Crystals Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 12 pF load capacitance and 45 Ω ESR limit. Confirm compliance with RoHS standards if environmental regulations apply to the final product. Ensure the operating temperature range of -10°C to +70°C aligns with the intended application environment before procurement.

Crystals Selection Notes

Select this component when a 16.67 MHz fundamental frequency is required for surface-mount designs. The 12 pF load capacitance must match the oscillator circuit design to ensure accurate frequency performance. Consider the ±15 ppm initial tolerance and ±30 ppm total stability for applications requiring moderate precision within the specified temperature range.

Crystals Part Context

This component belongs to the C7S series of surface-mount quartz crystals from Aker Technology Corp. The series offers various frequencies and packages tailored for compact electronic designs. As a fundamental mode crystal, it provides reliable oscillation without the complexity of overtone circuits, making it suitable for standard digital timing applications.

Crystals Replacement Considerations

Direct substitutes include other 16.67 MHz SMD crystals with identical 12 pF load capacitance and compatible physical dimensions. Verify that alternative parts meet the same 45 Ω ESR and ±15 ppm tolerance requirements to maintain circuit performance.
