E1SJA18-5.000M TR

Crystals Overview

The E1SJA18-5.000M TR is a quartz crystal resonator manufactured by Ecliptek, designed for surface mount applications. It operates at a nominal frequency of 5.000 MHz with an AT-cut fundamental mode. The component features a parallel resonance configuration and utilizes a resistance-welded seal within the HC-49/US package. Electrical specifications include a load capacitance of 18 pF, a maximum equivalent series resistance of 150 Ohms, and a drive level of 1000 µW. Frequency tolerance is ±15 ppm at 25°C, expanding to ±30 ppm across the operating range of -40°C to +85°C. Aging stability is rated at 5 ppm per year maximum.

Crystals Procurement Notes

Verify that the specific order matches the E1SJA18-5.000M TR designation to ensure correct frequency and package type. Confirm compliance requirements align with project specifications. Check current availability status as supply constraints may affect fulfillment timelines. Ensure storage conditions meet manufacturer guidelines to maintain component integrity prior to assembly.

Crystals Selection Notes

Select this component when a standard 5 MHz surface mount crystal is required for cost-effective timing solutions. The HC-49/US form factor allows for automated placement processes. Consider the 18 pF load capacitance requirement to ensure circuit compatibility. Evaluate the ±15 ppm tolerance against system accuracy needs. Verify thermal performance meets operational temperature ranges.

Crystals Part Context

This part belongs to the E1S series of short HC-49/UP SMD crystals from Ecliptek. The series offers various frequency options while maintaining consistent mechanical dimensions and electrical characteristics. These components are designed for high-volume production environments requiring reliable surface mount technology integration.

Crystals Replacement Considerations

Direct substitutes must match the 5.000 MHz frequency, 18 pF load capacitance, and HC-49/US package. Verify equivalent aging rates and tolerance specifications. Cross-reference pinout compatibility if alternative manufacturers are considered.
