**HELE Harmony Elec** · Crystals · SMD2520-4P

X2B024000BC1HA-V 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 | Crystal | passive | Crystal terminal of the 24.000000 MHz quartz resonator; the datasheet labels this pin only as 'Crystal' and gives no separate electrical limit for it. |
| 2 | GND | power_in | Ground connection to the metal cover (GND/Lid), which the datasheet identifies as connected to the cover; no electrical limit is stated for this pin. |
| 3 | Crystal | passive | Crystal terminal of the 24.000000 MHz quartz resonator, paired with pin 1; the datasheet labels it only as 'Crystal' with no separate electrical limit. |
| 4 | GND/Lid | power_in | Ground connection to the metal lid/cover (GND/Lid), which the datasheet identifies as connected to the cover; no electrical limit is stated for this pin. |
