**Abracon LLC** · Crystals · SMD2016-4P

ABM11-40.000MHZ-B1U-T3 from Abracon LLC, 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 | XTAL1 | passive | Crystal terminal connected to one side of the quartz element (top view, bottom-left); the part may be built with the chamfer on pin 1 or 4 with no electrical effect. |
| 2 | GND | power_in | Ground pad, marked GND in the top-view drawing (bottom-right), connected to the metal lid/case. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the quartz element (top view, top-right). |
| 4 | GND | power_in | Ground pad, marked GND in the top-view drawing (top-left); the part may be built with the chamfer on pin 1 or 4 with no electrical effect. |
