E1SJA18-6.144M TR

Crystals Overview

The E1SJA18-6.144M TR is a quartz crystal resonator manufactured by Ecliptek, designed for surface-mount applications. It operates at a nominal frequency of 6.144 MHz with an AT-cut fundamental parallel mode. The component features a resistance-welded SMD package measuring 13.3 mm in length, 4.85 mm in width, and 3.2 mm in height. It supports a load capacitance of 18 pF and offers a frequency tolerance of ±15 ppm at 25°C, extending to ±30 ppm across the operating temperature range of -40°C to +85°C. The device ensures aging stability of 5 ppm per year and functions with a drive level of 1000 µW.

Crystals Procurement Notes

Verify that the ordered part number matches the specific suffix requirements for tape and reel packaging. Confirm RoHS compliance status aligns with project environmental standards. Ensure the load capacitance specification matches the target circuit design requirements before integration.

Crystals Selection Notes

Select this component when a standard 6.144 MHz reference is required for surface-mount assembly. Consider the physical dimensions and mounting style for PCB layout compatibility. Evaluate the frequency stability and aging characteristics against the system's long-term timing accuracy requirements.

Crystals Part Context

This part belongs to the E1SJA series of short HC-49/UP SMD crystals from Ecliptek. These components are engineered as direct replacements for traditional through-hole crystals in modern compact electronics. The series provides reliable performance for cost-sensitive applications requiring precise frequency control.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/UP SMD crystals with identical 6.144 MHz frequency, 18 pF load capacitance, and compatible physical footprint. Verify equivalent electrical parameters such as ESR and drive level sensitivity when cross-referencing alternative sources.
