X3S024000BA1H-U

HELE(Harmony Elec) · Crystals · SMD3225-4P

X3S024000BA1H-U from HELE(Harmony Elec), in a SMD3225-4P. 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 #1 passive Crystal terminal pad #1 (chamfered pad marking pin 1) of the 24.000MHz fundamental-mode crystal, 10pF load capacitance, 60 ohms max series resistance.
2 #2 passive Pad #2 of the HSX321S 4-pad package; the datasheet does not state its electrical function (assumed non-signal pad, see review).
3 #3 passive Crystal terminal pad #3, diagonally opposite pad #1, the second terminal of the 24.000MHz crystal.
4 #4 passive Pad #4 of the HSX321S 4-pad package; the datasheet does not state its electrical function (assumed non-signal pad, see review).
