Crystals Procurement Notes

Verify current lifecycle status as this specific part number may be discontinued or subject to product change notifications. Confirm that the HC-49/US package dimensions align with the target PCB layout. Ensure the 18pF load capacitance matches the circuit design requirements. Check for valid RoHS compliance documentation if required by regulatory standards. Validate supply chain availability through authorized distributors.

Crystals Selection Notes

Select this component when a 22 MHz reference signal is required for surface-mount assembly. The ±10 ppm tolerance suits general consumer electronics applications. Consider the 30 Ohm ESR value for oscillator circuit compatibility. The HC-49/US form factor allows for direct replacement of through-hole crystals in space-constrained designs without significant PCB modifications.

Crystals Part Context

This model belongs to the TXC 9C series, which focuses on high-volume consumer electronics. The series emphasizes cost-effectiveness and production stability.
