ECS-110.5-S-4

Crystals Overview

The ECS-110.5-S-4 is a fundamental mode quartz crystal resonator manufactured by ECS Inc International, designed for through-hole mounting in HC-49/US packages. It operates at a nominal frequency of 11.0592 MHz with a specified frequency tolerance of ±30 ppm and frequency stability of ±50 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and utilizes series load capacitance configuration. It supports an operating temperature range of -10°C to +70°C.

Crystals Feature Summary

• Fundamental mode operation within the HC-49/US package
• Series load capacitance configuration
• Through-hole mounting capability

Crystals Applications

• Microcontroller clock circuits
• Serial communication interfaces
• Embedded system timing references

Crystals Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package orientation and lead form against schematic requirements. Validate ESR specifications against oscillator circuit design constraints. Ensure operating temperature range meets environmental conditions.

Crystals Selection Notes

Select this component when fundamental mode operation is required for precise timing applications. Consider the 60 Ohm ESR value for oscillator circuit compatibility. Verify that the HC-49/US package fits the PCB layout constraints. Check if the ±30 ppm tolerance meets system accuracy requirements.

Crystals Part Context

This part belongs to the HC-49USX Series of quartz crystals from ECS Inc International. It is distinct from surface mount variants like the ECS-110.5-20-5G3XDS-TR which uses CSM-7X-3L packaging. The model designation indicates specific frequency and package characteristics unique to this through-hole product line.

Crystals Replacement Considerations

Direct substitutes must match the 11.0592 MHz frequency, HC-49/US package, and 60 Ohm ESR. Verify equivalent series resistance and load capacitance parameters before substitution.
