EA3250HA18-16.000M TR

Crystals Overview

The EA3250HA18-16.000M TR is a quartz crystal resonator manufactured by Ecliptek, designed for surface-mount applications. It operates at a nominal frequency of 16.000 MHz with a parallel resonant mode. The device features an AT-cut fundamental vibration and includes a load capacitance of 18pF. Frequency stability is specified at ±15ppm at 25°C and ±30ppm over the operating temperature range of -20°C to +70°C. Aging is limited to ±3ppm per year maximum. Electrical characteristics include a maximum shunt capacitance of 7pF, equivalent series resistance of 40 Ohms maximum, and a drive level of 5pF maximum. The component utilizes a ceramic package measuring 3.2mm x 5.0mm x 1.0mm with four pads.

Crystals Feature Summary

• AT-cut fundamental vibration mode ensures stable oscillation performance
• Parallel resonant configuration with 18pF load capacitance
• Surface-mount ceramic package design for automated assembly

Crystals Applications

• Embedded communication systems requiring precise timing
• Microcontroller clock sources in consumer electronics
• Industrial control boards needing stable frequency references

Crystals Procurement Notes

Verify that the ordering suffix matches the required reel packaging specification. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the supplier provides documentation confirming the 16.000MHz nominal frequency and ±15ppm tolerance at 25°C. Check that the ceramic package dimensions match the PCB footprint requirements. Validate the operating temperature range suitability for the intended application environment.

Crystals Selection Notes

Select this component when a 16MHz reference is required with high short-term stability. The ±15ppm tolerance at room temperature suits precision digital interfaces. Consider the -20°C to +70°C range against ambient conditions. The 18pF load capacitance must match the oscillator circuit design. Evaluate the 40 Ohm ESR limit for power consumption constraints in low-power designs.

Crystals Part Context

This part belongs to Ecliptek's standard quartz crystal lineup, specifically the EA3250 series. These components are designed as drop-in replacements for various 3250-sized crystal footprints. The product line emphasizes quick-turn availability for programmable frequencies. The model number encodes the size, cut, load capacitance, and frequency specifications directly.

Crystals Replacement Considerations

Direct substitutes must match the 3250 SMD footprint and 16.000MHz frequency. Verify identical 18pF load capacitance and ±15ppm tolerance. Ensure the replacement supports parallel resonance and AT-cut operation. Check compatibility with existing oscillator circuit parameters.
