QT325S-25.000MEIK-T

Overview

The QT325S-25.000MEIK-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It features a glass-sealed package with dimensions of 3.2mm x 2.5mm and a height of 0.7mm. The component operates at a nominal frequency of 25MHz with a load capacitance of 18pF. Frequency stability is specified as ±10ppm at 25°C and ±20ppm across the industrial temperature range of -40°C to +85°C.

Feature Summary

Glass-sealed construction for environmental protection
Surface-mount design for automated assembly
High frequency stability within specified temperature ranges

Applications

Microcontroller clock sources
Communication module timing circuits
Digital signal processing systems

Procurement Notes

Verify the specific suffix 'IK' against official QST documentation to confirm the exact stability grades and temperature coefficients. Ensure compatibility with reflow soldering profiles defined in the manufacturer datasheet. Cross-reference the load capacitance requirements with the target circuit design to maintain frequency accuracy. Confirm availability through authorized distributors as supply status may vary.

Selection Notes

Select this component when a compact 3.2x2.5mm footprint is required for space-constrained designs. Choose based on the need for tight frequency tolerance of ±10ppm at room temperature. Consider the glass-seal technology for improved reliability compared to ceramic alternatives. Validate that the 18pF load capacitance matches the oscillator circuit specifications.

Part Context

This part belongs to the QT325S series of MHz quartz crystals from QST. The series utilizes seam seal technology for enhanced durability. Variants within the series differ primarily in stability ratings and operating temperature ranges, identified by specific alphanumeric suffixes following the base model number.

Replacement Considerations

Direct substitutes must match the 3.2x2.5mm package, 25MHz frequency, and 18pF load capacitance. Verify that alternative components offer equivalent or superior stability metrics of ±10ppm at 25°C and ±20ppm over the -40°C to +85°C range to ensure system performance consistency.
