E2SB37E0X0004E

Hosonic Elec · Crystals · SMD2520-4P

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.
