E1SCA18-14.7456M TR

Crystals Overview

The E1SCA18-14.7456M TR is a surface-mount quartz crystal resonator from the Ecliptek E1S series, designed for industrial-grade applications. It operates at a nominal frequency of 14.7456 MHz with a load capacitance of 18 pF. The component features an AT-cut fundamental mode design housed in a 3.2 mm x 1.3 mm SMD package. Frequency stability is specified at ±50 ppm at 25°C and ±100 ppm across the full industrial temperature range of -40°C to +85°C. Annual aging is limited to ±5 ppm. It complies with EU RoHS 2011/65+2015/863 and REACH standards, ensuring lead-free manufacturing and environmental safety for global deployment.

Crystals Feature Summary

• Industrial-grade wide temperature operation suitable for harsh environments

Crystals Procurement Notes

Verify current availability status as distribution channels may vary. Confirm that the specific tape and reel packaging matches production line requirements. Ensure the manufacturer's ordering suffix aligns with the required load capacitance and tolerance specifications for the target application design.

Crystals Selection Notes

Select this component when designing circuits requiring zero-error baud rates for standard serial protocols. Ensure external matching capacitors account for PCB stray capacitance to maintain the specified 18 pF load. Verify MCU drive levels do not exceed the maximum rating to prevent frequency shifts or damage during operation.

Crystals Part Context

This part belongs to the Ecliptek E1S series of quartz crystal resonators. The series provides various frequency options and tolerance grades for both consumer and industrial markets. The E1SCA18 variant specifically targets applications needing high stability in compact surface-mount form factors.

Crystals Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 18 pF load capacitance, and 3.2x1.3mm footprint. Verify equivalent industrial temperature ratings and compliance certifications before substitution.
