MXJFHJI20M0

Crystals Overview

The Meritek MXJFHJI20M0 is a 20 MHz crystal oscillator housed in an HC49S package. It features a frequency tolerance of ±30ppm and stability of ±50ppm across the -40°C to +85°C temperature range. The component operates with a load capacitance of 20pF and has a maximum series resistance of 40 Ohms. It is lead-free and RoHS compliant, designed for surface-mount or through-hole integration depending on specific board requirements.

Crystals Feature Summary

• Provides precise timing signals at 20 MHz
• Ensures stable operation within industrial temperature ranges
• Utilizes standard HC49S form factor for compatibility

Crystals Applications

• Microcontroller clock sources
• Communication equipment timing
• Consumer electronics oscillators

Crystals Procurement Notes

Verify the exact load capacitance requirement matches the target circuit design, as mismatched capacitance affects frequency accuracy. Confirm that the HC49S package dimensions align with the PCB footprint. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status for regulatory adherence.

Crystals Selection Notes

Select this component when a 20 MHz reference is required with moderate stability needs. Consider the ±30ppm tolerance against system timing budgets. Evaluate the 40 Ohm impedance against driver capability. Compare against higher precision alternatives if tighter ppm limits are necessary for the application.

Crystals Part Context

This part belongs to Meritek's general-purpose crystal lineup. It serves as a fundamental timing element for digital circuits. The HC49S package is widely recognized for its mechanical robustness and ease of handling during assembly processes.

Crystals Replacement Considerations

Substitutes must match the 20 MHz frequency, HC49S package, and 20pF load capacitance. Verify that alternative crystals meet or exceed the ±30ppm tolerance and 40 Ohm ESR specifications to ensure functional equivalence.
