# 0132M4-10.240F12DZNG

**HCI (Suzhou HangJing Elec and Tech)** · Quartz crystal, 10.24 MHz · SMD 3225, 4 pads

HCI 0132M4 series AT-cut fundamental quartz crystal in a 3.2 x 2.5 mm seam-sealed ceramic package, ordered at 10.240 MHz with a 12 pF load. A passive crystal unit (not an oscillator): it needs an external oscillator circuit.

## Verification

A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Crystal. |
| 2 | G | passive | Ground (lid). |
| 3 | 3 | passive | Crystal. |
| 4 | G | passive | Ground (lid). |

**Note:** pads 2 and 4 are both ground (the metal lid). The symbol has one G pin numbered `[2,4]`, KiCad's stacked-pin notation, so wiring that pin connects both pads; the Fusion library connects G to pads "2 4" and the Altium library stacks pins 2 and 4.

**Note:** The one-page datasheet gives the pad layout as a drawing; the crystal-on-1-and-3 assignment is the standard 3225 four-pad layout and matches the KiCad footprint.
