Crystals Procurement Notes

Verify the specific suffix configuration against design requirements, as variations exist within the HC49SDLF series regarding temperature ratings and packaging. Confirm that the 60 Ohm ESR aligns with the oscillator circuit's drive level capabilities to prevent over-driving or failure to start. Ensure the commercial temperature range meets the operational environment constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a surface-mount solution is required for 11 MHz timing applications. The HC-49/US form factor offers a balance between mechanical robustness and space efficiency compared to standard through-hole packages. Consider the ±30ppm tolerance sufficient for most standard communication protocols. Verify that the 20pF load capacitance matches the system's total capacitive load requirements.

Crystals Part Context

This part belongs to the HC49SDLF series, which represents Fox Electronics' line of surface-mount crystals derived from the traditional HC-49/U footprint. This series bridges the gap between legacy through-hole reliability and modern SMD manufacturing processes. The FC4STCBMF11.0 specifically targets cost-sensitive designs requiring standard commercial grade performance without the need for extended industrial temperature ranges.
