**TOGNJING** · Crystals · SMD2520-4P

XTM25016000DT00351001 from TOGNJING, 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 | Crystal_1 | passive | Crystal terminal (pin #1, connected as Crystal per the pin table); the part is a 12-100 MHz AT-fundamental resonator with 6-20 pF load capacitance options. |
| 2 | GND | power_in | Ground pin (#2 connects to GND per the pin table), typically tied to the lid/case. |
| 3 | Crystal_2 | passive | Crystal terminal (pin #3, connected as Crystal per the pin table); drive level is 10-200 µW max (100 µW typical). |
| 4 | GND | power_in | Ground pin (#4 connects to GND per the pin table), typically tied to the lid/case. |
