JWT · Crystals · SMD3225-4P
CF4012M00012T5074049 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 (pin-1 notched pad), connected to one side of the 12.000 MHz AT-cut resonator with CL 12 pF. |
| 2 | GND | power_in | Connected to ground (GND) per the Top View Crystal Connection drawing; not connected to the resonator. |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the 12.000 MHz AT-cut resonator with CL 12 pF. |
| 4 | GND | power_in | Connected to ground (GND) per the Top View Crystal Connection drawing; not connected to the resonator. |
