EA3250MA18-25.000M TR

Crystals Overview

The EA3250MA18-25.000M TR is a quartz crystal resonator manufactured by Ecliptek, operating at a nominal frequency of 25 MHz. It features an equivalent series resistance (ESR) of 40 Ohms maximum and a load capacitance of 18 pF. The component exhibits a frequency tolerance and stability of ±15 ppm. Designed for surface-mount applications, it utilizes a compact 4-SMD, no lead package with dimensions of 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. The device supports soldering via SMD/SMT termination types.

Crystals Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• High-frequency stability ensuring reliable clock signal generation
• Low equivalent series resistance for efficient circuit operation

Crystals Applications

• Microcontroller clock source integration
• Communication interface timing circuits
• Digital logic system synchronization

Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to assembly. Ensure the 18 pF load capacitance matches the target oscillator circuit requirements to maintain specified frequency accuracy. Check current lifecycle status as components may be subject to discontinuation notices.

Crystals Selection Notes

Select this component for applications requiring precise 25 MHz timing within a small footprint. The 40 Ohm ESR specification must align with the driving circuit's capability to sustain oscillation. Consider the -40°C to +85°C operating temperature range against environmental conditions. The 18 pF load capacitance is critical for matching external circuit parameters to achieve the stated ±15 ppm stability.

Crystals Part Context

This part belongs to the EA3250 series of surface-mount crystals from Ecliptek. It represents a standard solution for general-purpose timing needs where moderate stability and low profile are prioritized. The series offers various frequency options within the same mechanical envelope, allowing for design flexibility across different product lines while maintaining consistent assembly processes.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals in the 3.2x2.5mm package with 18pF load capacitance and similar ESR limits. Verify that alternative parts meet the same ±15 ppm stability requirement and operate within the specified temperature range. Ensure pin compatibility and mounting dimensions match the existing PCB footprint to avoid rework.
