E2SB37E0X0004E 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 (#1,#3 are X'tal connections) for the 37.400000MHz fundamental-mode crystal with 12pF load capacitance; pin 1 is marked by the logo location. |
| 2 | GND | power_in | Ground connection (#2,#4 are GND) to the lid/case of the 2520 seam-sealed crystal. |
| 3 | XTAL2 | passive | Crystal terminal (#1,#3 are X'tal connections) for the 37.400000MHz fundamental-mode crystal with 12pF load capacitance. |
| 4 | GND | power_in | Ground connection (#2,#4 are GND) to the lid/case of the 2520 seam-sealed crystal. |
