QT252S-48.000MEEQ-T

Overview

The QT252S-48.000MEEQ-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 48 MHz with a load capacitance of 10 pF. The component features a 4-pad ceramic package with dimensions of 2.5 x 2.0 mm. Frequency stability is specified at ±10 ppm at 25°C and ±10 ppm over the temperature range of -20°C to +70°C. The device utilizes seam seal technology for enhanced environmental protection.

Feature Summary

• Seam seal construction for robust environmental sealing
• Compact 4-pad ceramic surface-mount footprint
• High frequency stability across defined operating temperatures

Applications

• Automotive body electronics and lighting systems
• Industrial control equipment
• Medical devices requiring precise timing
• Personal electronics and consumer gadgets

Procurement Notes

Verify the manufacturer designation on the final datasheet, as similar part numbers in this series are frequently associated with TXC Corporation. Confirm that the specific suffix matches the required stability and temperature range specifications for your design. Ensure compatibility with the 10 pF load capacitance requirement before ordering.

Selection Notes

Select this component when a 48 MHz clock source is required for compact designs. The ±10 ppm stability suits applications needing reliable timing without high-cost oven-controlled oscillators. Consider the 2.5x2.0 mm package size for space-constrained PCB layouts. Verify thermal requirements against the -20°C to +70°C operational range.

Part Context

This part belongs to the QT252S series of seam seal crystals. These components are engineered for general-purpose timing applications where moderate stability and small form factors are prioritized. The series offers various frequency options and stability grades to accommodate different electronic system requirements.

Replacement Considerations

QT252S-48.000MAHE-T (TXC) offers ±30 ppm stability. QT252S-48.000MDDQ-T (TXC) provides ±20 ppm stability. Cross-reference pinout and load capacitance compatibility before substitution.
