Crystals Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with current production requirements. Confirm that the 100 Ohm ESR specification aligns with the oscillator circuit design parameters. Check for any recent discontinuance notifications or lifecycle changes directly from TXC Corporation before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 12 MHz reference with ±30 ppm stability is required in a small form factor. Ensure the target application operates within the -20°C to +70°C temperature range. Verify that the circuit design can accommodate the 18 pF load capacitance and 100 µW excitation level to maintain optimal performance and longevity.

Crystals Part Context

This part belongs to the 7M series of seam-sealed crystals from TXC Corporation. These units are engineered for general-purpose timing applications where moderate stability meets strict size constraints. The series provides a balance between performance and cost-effectiveness for consumer electronics and industrial control modules.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 3.2x2.5mm package, and ±30 ppm stability. Verify load capacitance and ESR limits before cross-referencing alternative manufacturers.
