E1SBA18-8.000M TR

Crystals Overview

The E1SBA18-8.000M TR is a quartz crystal resonator manufactured by Ecliptek, designed for surface-mount applications. It operates at a nominal frequency of 8 MHz with a frequency tolerance of ±50 ppm and stability of ±100 ppm over the operating temperature range. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 90 Ohms maximum. It utilizes an AT-cut fundamental mode of operation with a drive level of 1 mWatt maximum. The package is HC-49/US SMD with dimensions of 11.60mm x 4.85mm x 3.20mm. It supports a storage temperature range of -55°C to +125°C and complies with RoHS standards.

Crystals Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging when placing orders. Confirm the specific frequency tolerance requirements match the ±50 ppm specification provided in the datasheet. Ensure compatibility with the 18 pF load capacitance in the target circuit design. Check for any specific handling instructions related to the surface-mount package type during assembly processes.

Crystals Selection Notes

Select this component when a standard 8 MHz reference is required for surface-mount PCB layouts. Consider the ±50 ppm tolerance if higher precision is not critical. Verify that the 90 Ohm ESR fits within the oscillator circuit constraints. Ensure the operating temperature range meets the environmental demands of the final application. Compare against other E1S series variants for different frequency or tolerance options.

Crystals Part Context

This part belongs to the E1S series of quartz crystals from Ecliptek. The series offers various frequencies and tolerances in standardized packages. The E1SBA18 variant specifically denotes the 8 MHz frequency point within this lineup. It shares common mechanical and electrical characteristics with other members of the family, differing primarily in frequency and tolerance specifications.

Crystals Replacement Considerations

Direct substitutes may include other 8 MHz HC-49/US SMD crystals with similar 18 pF load capacitance and ±50 ppm tolerance. Verify pinout compatibility and physical dimensions before substitution. Consult manufacturer cross-reference lists for approved alternatives.
