RQ12000354 from TROQ, in a SMD2520-4P. 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 (pin-1 index corner) of the 12.000000 MHz fundamental-mode crystal, load capacitance 12 pF, connected to one side of the crystal element. |
| 2 | GND | power_in | Connected to ground (lid/case) according to the connection diagram. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 12.000000 MHz fundamental-mode crystal, connected to the other side of the crystal element. |
| 4 | GND | power_in | Connected to ground (lid/case) according to the connection diagram. |
