QT216S-48.000MAHV-T

Overview

The QT216S-48.000MAHV-T is a surface-mount quartz crystal resonator manufactured by QST. It operates at a fundamental frequency of 48.000 MHz with a load capacitance of 8 pF and an equivalent series resistance of 50 Ohms. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C, extending to ±30 ppm over the operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, no-lead package with dimensions of 2.0 mm x 1.6 mm.

Feature Summary

• Compact 2.0x1.6 mm surface-mount footprint for space-constrained designs
• High frequency stability of ±30 ppm across wide industrial temperature ranges
• Low equivalent series resistance of 50 Ohms for efficient circuit integration

Applications

• Precision timing circuits in consumer electronics
• Clock generation for microcontrollers and digital signal processors
• Communication modules requiring stable carrier frequencies

Procurement Notes

Verify the specific suffix HV against official QST documentation to confirm exact temperature range and tolerance specifications. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm that the 8 pF load capacitance matches the oscillator circuit requirements. Check for RoHS compliance status if required by project standards.

Selection Notes

Select this component when a 48 MHz reference is needed in a minimal SMD form factor. The ±30 ppm stability suits general-purpose timing applications rather than high-precision RF systems. Consider the 50 Ohm ESR limit to ensure proper oscillation startup conditions within the target circuit design constraints.

Part Context

This part belongs to the QT216S series of thin-film or bulk acoustic wave crystals designed for surface mount technology. The series offers various frequency options within the same mechanical envelope, allowing for standardized PCB layouts across different product variants while maintaining consistent electrical interface characteristics.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 8 pF load capacitance, 4-SMD no-lead package, and ±30 ppm stability. Verify thermal performance limits align with the -40°C to +85°C range. Cross-reference ESR values to ensure circuit compatibility.
