Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against the official Meritek datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the final application. Ensure compatibility with standard reflow soldering profiles for surface mount components.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with moderate stability specifications. Consider the 16 pF load capacitance requirement for circuit matching. Evaluate the -20°C to +70°C temperature range against operational conditions. Compare ESR values with oscillator input impedance requirements.

Crystals Part Context

This part belongs to the MX3 series of surface mount crystals from Meritek Electronics. The series offers various frequencies and packages for general-purpose timing applications. The MX3FHHC40M0 specifically targets 40 MHz applications in consumer and industrial electronics where size and cost efficiency are prioritized over high-stability performance.

Crystals Replacement Considerations

Check for direct substitutes within the Meritek MX3 series with identical frequency and load capacitance. Verify cross-compatibility with other manufacturers' 3225-style 40 MHz crystals if supply chain constraints exist. Ensure replacement parts match the fundamental mode and ESR specifications.
