SL252040M15P from Slkor(SLKORMICRO Elec.), 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 connected to one side of the quartz element (chamfered pad-1 marker) in the terminal land connection drawing, 40.000 MHz AT-cut fundamental, CL 15 pF. |
| 2 | NC | unconnected | Terminal not connected to the crystal element in the terminal land connection drawing; no function is stated in the datasheet. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the quartz element in the terminal land connection drawing, 40.000 MHz AT-cut fundamental, CL 15 pF. |
| 4 | NC | unconnected | Terminal not connected to the crystal element in the terminal land connection drawing; no function is stated in the datasheet. |
