QT252S-16.000MEIV-T

Overview

The QT252S-16.000MEIV-T is a surface-mount quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 16.000 MHz and utilizes a seam-sealed metal package with dimensions of 2.50mm x 2.00mm x 0.55mm. The component features a load capacitance of 8pF and offers a frequency stability of ±10ppm at 25°C, extending to ±20ppm across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Seam-sealed metal housing for enhanced environmental protection
• Industrial-grade temperature stability from -40°C to +85°C
• Compact 2.5x2.0mm surface-mount footprint

Applications

• Microcontroller clock sources
• Communication module timing
• Embedded system oscillators

Procurement Notes

Verify the specific suffix MEIV-T against official QST documentation to confirm the exact stability specifications and temperature range. Ensure compatibility with the target circuit's load capacitance requirements, as variations in suffixes may alter electrical parameters. Cross-reference the manufacturer's latest datasheet to validate availability status and any recent design changes before finalizing procurement orders.

Selection Notes

Select this component when a compact, high-stability crystal is required for industrial applications. The 16MHz frequency suits common processor clock speeds. Consider the ±20ppm total stability over temperature for systems requiring precise timing without external compensation. The small form factor aids in dense PCB layouts where space is constrained.
