Crystals Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply. Confirm that the specific 20 pF load capacitance matches the target circuit design requirements. Ensure the ±30 ppm stability specification meets the system timing accuracy needs. Check for updated EOL notifications from the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 30 MHz reference signal is required in space-constrained portable electronics. The 3225 footprint offers a balance between performance and board area efficiency. Consider the glass-sealed variant over resin-packaged options if long-term stability under thermal cycling is critical. Verify that the driving level remains within safe operational limits for the specific oscillator circuit topology.

Crystals Part Context

This part belongs to the TXC 7A series of SMD glass-sealed crystals. The series is characterized by its robust environmental performance and suitability for consumer electronics manufacturing. It serves as a passive frequency control element in microcontroller clock circuits and communication interfaces.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 20 pF load capacitance, and 3225 package dimensions. Verify equivalent electrical parameters such as ESR and shunt capacitance. Cross-reference with other manufacturers' 3225 glass-sealed crystal lines ensuring identical pinout and mounting specifications.
