EA2532QA18-20.000M TR

Crystals Overview

The EA2532QA18-20.000M TR is a surface-mount quartz crystal resonator from the MultiVolt ECS-327ATQMV series, manufactured by Ecliptek. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±15 ppm and stability of ±20 ppm over the operating temperature range. The component features an equivalent series resistance (ESR) of 60 Ohms maximum and requires a load capacitance of 18 pF. It utilizes AT-cut technology for fundamental parallel resonance operation. The physical dimensions are 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height, housed in a 4-SMD, no-lead package suitable for automated assembly processes.

Crystals Feature Summary

• Utilizes AT-cut quartz technology for stable fundamental parallel resonance operation
• Designed for surface-mount applications with a compact 3.2mm x 2.5mm footprint
• Provides precise timing control with specified frequency tolerance and stability ratings

Crystals Applications

• General-purpose clock generation for microprocessors and microcontrollers
• Timing reference sources for communication interface circuits
• Oscillator circuits in consumer electronic devices requiring standard frequencies

Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 20 MHz frequency and 18 pF load capacitance. Confirm the package type is the 4-SMD no-lead variant compatible with your PCB footprint. Ensure the supplier provides documentation confirming RoHS compliance and material declarations as specified in the manufacturer's standards. Check that the delivery condition aligns with your production needs regarding reel or cut tape availability.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required with a 18 pF load capacitance specification. Consider the 60 Ohm ESR limit to ensure compatibility with the driving circuit's oscillation requirements. The 3.2mm x 2.5mm size is suitable for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the final application.

Crystals Part Context

This component belongs to the MultiVolt ECS-327ATQMV series of crystals from Ecliptek. It is distinct from other series such as the ECCM9HA18-20.000M, which features different physical dimensions and aging characteristics. The EA2532QA18-20.000M TR is specifically designed for general-purpose SMD applications, differing from higher-performance oscillator models in both function and packaging.

Crystals Replacement Considerations

Direct substitutes within the same series include the EA2532QA18-25.000M TR, which shares identical physical and electrical specifications except for the nominal frequency of 25 MHz. Cross-referencing with other manufacturers' 20 MHz crystals in the 3225 package requires verification of ESR, load capacitance, and drive level compatibility.
