Crystals Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet to ensure compatibility with your circuit design. Confirm RoHS compliance status and lead-free specifications if required for regulatory adherence. Cross-reference the package outline drawing with your PCB footprint library to guarantee accurate placement and soldering reliability during production.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in space-constrained designs. Ensure the oscillator circuit can support the specified 18 pF load capacitance to maintain accuracy. Evaluate the thermal environment to confirm operation within the -30°C to +85°C range. Consider the ESR value for proper startup conditions in low-power applications.

Crystals Part Context

This part belongs to the 8Z series of miniature quartz crystals from TXC Corporation. The series is characterized by small form factors suitable for portable electronics and compact devices. These components are manufactured using precision tuning techniques to achieve tight frequency tolerances and stable performance over time and temperature variations.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 18 pF load capacitance, and 2.5x2 mm SMD package. Verify that alternative parts meet the same ±10 ppm tolerance and -30°C to +85°C operating range. Check for identical ESR and drive level specifications to ensure circuit compatibility.
