SJK(SHENZHEN CRYSTAL TECH) · Crystals · SMD3225-4P
7U12000E12UCG from SJK(SHENZHEN CRYSTAL TECH), 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, connected to one side of the quartz resonator (pad 1 is the chamfered pad) with 12.0 pF load capacitance specified. |
| 2 | GND | power_in | Marked GND in the crystal connection drawing; this pad is tied to ground (lid/case). |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the quartz resonator, with 12.0 pF load capacitance specified. |
| 4 | GND | power_in | Marked GND in the crystal connection drawing; this pad is tied to ground (lid/case). |
