E1SJA18-32.000M TR

Crystals Overview

The E1SJA18-32.000M TR is a quartz crystal resonator from the Ecliptek E1S series, designed for surface mount applications. It operates at a nominal frequency of 32 MHz with an AT-cut fundamental mode. The component features a parallel resonance configuration and utilizes a resistance-welded metal seal within a short HC-49/UP SMD package measuring 13.3mm x 4.85mm x 3.2mm. 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 range of -40°C to +85°C. The unit complies with RoHS standards and includes lead-free construction.

Crystals Feature Summary

• Surface mount construction utilizing a resistance-welded metal seal for environmental protection
• AT-cut fundamental mode operation ensuring stable parallel resonance characteristics
• Compliance with RoHS directives and lead-free manufacturing processes

Crystals Applications

• Microcontroller oscillator circuits requiring precise clock timing
• Communication modules utilizing standard baud rate frequencies
• Industrial control systems operating in extended temperature environments

Crystals Procurement Notes

Verify that the specific order matches the exact suffix MTR, which indicates tape and reel packaging, rather than cut tape or bulk formats. Confirm that the receiving facility has appropriate handling procedures for surface mount components. Ensure that the storage environment maintains conditions suitable for electronic passive components prior to assembly. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential design changes.

Crystals Selection Notes

Select this component when a 32 MHz reference signal is required for digital logic or communication interfaces. The 18 pF load capacitance specification must align with the host circuit's external capacitor values to achieve accurate frequency output. Consider the ±30 ppm stability over the full temperature range to ensure system reliability under thermal variation. The short HC-49/UP form factor allows for compact board layouts compared to traditional through-hole variants.

Crystals Part Context

This part belongs to the E1S series of short HC-49/UP surface mount crystals manufactured by Ecliptek. The series provides various frequency options within the same physical footprint and electrical parameter framework. These components are engineered to replace legacy through-hole crystals in modern high-density PCB designs while maintaining similar performance profiles.

Crystals Replacement Considerations

Direct substitutes include other E1SJA18-32.000M TR units from Ecliptek or compatible equivalents from Abracon. Verify that replacement parts maintain identical package dimensions, pin configurations, and electrical specifications such as load capacitance and frequency tolerance.
