Crystals Procurement Notes

Verify that the specific order suffix matches the required frequency tolerance and temperature grade. Confirm the package orientation and pinout compatibility with the target PCB footprint. Ensure the load capacitance specification aligns with the host oscillator circuit design. Request the official datasheet to validate electrical parameters before finalizing procurement decisions.

Crystals Selection Notes

Select this component when space constraints require a 2.50mm x 2.00mm footprint combined with superior EMI shielding capabilities. The four-pad design is optimal for high-frequency applications sensitive to noise coupling. Consider the ±20 ppm tolerance for general-purpose wireless links where tighter tolerances are not strictly necessary. Evaluate the 80 Ohm ESR limit against the microcontroller's drive level specifications.

Crystals Part Context
