ECS-120-10-36Q-ES-TR

ECS · Crystals · SMD2520-4P

ECS-120-10-36Q-ES-TR from ECS, 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 In/Out passive Crystal terminal labeled In/Out in the Pad Connections table; pads 1 and 3 are interchangeable because the crystal is symmetrical.
2 Gnd power_in Ground pad listed as Gnd in the Pad Connections table; the datasheet gives no further electrical limits for this pad.
3 Out/In passive Crystal terminal labeled Out/In in the Pad Connections table; pads 1 and 3 are interchangeable because the crystal is symmetrical.
4 Gnd power_in Ground pad listed as Gnd in the Pad Connections table; the datasheet gives no further electrical limits for this pad.
