-view drawing. |
| 2 | NC | unconnected | Corner pad with no internal crystal connection shown in the top-view drawing; the datasheet does not state its function, so treat it as a no-connect pad that is soldered to the land for mechanical support. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 27.120 MHz fundamental crystal (CL 10.0 pF, ESR 80 ohms max, drive level 10 uW typical and 100 uW max), connected to the crystal blank in the top-view drawing. |
| 4 | NC | unconnected | Corner pad with no internal crystal connection shown in the top-view drawing; the datasheet does not state its function, so treat it as a no-connect pad that is soldered to the land for mechanical support. |
