**HCI** · Crystals · SMD2016-4P

0121M424000F12HPNN from HCI, 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; connects to one side of the quartz crystal unit (load capacitance 6 to 32pF or series, drive level 100µW max). |
| 2 | N.C._or_GND | passive | Connected to the metal lid; may be left open (floating) or connected to ground. |
| 3 | CRYSTAL | passive | Crystal terminal; connects to the other side of the quartz crystal unit (load capacitance 6 to 32pF or series, drive level 100µW max). |
| 4 | N.C._or_GND | passive | Connected to the metal lid; may be left open (floating) or connected to ground. |
