Crystals Procurement Notes

Verify the specific suffix 'XIAR' against manufacturer documentation to confirm the exact load capacitance and tolerance ratings, as suffixes often denote critical electrical variations. Ensure the procurement channel provides valid traceability for RoHS3 compliance status. Cross-reference the part number with official CTS datasheets to confirm current availability and lifecycle status before finalizing orders.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±10ppm tolerance. The 10pF load capacitance must match the oscillator circuit design. Consider the 4-SMD footprint constraints and the -20°C to 70°C operating temperature range relative to the application environment requirements.
