E1SCA18-16.000M TR

Crystals Overview

The E1SCA18-16.000M TR is a quartz crystal resonator from the Ecliptek E1S series, designed for surface mount applications. It operates at a nominal frequency of 16.000 MHz with an AT-Cut fundamental mode. The component features a parallel resonant configuration and an 18pF load capacitance. Electrical specifications include a frequency tolerance of ±50ppm at 25°C and stability of ±100ppm over the -40°C to +85°C operating range. Aging is limited to ±5ppm/year maximum. The unit utilizes a resistance-welded seal within an HC-49/US short package, measuring 13.3mm in length, 4.85mm in width, and 3.2mm in height. Equivalent series resistance is 50 Ohms maximum, with shunt capacitance capped at 7pF.

Crystals Feature Summary

• Surface mount construction utilizing a resistance-welded metal seal for environmental protection
• AT-Cut fundamental mode operation ensuring stable timing performance
• RoHS compliant and lead-free manufacturing process

Crystals Applications

• Timing circuits in consumer electronics requiring precise clock signals
• Microcontroller oscillator inputs for embedded system control
• Communication modules needing stable carrier frequencies

Crystals Procurement Notes

Verify that the ordering suffix matches the required reel quantity specification. Confirm RoHS compliance status aligns with current regulatory requirements for the target market. Ensure the HC-49/US short footprint dimensions are compatible with the PCB layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 16 MHz surface mount crystal with 18pF load capacitance is required. Consider the ±100ppm wide temperature stability range suitable for general commercial environments. Verify that the 50 Ohm ESR fits the oscillator circuit design parameters and that the 1mW drive level does not exceed the source capabilities.

Crystals Part Context

This part belongs to the Ecliptek E1S series of SMD crystals. It shares the standard HC-49/US short physical form factor common across many manufacturers. The 'TR' suffix indicates tape and reel packaging for automated assembly processes. It serves as a direct replacement for through-hole variants where space savings are necessary.

Crystals Replacement Considerations

Cross-reference with other manufacturers offering HC-49/US SMD packages. Ensure substitute parts match the 16.000MHz frequency, 18pF load capacitance, and 50 Ohm ESR limits. Verify that alternative components support the same -40°C to +85°C operating temperature range.
