JWT · Crystals · SMD3225-4P
CF4040M00015 from JWT, in a SMD3225-4P. 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 (marked pad with chamfer); the crystal symbol in the connection view connects pin 1 to pin 3, 40.000MHz, CL 15pF. |
| 2 | GND | power_in | Pad labelled GND in the connection view, with no crystal connection shown and likely tied to the lid; GND is printed beside pin 2. |
| 3 | XTAL2 | passive | Crystal terminal 2, diagonal to pin 1; the connection view also prints a GND label beside pin 3. |
| 4 | GND | power_in | Pad not wired to the crystal in the connection view, likely tied to the lid and GND; no label is printed on this pad. |
