SL252024M20P 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 (chamfered pad, marked-dot corner) connected to one side of the 24.000 MHz AT-cut resonator, load capacitance 20 pF. |
| 2 | NC | unconnected | Land pad with no resonator connection shown in the terminal land connection drawing; used for mechanical support. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the 24.000 MHz resonator, diagonally opposite pin 1. |
| 4 | NC | unconnected | Land pad with no resonator connection shown in the terminal land connection drawing; used for mechanical support. |
