Hosonic Elec · Crystals · SMD2520-4P
E2SB28E0X0005E 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 the quartz blank (X'tal), paired with pin 3 for the 28.636360 MHz fundamental-mode resonator with 10 pF load capacitance. |
| 2 | GND | power_in | Ground connection, tied to the lid/case per the pin connection table (#2 and #4 are GND). |
| 3 | XTAL2 | passive | Crystal terminal connected to the quartz blank (X'tal), paired with pin 1 for the 28.636360 MHz fundamental-mode resonator with 10 pF load capacitance. |
| 4 | GND | power_in | Ground connection, tied to the lid/case per the pin connection table (#2 and #4 are GND). |
