Crystals Procurement Notes

Verify the specific package variant against the HC49S designation when sourcing. Confirm that the required operating temperature range aligns with the -20°C to +70°C specification for your application environment. Ensure compatibility with standard SMT reflow soldering processes as indicated by the manufacturer's compliance data.

Crystals Selection Notes

Select this component when a 40 MHz reference frequency is required in a compact surface-mount form factor. Consider the 18 pF load capacitance requirement for circuit matching. Evaluate the ±10 ppm tolerance against system jitter requirements. The HC49S package offers a balance between size and performance for general consumer electronics.

Crystals Part Context

Meritek Electronics Corporation produces passive components including crystals and resonators. The MXJEAFC40M0 belongs to their crystal oscillator lineup, targeting applications needing precise timing references. The HC49S package is a common industry standard for through-hole or surface-mount crystal implementations, offering reliable performance in various electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, HC49S package, 18 pF load capacitance, and ±10 ppm tolerance. Verify thermal range compatibility (-20°C to +70°C). Check equivalent series resistance limits (max 80 Ohms) for circuit stability. Consult manufacturer cross-reference lists for verified alternatives.
