QT252S-20.000MEEV-T

Overview

The QT252S-20.000MEEV-T is a quartz crystal resonator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 8 pF. The component features a surface-mount package measuring 2.5 mm by 2.0 mm in footprint. Frequency tolerance is specified at ±10 ppm at 25°C and ±10 ppm across the industrial temperature range of -20°C to +70°C. The device utilizes a seam seal construction to ensure environmental stability and long-term reliability.

Feature Summary

• High frequency accuracy with ±10 ppm tolerance at room temperature
• Compact 2.5x2.0 mm surface-mount form factor
• Seam seal construction for enhanced environmental protection
• Designed for stable operation within the -20°C to +70°C temperature range

Applications

• Microcontroller clock sources
• Communication module timing references
• Portable electronic devices requiring precise synchronization
• Industrial control systems

Procurement Notes

Verify the manufacturer part number QT252S-20.000MEEV-T against official QST documentation to confirm specifications. Ensure compatibility with the target circuit's load capacitance requirements of 8 pF. Check for RoHS compliance status if required by project standards. Confirm availability through authorized distributors as supply conditions may vary.

Selection Notes

Select this component when a small footprint and high stability are required for 20 MHz applications. The ±10 ppm tolerance suits most digital logic interfaces. Consider the operating temperature range limits for deployment in harsh environments. Compare against other series members for alternative package sizes or frequency options if needed.

Part Context

This part belongs to the QT252S series of quartz crystals from QST. The series offers various frequencies and tolerances in a standardized 2.5x2.0 mm package. These components are engineered for consumer electronics and industrial equipment where space constraints and timing precision are critical design factors.

Replacement Considerations

Compatible substitutes include other 20 MHz crystals with identical 2.5x2.0 mm packages and 8 pF load capacitance. Verify that alternative parts meet the same ±10 ppm tolerance and temperature range specifications before integration.
