E1SJA18-15.360M TR

Crystals Overview

The E1SJA18-15.360M TR is a surface-mount quartz crystal resonator manufactured by Ecliptek, operating at a nominal frequency of 15.36 MHz. It utilizes an AT-cut fundamental mode and features parallel resonance with a load capacitance of 18 pF. The component exhibits a frequency tolerance of ±15 ppm at 25°C and ±30 ppm across the industrial temperature range of -40°C to +85°C. Aging stability is rated at 5 ppm per year maximum. Electrical characteristics include a shunt capacitance (C0) of 7 fF and an equivalent series resistance (ESR) of 60 Ohms. The drive level is limited to 1 mW, and it complies with RoHS standards.

Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer designation as Ecliptek or Abracon depending on the supply chain source. Ensure the order matches the exact frequency tolerance requirements of ±15 ppm at 25°C. Check for RoHS compliance documentation if required for regulatory submission. Validate the package dimensions against PCB footprint specifications before finalizing procurement.

Crystals Selection Notes

Select this component for applications requiring precise 15.36 MHz timing within industrial temperature limits. The 18 pF load capacitance requires matching external capacitors in the circuit design. Consider the 60 Ohm ESR value for oscillator compatibility. The 1 mW drive level limit necessitates checking the host oscillator circuit output impedance. This part is suitable for space-constrained designs due to its SMD form factor.

Crystals Part Context

This part belongs to the E1S series of short HC-49/UP surface mount crystals. The series offers various frequencies and tolerances for general-purpose timing applications. The JA suffix typically denotes specific package variations within the E1S family. These components are designed for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes may include other E1S series variants with identical 15.36 MHz frequency and 18 pF load capacitance. Verify that alternative parts match the ±15 ppm tolerance and -40°C to +85°C temperature range. Ensure replacement components maintain the same HC-49/UP SMD footprint and pin configuration.
