Crystals Procurement Notes

Verify the specific suffix 'MDDE' against official TXC documentation to confirm exact electrical tolerances and pinout configuration. Ensure compatibility with existing PCB footprint dimensions and soldering thermal profiles. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±20 ppm stability is required within a 5.0x3.2 mm SMD package. Consider the 10 pF load capacitance requirement for oscillator circuit design. Evaluate the -20°C to +70°C temperature range against environmental constraints. Compare ESR specifications with driver circuit capabilities to ensure reliable startup.

Crystals Part Context

This part belongs to the 7V series of quartz crystals from TXC Corporation, which focuses on standard frequency solutions for general electronic applications.
