E1SBA18-3.6864M TR

Crystals Overview

The E1SBA18-3.6864M TR is a quartz crystal resonator manufactured by Ecliptek, operating at a nominal frequency of 3.6864 MHz. It utilizes an HC-49/UP surface mount package with dimensions of 13.3 mm in length, 4.85 mm in width, and 3.2 mm in height. The component features a parallel fundamental mode of operation with a load capacitance of 18 pF and a maximum equivalent series resistance of 200 Ohms. Frequency stability is rated at ±100 ppm over the operating temperature range of -20°C to +70°C, with a tolerance of ±50 ppm at 25°C. Aging is specified at a maximum of 5 ppm per year, and it supports a drive level of 1 mW.

Crystals Feature Summary

• Parallel fundamental resonance mode operation
• Metal resistance weld seal for environmental protection

Crystals Applications

• General purpose timing circuits requiring 3.6864 MHz reference
• Embedded systems utilizing standard crystal interfaces
• Consumer electronics compatible with HC-49/UP form factors

Crystals Procurement Notes

Verify that the target circuit design accommodates the specific physical dimensions of the HC-49/UP SMD package, as it differs from traditional through-hole variants. Confirm that the system's oscillator circuit can support the 18 pF load capacitance requirement to ensure accurate frequency generation. Ensure the operating environment remains within the specified -20°C to +70°C range to maintain the stated ±100 ppm stability. Check for RoHS compliance documentation if required by local regulations.

Crystals Selection Notes

Select this component when a surface mount solution is required for applications traditionally served by HC-49/UP crystals. It is suitable for designs needing a 3.6864 MHz frequency with moderate stability requirements. Consider the 200 Ohm ESR limit when designing the oscillator feedback network. This part is appropriate for cost-sensitive applications where the larger SMD footprint is acceptable compared to smaller MEMS or ceramic oscillators.

Crystals Part Context

This part belongs to the Ecliptek line of quartz crystal resonators, which are designed for surface mount assembly.
