Crystals Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to ensure authenticity. Confirm that the package type matches the required footprint on the printed circuit board. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the load capacitance requirements align with the target oscillator circuit design parameters before procurement.

Crystals Selection Notes

Select this component when a 20.48 MHz clock source is required for embedded systems or communication interfaces. The 12pF load capacitance must match the external capacitor values in the oscillator circuit to maintain accuracy. Consider the ±15ppm tolerance for applications requiring precise timing synchronization. The small SMD form factor suits high-density PCB layouts where space is limited.

Crystals Part Context

This crystal belongs to the C2E series of surface-mount resonators from Aker Technology Corp. The series offers various frequencies and package sizes optimized for consumer electronics and industrial applications.
