HELE(Harmony Elec) · Crystals · SMD2520-4P
X2B02863ADC1H-W from HELE(Harmony Elec), 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 (28.63636MHz fundamental, CL 12.0 pF, ESR 80 ohms max, drive level 10 uW typ and 100 uW max), shown in the top-view drawing as connected to one side of the quartz blank. |
| 2 | NC | unconnected | Corner pad that the top-view drawing shows with no connection to the quartz blank, so it is treated as a no-connect. |
| 3 | XTAL2 | passive | Crystal terminal 2 (28.63636MHz fundamental, CL 12.0 pF, ESR 80 ohms max, drive level 10 uW typ and 100 uW max), shown in the top-view drawing as connected to the opposite side of the quartz blank. |
| 4 | NC | unconnected | Corner pad that the top-view drawing shows with no connection to the quartz blank, so it is treated as a no-connect. |
