ECS-250-10-37Q-ES-TR

ECS · Pre-ordered Products · SMD2016-4P

ECS-250-10-37Q-ES-TR from ECS, in a SMD2016-4P. 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 In/Out passive Crystal terminal (In/Out) of the 4-pad SMD crystal; the datasheet states pads 1 and 3 are interchangeable because the crystal is symmetrical.
2 Gnd power_in Ground pad connection for the crystal package.
3 Out/In passive Crystal terminal (Out/In) of the 4-pad SMD crystal; the datasheet states pads 1 and 3 are interchangeable because the crystal is symmetrical.
4 Gnd power_in Ground pad connection for the crystal package.
