HD · Crystals · SMD3225-4P
7B027000R01 from HD, in a SMD3225-4P. 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 one side of the 27MHz quartz resonator (pin 1 marked by the corner chamfer pad). |
| 2 | GND | power_in | Ground pad, connected to GND per the internal view connection (typically to the lid). |
| 3 | CRYSTAL | passive | Crystal terminal connected to the other side of the 27MHz quartz resonator. |
| 4 | GND | power_in | Ground pad, connected to GND per the internal view connection (typically to the lid). |
