Crystals Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure exact electrical parameter alignment, particularly regarding load capacitance and frequency tolerance variations within the C5S series. Confirm that the requested part number matches the intended operating temperature range and physical footprint requirements for the target PCB layout. Cross-reference datasheet revisions to validate current compliance status and manufacturing availability before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz reference with ±10 ppm stability and 18 pF load capacitance is required for surface-mount designs. Ensure the circuit driving capability aligns with the 35 Ω ESR and 100 µW drive level specifications. Verify that the 5.0 x 3.2 mm package fits the designated board space and that the operating temperature range meets the application's environmental constraints without requiring extended grade variants.

Crystals Part Context

This part belongs to the C5S series of surface-mount quartz crystals from Aker Technology Corp, which are engineered for compact electronic designs. The series provides fundamental mode oscillation options suitable for various digital and communication applications. The C5S designation indicates a standard surface-mount form factor, distinguishing it from through-hole or specialized automotive-grade variants within the manufacturer's broader portfolio.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz SMD crystals with identical 18 pF load capacitance and ±10 ppm tolerance, such as the C5S-12.000-18-1020-X-R if pinout compatibility is verified. Ensure any replacement maintains the same 4-pin SMD footprint and 35 Ω ESR characteristics to preserve circuit performance.
