**HD** · Crystals · SMD2016-4P

7D027000I01 from HD, 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 | CRYSTAL | passive | Crystal terminal connected to the resonator, diagonal to pin 3, for 27.000MHz fundamental mode operation with 10pF load capacitance. |
| 2 | GND | power_in | Ground pad connected to the package lid/ground per the internal view connection. |
| 3 | CRYSTAL | passive | Second crystal terminal connected to the resonator, diagonal to pin 1, for 27.000MHz fundamental mode operation with 10pF load capacitance. |
| 4 | GND | power_in | Ground pad connected to the package lid/ground per the internal view connection. |
