RL160001781 from TROQ, 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 | XTAL1 | passive | Crystal terminal 1 (pad 1 in the 3.2x2.5x0.7 mm 4-pad drawing); the internal-connection sketch ties it to the crystal element for 8.000 MHz to 54.000 MHz fundamental operation. |
| 2 | NC/GND | passive | Pad 2 in the 4-pad drawing; the datasheet's internal-connection sketch does not clearly show a crystal connection, so function is not stated. |
| 3 | XTAL2 | passive | Crystal terminal 2 (pad 3 in the 3.2x2.5x0.7 mm 4-pad drawing); the internal-connection sketch ties it to the crystal element, diagonal to pad 1. |
| 4 | NC/GND | passive | Pad 4 in the 4-pad drawing; the datasheet's internal-connection sketch does not clearly show a crystal connection, so function is not stated. |
