Crystals Procurement Notes

Verify the manufacturer part number against official FTS documentation to confirm specifications. Ensure compatibility with the target circuit's load capacitance requirements. Check for any specific handling instructions regarding ESD sensitivity during storage and assembly.

Crystals Selection Notes

Select this component when a 38.4 MHz clock source is required in a minimal space-constrained environment. Consider the 80 Ohm ESR value for impedance matching within the oscillator circuit. Evaluate the ±20 ppm stability against the system's timing tolerance requirements.

Crystals Part Context

This component belongs to the family of surface-mount quartz crystals manufactured by FTS. These devices are engineered for precision timing applications where small form factors and reliable performance are critical. The 4-SMD package type indicates leadless construction optimized for automated placement.

Crystals Replacement Considerations

The CTS-Frequency Controls 416F38422CLT is a documented similar substitute. Note that the substitute has a different ESR of 60 Ohms compared to the original 80 Ohms. Verify circuit compatibility before replacement.
