**Hosonic Elec** · Crystals · SMD2520-4P

E2SB26E00000DE from Hosonic 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 connected to one side of the resonator in the top-view drawing (pad 1, marked with the chamfered corner); fundamental mode, 12 to 62.5MHz, load capacitance 8 to 16pF. |
| 2 | NC | unconnected | Corner pad with no internal connection to the resonator in the top-view drawing; the datasheet states no function for it. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator in the top-view drawing; fundamental mode, 12 to 62.5MHz, load capacitance 8 to 16pF. |
| 4 | NC | unconnected | Corner pad with no internal connection to the resonator in the top-view drawing; the datasheet states no function for it. |
