X2B026000B91H-HZ from HELE Harmony 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 (chamfered index pad), connected to one electrode of the 26.000MHz fundamental-mode blank, CL 9.0pF, ESR 60 ohms max, drive level 100uW max. |
| 2 | NC | unconnected | Corner pad with no internal connection to the crystal blank shown in the drawing; used for mechanical soldering to the land pattern. |
| 3 | XTAL2 | passive | Crystal terminal, connected to the second electrode of the 26.000MHz fundamental-mode blank, CL 9.0pF, ESR 60 ohms max, drive level 100uW max. |
| 4 | NC | unconnected | Corner pad with no internal connection to the crystal blank shown in the drawing; used for mechanical soldering to the land pattern. |
