TROQ · Crystals · SMD2520-4P
RQ27000318 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 | 1 | passive | Crystal terminal pad 1 of the 2.5x2.0x0.55 mm 4-pad SMD package, 12.000MHz to 54.000MHz fundamental mode. |
| 2 | 2 | passive | Pad 2 of the 4-pad SMD package; the drawing shows it but gives no function, so it is probably a case or no-connect pad. |
| 3 | 3 | passive | Crystal terminal pad 3 of the 4-pad SMD package, the opposite terminal to pad 1 in the usual two-terminal arrangement. |
| 4 | 4 | passive | Pad 4 of the 4-pad SMD package; the drawing shows it but gives no function, so it is probably a case or no-connect pad. |
