QT252S-54.000METE-T

Overview

The QT252S-54.000METE-T is a quartz crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 54.000 MHz and utilizes a 2.5x2.0 mm surface-mount package with a height of approximately 0.55 mm. The component features a load capacitance of 10 pF and offers high frequency stability with tolerances of ±10 ppm at 25°C and ±10 ppm across the -30°C to +85°C operating temperature range. It is designed for seam seal construction.

Feature Summary

• Seam seal construction for enhanced environmental protection
• High frequency stability within ±10 ppm tolerance
• Wide operating temperature range from -30°C to +85°C
• Compact 2.5x2.0 mm surface-mount footprint

Applications

• Clock generation for high-speed digital circuits
• Communication equipment requiring precise timing
• Consumer electronics with space constraints
• Industrial control systems operating in varied temperatures

Procurement Notes

Verify manufacturer authenticity through official QST channels or authorized distributors. Confirm RoHS compliance status and lead-free specifications against current regulatory requirements. Ensure storage conditions maintain component integrity prior to assembly. Cross-reference datasheet revisions to confirm parameter consistency.

Selection Notes

Select this component when a 54 MHz reference signal is required with tight stability constraints. The 10 pF load capacitance must match the oscillator circuit design. Consider the -30°C to +85°C range for industrial applications. Verify package dimensions fit PCB layout constraints.

Part Context

This part belongs to the QT252S series of surface-mount quartz crystals. The series offers various frequencies and stability options in a standardized small outline package. It serves as a timing reference for microcontrollers, processors, and communication interfaces requiring stable clock signals.

Replacement Considerations

Compatible substitutes include other 54 MHz crystals with identical 2.5x2.0 mm packages and ±10 ppm stability. Verify load capacitance matches 10 pF. Check temperature range compatibility. Examples: QT252S-54.000MEEQ-T variants.
