Use the 2-pad footprint on this page, which follows Kyocera's recommended land pattern.++## Key specifications++| Parameter | Value | Source |+|---|---|---|+| Nominal frequency | 8.000 MHz (code `08000`) | How to Order |+| Mode | Fundamental | Specifications |+| Load capacitance CL | 8.0 pF (code `D0`) | How to Order, Specifications |+| Frequency tolerance | +-50 ppm at 25 C +-3 C (code `P`) | How to Order, Specifications |+| Frequency vs temperature | +-150 ppm over -40 to +150 C, referred to 25 C (codes `T`, `V`) | How to Order, Specifications |+| ESR (motional series resistance) | 500 ohm max (8 <= F < 9.8 MHz) | Table 1 |+| Drive level | 10 uW typical, 200 uW max | Specifications |+| Shunt capacitance C0 | 3.0 pF max | Specifications |+| Operating and storage temperature | -40 to +150 C | Specifications |+| Qualification | AEC-Q200, PSL R4Y, MSL 1, RoHS compliant | Catalog header |+| Package | 3.2 +-0.1 x 2.5 +-0.1 x 0.85 +-0.1 mm, ceramic base with metal lid, 2 electrodes | Dimensions |+| Packaging | Tape and reel, 3000 pcs per reel | How to Order |+| Individual specification | `TT` (Kyocera's standard specification is `CC`; `TT` is an individual specification) | How to Order |++All values: Kyocera, Crystal Units Surface Mount Type CX3225GA, catalog page (As of October 2025), [PDF](docs/cx3225ga08000d0ptvtt-datasheet.pdf). The catalog also notes that frequencies from 12 MHz up are standard and asks buyers to contact Kyocera for 8 to 10 MHz; this 8 MHz part number is listed by Mouser and DigiKey.++**Design note.** With CL = 8 pF, the two load capacitors are about 2 x (8 pF minus the board's stray capacitance), typically 10 to 12 pF each for 2 to 3 pF of stray. At 500 ohm maximum ESR, check the oscillator's gain margin (negative resistance at least 3 to 5 times ESR, so about 1.5 to 2.5 kohm) against your MCU's crystal driver, and keep the drive level under 200 uW. These are general Pierce-oscillator rules, not Kyocera figures.++++++## Pinout++| Pad | Name | Type | Function |+|---|---|---|---|+| 1 | 1 | passive | Crystal electrode: the one Kyocera draws with an R0.3 inner corner (left in the bottom view) |+| 2 | 2 | passive | Crystal electrode, the other side of the quartz blank |++There is no ground, case or no-connect pad. Kyocera numbers neither electrode and the crystal is not polarised: either pad may go to XIN or XOUT. Adom calls the electrode with the R0.3 corner pad 1 so the symbol, footprint and 3D model agree, but turning the part 180 degrees changes nothing electrically.++++## Ordering variants++Every CX3225GA part number uses the same package and land pattern, so the symbol, footprint and 3D model on this page fit any of them. Only the electrical rating changes. The part number is built as `CX3225GA` + frequency in kHz (5 digits) + load capacitance (2 characters) + tolerance + temperature range + temperature stability + individual specification:++| Field | This part | Other choices in the catalog |+|---|---|---|+| Frequency | `08000` = 8.000 MHz | 8,000 to 54,000 kHz |+| Load capacitance | `D0` = 8.0 pF | D to H with a decimal digit: 8.0 to 12.9 pF (for example `D1` = 8.1 pF) |+| Frequency tolerance | `P` = +-50 ppm | G +-15, H +-20, J +-25, K +-30, M +-40, P +-50 ppm |+| Operating temperature | `T` = -40 to +150 C | L -30 to 85, P -40 to 85, R -40 to 105, S -40 to 125, T -40 to 150 C |+| Temperature stability | `V` = +-150 ppm | Q +-30 to W +-200 ppm (the wider ranges allow only the looser grades) |+| Specification | `TT` (individual) | `CC` standard |++ESR depends on frequency (Table 1): 500 ohm for 8 to 9.8 MHz, 200 ohm for 9.8 to 14 MHz, 120 ohm for 14 to 16 MHz, 100 ohm for 16 to 54 MHz.

