E1SHA18-16.000M TR

Crystals Overview

The E1SHA18-16.000M TR is a quartz crystal resonator from the Ecliptek E1S series, designed for surface mount applications. It features an HC49/UP short package with two pads and a height of 3.2 mm. The nominal frequency is 16.000 MHz with a load capacitance of 18 pF. Frequency tolerance is ±30 ppm at 25°C and ±50 ppm over -20°C to +70°C. Aging is limited to ±5 ppm/year maximum. Electrical specifications include a shunt capacitance of 7 pF maximum, equivalent series resistance of 50 ohms maximum, and a drive level of 1 mWatt maximum. The device operates in AT-cut fundamental mode.

Crystals Feature Summary

• Surface mount construction using HC49/UP short package with metal resistance weld seal
• AT-cut fundamental mode operation for stable parallel resonance
• Lead-free and RoHS compliant manufacturing process

Crystals Applications

• General purpose clock signal generation in electronic circuits
• Frequency reference sources for microcontroller systems

Crystals Procurement Notes

Verify that the ordering suffix matches the required tape and reel configuration for automated assembly processes. Confirm that the component meets current RoHS directives and lead-free requirements specified by the manufacturer. Ensure the selected variant aligns with the specific load capacitance and frequency stability needs of the target design application.

Crystals Selection Notes

Select this component when a standard 16 MHz surface mount crystal is required for general timing applications. Consider the ±30 ppm initial tolerance and ±50 ppm total stability over the operating temperature range. Evaluate the 18 pF load capacitance requirement against the oscillator circuit design. The HC49/UP short form factor offers a compact solution for space-constrained PCB layouts.

Crystals Part Context

This part belongs to the Ecliptek E1S series of quartz crystal resonators. The series provides various frequencies and packages optimized for surface mount technology. Ecliptek specializes in programmable oscillators and crystals to support rapid product development cycles. The E1SHA18-16.000M TR represents a standard fixed-frequency option within this portfolio.

Crystals Replacement Considerations

Direct substitutes may include other manufacturers' HC49/UP SMD crystals with identical 16.000 MHz frequency and 18 pF load capacitance. Verify mechanical dimensions and pin compatibility before substitution. Cross-reference electrical parameters such as ESR and stability limits to ensure equivalent performance in the final application.
