E1SCA18-8.000M TR

Crystals Overview

The E1SCA18-8.000M TR is a surface-mount quartz crystal resonator manufactured by Ecliptek, operating at a nominal frequency of 8 MHz. It utilizes an AT-cut fundamental mode within the HC-49/US package form factor. The component features a load capacitance of 18 pF and offers a frequency tolerance of ±50 ppm with a stability of ±100 ppm across the operating temperature range. Designed for SMD/SMT installation, it supports a maximum drive level of 1 mW and operates reliably between -40°C and +85°C.

Crystals Feature Summary

• AT-cut fundamental resonance mode ensures stable oscillation without requiring additional harmonic filtering circuits.
• Surface-mount construction in a compact HC-49/US footprint facilitates automated assembly processes.
• Compliance with RoHS 2011/65 and 2015/863 directives supports environmental regulatory requirements.

Crystals Applications

• Microcontroller unit (MCU) clock sources
• General-purpose digital logic timing references
• Consumer electronic device synchronization

Crystals Procurement Notes

Verify that the specific order matches the E1SCA series designation to ensure correct tolerance specifications. Confirm the package type aligns with PCB layout requirements. Check current availability status as supply chain conditions may affect lead times. Ensure compliance documentation is requested if required for final product certification processes.

Crystals Selection Notes

Select this component when a standard 8 MHz reference is needed for general digital applications. The ±50 ppm tolerance suits most non-critical timing scenarios. Consider the 18 pF load capacitance for circuit matching calculations. Evaluate thermal performance against the -40°C to +85°C operational range limits before integration into the design.

Crystals Part Context

This part belongs to the E1S series of quartz crystals from Ecliptek. The series provides various frequency options in standardized packages. The E1SCA variant specifically denotes surface-mount compatibility. This family is designed for cost-effective mass production in consumer electronics.

Crystals Replacement Considerations

Direct substitutes include other 8 MHz SMD crystals with identical 18 pF load capacitance and similar physical dimensions. Verify equivalent electrical parameters such as ESR and drive level before substitution.
