E3X240121ZA2

Crystals Overview

The E3X240121ZA2 is a surface-mount crystal resonator manufactured by Eaton Electronics. It operates at a fundamental frequency of 24 MHz with a load capacitance of 12 pF and an initial frequency tolerance of ±10 ppm. The component utilizes a 4-SMD, no-lead package in the 1210 (3225 metric) footprint, measuring 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. It supports soldering via reflow processes and is designed for operation within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Provides stable oscillation at 24 MHz with high precision ±10 ppm initial tolerance
• Designed for automated surface-mount assembly using standard reflow soldering techniques
• Compact 1210 form factor suitable for space-constrained printed circuit board layouts

Crystals Applications

• Microcontroller clock sources requiring precise timing references
• Communication module oscillator circuits
• Digital signal processing system clocks

Crystals Procurement Notes

Verify the specific frequency stability rating against project requirements, as distributor listings may indicate varying stability values such as 50 PPM or 20 PPM for similar series parts. Confirm the package dimensions match the target PCB footprint exactly. Ensure the selected variant meets the required operating temperature range for the intended environment before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 24 MHz reference is needed with tight initial accuracy. Compare the 1210 package size against available board space relative to other series options like the E9X or E2X families. Consider the load capacitance requirement of the host oscillator circuit to ensure proper frequency matching without external trimming components.

Crystals Part Context

This part belongs to the E3X series of crystal resonators from Eaton Electronics. The series offers various frequencies and package sizes optimized for SMT production. The E3X240121ZA2 specifically addresses the need for a compact, reliable 24 MHz source in modern electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes include other Eaton E3X series variants with identical electrical parameters but different packaging suffixes. Cross-brand replacements require matching the 24 MHz frequency, 12 pF load capacitance, and 1210 footprint while verifying thermal and stability specifications.
