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

E2SB50E00000EE 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, drawn in the top-view schematic as wired to the crystal element and marked by the chamfered pad; the datasheet gives no signal name. |
| 2 | NC | unconnected | Pad with no connection to the crystal element in the top-view drawing; the datasheet gives no function for it. |
| 3 | XTAL2 | passive | Second crystal terminal, drawn in the top-view schematic as wired to the crystal element; the datasheet gives no signal name. |
| 4 | NC | unconnected | Pad with no connection to the crystal element in the top-view drawing; the datasheet gives no function for it. |