KiCad's only 3225 crystal model, `Crystal_SMD_3225-4Pin_3.2x2.5mm.step`, does not fit: it has four corner terminals and is 0.64 mm tall, against Kyocera's two electrodes and 0.85 +-0.1 mm. KiCad's package generator has no recipe for this package. So the model was **built by an AI (Claude) with CadQuery from Kyocera's drawing** ([provenance/tools/build_cx3225ga.py](provenance/tools/build_cx3225ga.py)), with colours taken from Kyocera's product photo (black lid, dark ceramic, gold castellations).++| Dimension (mm) | Kyocera | KiCad 3225-4Pin model | This model |+|---|---|---|---|+| Body length | 3.2 +-0.1 | 3.200 | 3.200 |+| Body width | 2.5 +-0.1 | 2.501 | 2.500 |+| Overall height | 0.85 +-0.1 | **0.640** (below the 0.75 minimum) | 0.850 |+| Base plus seal ring | 0.53 +-0.1 | not modelled | 0.530 |+| Terminals | 2 electrodes | **4 corner pads** | 2 electrodes |+| Electrode gap | 0.6 +-0.1 | n/a | 0.600 |+| Pad 1 electrode inner corner | R0.3 | n/a | 0.300 |+| Corner castellations | 4-R0.15 | n/a | 0.150 |+| End castellation width x height | 0.5 +-0.1 x 0.25 | n/a | 0.500 x 0.250 |+| Electrode height | not printed | n/a | 2.28 (measured) |+| Electrode outer edge from centre | not printed (arc) | n/a | 1.48 at the middle, 1.24 at the ends (measured) |+| Lid inset, castellation depth | not printed | n/a | 0.10, 0.10 (measured) |++The unprinted features were measured on a 600 dpi render of the catalog. That drawing is not drawn to one scale (3.2 mm is 157 px, but 2.5 mm is 129 to 145 px depending on the view), so each view is calibrated on its own printed body edges.++### Model proof: overlay on Kyocera's drawing++Red outline and blue fill: the model, projected at the drawing's scale. Black: Kyocera's top, front, end and bottom views. The bottom view shows only the electrodes, including the R0.3 corner that identifies pad 1.++++### Top marking (virtual)++Kyocera's catalog does not document this part's top marking. The product photo shows a two-line code (`19707` / `K121F` on the sample pictured) whose meaning is not published. The models therefore carry a **virtual** identification mark, `CX3225GA` / `08000D0PTVTT`, on the lid, added by `adom-aiflow-etch` (single-stroke font, 0.24 mm text, legibility gate PASS). It is an identification aid in CAD, not a claim about what is printed on the real part.++++## Detail levels for board and digital-twin viewers++::adom-component-lod{src="/adom/cx3225ga08000d0ptvtt/render/lod/manifest.json"}++| Level | File | Triangles | Draw calls | Size | Marking |+|---|---|---|---|---|---|+| high | [cx3225ga08000d0ptvtt-high.glb](lod/cx3225ga08000d0ptvtt-high.glb) | 1229 | 6 | 45 KiB | yes |+| medium | [cx3225ga08000d0ptvtt-medium.glb](lod/cx3225ga08000d0ptvtt-medium.glb) | 1229 | 6 | 34 KiB | yes |+| low | [cx3225ga08000d0ptvtt-low.glb](lod/cx3225ga08000d0ptvtt-low.glb) | 386 | 5 | 15 KiB | no |+| super-low | [cx3225ga08000d0ptvtt-super-low.glb](lod/cx3225ga08000d0ptvtt-super-low.glb) | 168 | 5 | 10 KiB | no |++All four levels share the library model's Z-up frame, units and seating, carry no footprint or silkscreen artwork, and keep both electrodes.
