E1SJA18-11.0592M TR

Crystals Overview

The E1SJA18-11.0592M TR is a surface-mount quartz crystal resonator manufactured by Ecliptek, designed for parallel fundamental operation. It features a nominal frequency of 11.0592 MHz with a load capacitance of 18 pF and an equivalent series resistance of 70 Ohms. The device operates within a temperature range of -40°C to +85°C, maintaining a frequency tolerance of ±15 ppm at 25°C and ±30 ppm across the full range. Aging is specified at 5 ppm per year maximum. Constructed in a short HC-49/UP SMD package measuring 13.3 mm x 4.85 mm x 3.2 mm, it utilizes a resistance-welded metal seal and supports a drive level of 1000 µW.

Crystals Procurement Notes

Verify that the specific suffix 'TR' corresponds to tape and reel packaging requirements for your manufacturing line. Confirm that the 18 pF load capacitance matches the oscillator circuit design specifications. Ensure the operating temperature range of -40°C to +85°C meets environmental constraints. Check RoHS compliance documentation for regulatory adherence. Validate physical dimensions against PCB footprint constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 11.0592 MHz frequency is required for baud rate compatibility in serial communications. Choose based on the need for a robust SMD package with a height of 3.2 mm. Consider the 70 Ohm ESR for oscillator startup reliability. Evaluate the ±15 ppm initial tolerance against system jitter requirements. Ensure the parallel resonant characteristic aligns with the host circuit's capacitive loading.

Crystals Part Context

This part belongs to the E1S series of short HC-49/UP surface mount crystals from Ecliptek. These components are designed as direct replacements for through-hole HC-49/U units in space-constrained designs. The series offers various frequencies while maintaining consistent mechanical profiles. They are intended for general-purpose timing applications requiring stable frequency references.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/UP SMD crystals with identical 11.0592 MHz frequency, 18 pF load capacitance, and similar physical dimensions. Verify that alternative parts meet the same ±15 ppm tolerance and -40°C to +85°C temperature range. Ensure comparable ESR values to maintain oscillator stability.
