Crystals Procurement Notes

Verify the specific suffix configuration against official TXC documentation to ensure compatibility with required load capacitance and stability parameters. Confirm that the 4-SMD footprint matches the target PCB layout constraints. Check current availability status through authorized distributors as supply levels may fluctuate. Ensure compliance with RoHS standards if required by the final assembly specifications.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal with ±10 ppm stability is required. The 12 pF load capacitance must align with the oscillator circuit design. Consider the 50 Ohm ESR value for impedance matching requirements. The 3.2x2.5 mm package size offers a balance between performance and board space efficiency compared to larger packages.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series is characterized by small form factors and high reliability for consumer and industrial electronics. It serves as a passive frequency-determining element within active oscillator circuits, providing the necessary resonant frequency for system timing operations.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 12 pF load capacitance and ±10 ppm stability. Verify package dimensions and pinout compatibility before substitution. Alternative parts from different manufacturers must match the ESR and operating temperature range specifications to ensure circuit functionality.
