Crystals Procurement Notes

Verify the specific frequency tolerance requirement against available datasheet versions, as sources indicate both ±10 ppm and ±30 ppm specifications for this part number. Confirm the exact package dimensions and pin configuration match the target PCB footprint before ordering. Ensure the supplier provides official documentation from Shenzhen SCTF Electronics to guarantee component authenticity and performance consistency.

Crystals Selection Notes

Select this component when a compact 12 MHz reference is required for space-constrained designs. The 4-SMD no-lead form factor supports automated surface-mount assembly processes. Consider the operating temperature range of -40°C to +85°C for industrial or automotive environments. Evaluate the ESR limit of 100 Ohms against the oscillator circuit requirements to ensure stable startup and operation.

Crystals Part Context

This part belongs to the SCTF SX3B series of passive crystals. The series utilizes AT-cut quartz elements housed in super-small ceramic packages. These components are engineered for applications demanding precise timing in consumer electronics and industrial control systems where size and thermal stability are critical constraints.

Crystals Replacement Considerations

Cross-reference with other 12 MHz SMD crystals from SCTF such as the SX3B12.288F1210F30 if a different frequency is acceptable. Verify compatibility with existing oscillator circuits when substituting with generic equivalents, ensuring load capacitance and ESR parameters align with the original design specifications.
