Crystals Procurement Notes

Verify the exact load capacitance requirement (e.g., 18pF vs 20pF) against the target oscillator circuit design before procurement. Confirm that the operating temperature range meets the application's environmental specifications. Ensure the soldering profile complies with the manufacturer's reflow recommendations to maintain frequency accuracy. Cross-reference the full part number suffix to confirm pinout and package dimensions match the PCB footprint.

Crystals Selection Notes

Select this component when a stable 16 MHz reference is required for microcontrollers or communication interfaces. Consider the load capacitance compatibility with the host oscillator circuit to avoid frequency pulling. Evaluate the need for electromagnetic shielding provided by the metal can package versus cost-sensitive plastic alternatives. Verify that the frequency tolerance meets the system's synchronization requirements.

Crystals Part Context

This crystal unit belongs to TXC Corporation's general-purpose surface-mount crystal lineup. It serves as a passive timing component essential for generating precise clock signals in digital systems. The AA series typically denotes a specific form factor and mounting style optimized for automated assembly processes in consumer and industrial electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes must match the 16 MHz frequency, load capacitance, and physical dimensions. Check equivalent parts from manufacturers like Epson, NDK, or Murata with identical pin configurations and electrical tolerances. Ensure the replacement maintains the same frequency stability and temperature characteristics.
