**JWT** · Crystals · SMD2520-4P

CM4024M00012T8188029 from JWT, 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 on the 2.5 x 2.0 x 0.55 mm ceramic SMD package; the crystal connection diagram shows it as one of the two crystal terminals, with 1 and 2 on the bottom edge. |
| 2 | XTAL2 | passive | Crystal terminal 2 on the 2.5 x 2.0 x 0.55 mm ceramic SMD package; the crystal connection diagram shows it as the other crystal terminal and marks it GND. |
| 3 | NC | unconnected | Pad 3 is a mechanical pad with no crystal connection shown in the Top View Crystal Connection diagram. |
| 4 | GND | power_in | Pad 4 is labelled GND in the Top View Crystal Connection diagram. |
