Crystals Procurement Notes

Verify the specific suffix configuration against current manufacturer documentation to ensure compatibility with required load capacitance and temperature range specifications. Confirm availability status as lifecycle changes may affect supply chain continuity. Cross-reference pinout and footprint dimensions with target PCB design files prior to procurement to prevent assembly errors.

Crystals Selection Notes

Select this component when a 44 MHz fundamental frequency with ±15ppm tolerance is required. Ensure the application circuit provides an 8pF load capacitance to maintain accuracy. Consider the 4-SMD package size for board space limitations. Verify that the operating temperature range meets the environmental requirements of the final product deployment.

Crystals Part Context

This part belongs to the CTS 416 Series of surface-mount crystals. The series offers various frequencies and package options designed for general-purpose timing applications. The 416F440XXAKT specifically targets high-frequency stability needs within a small form factor, distinguishing it from larger through-hole or older SMD variants in the manufacturer's portfolio.

Crystals Replacement Considerations

Consult official CTS-Frequency Controls substitution guides for direct replacements. Verify electrical equivalence including frequency, load capacitance, and ESR. Check package compatibility and thermal characteristics before integrating alternative components into existing designs.
