EA2532QA18-16.000M TR

Crystals Overview

The EA2532QA18-16.000M TR is a quartz crystal resonator manufactured by Ecliptek, part of the MultiVolt ECS-327ATQMV series. It operates at a nominal frequency of 16 MHz with a tolerance of ±15 ppm and stability of ±20 ppm over an operating temperature range of -40°C to +85°C. The component features a load capacitance of 18 pF, a maximum equivalent series resistance (ESR) of 80 Ohms, and a maximum drive level of 100 µW. It utilizes an AT-cut fundamental mode and is housed in a compact 3.2 mm x 2.5 mm x 0.8 mm ceramic surface-mount package with four pads.

Crystals Feature Summary

• Utilizes AT-cut fundamental resonance technology for stable oscillation performance.
• Designed for surface-mount assembly using a four-pad ceramic package structure.
• Complies with RoHS directives and restricts hazardous substances per regulatory standards.

Crystals Applications

• General-purpose timing circuits requiring precise clock signals
• Microcontroller and microprocessor system clocks
• Communication interface modules

Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing from distributors. Confirm that the requested quantity aligns with the manufacturer's factory pack size of 1000 units or cut-tape availability. Ensure the application environment remains within the specified -40°C to +85°C operational temperature range to maintain frequency stability specifications.

Crystals Selection Notes

Select this component when a 16 MHz reference signal is required with ±15 ppm initial tolerance. The 18 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm maximum ESR limit for driver strength requirements. The small 3.2mm x 2.5mm footprint is suitable for space-constrained printed circuit board layouts.

Crystals Part Context

This part belongs to the EA2532 family of surface-mount crystals from Ecliptek. It shares the standard 3.2mm x 2.5mm dimensions with other variants in the series but differs in frequency and tolerance specifications. The QA suffix typically denotes specific quality or tolerance grades within the product line.

Crystals Replacement Considerations

Direct substitutes include EA2532XA18-16.000M, which offers tighter ±10 ppm tolerance. Other compatible frequencies in the same package include EA2532QA18-25.000M TR for 25 MHz applications. Verify pin compatibility and electrical parameters before swapping.
