QT216S-48.000MEIV-T

Overview

The QT216S-48.000MEIV-T is a surface-mount crystal oscillator manufactured by QST, designed for embedded systems requiring precise timing. It operates at a nominal frequency of 48 MHz with a standard load capacitance of 8 pF. The component features a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm and a maximum height of 0.50 mm. Frequency stability is specified at ±10 ppm at 25°C and ±20 ppm over the temperature range of -40°C to +85°C. This quartz crystal provides reliable clock signals for digital circuits.

Feature Summary

• Compact 2.0 x 1.6 mm surface-mount footprint suitable for space-constrained designs
• High frequency stability with ±10 ppm tolerance at room temperature
• Wide operating temperature range from -40°C to +85°C for industrial reliability
• Lead-free construction compliant with RoHS3 standards

Applications

• Embedded communication systems requiring stable clock sources
• Microcontroller-based digital circuitry
• Industrial control cabinets and automation equipment
• Consumer electronics utilizing 48 MHz timing references

Procurement Notes

Verify the specific suffix MEIV against official QST documentation to confirm the exact temperature stability specifications and packaging details. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference the part number with authorized distributors to confirm authenticity and current manufacturing status before procurement.

Selection Notes

Select this component when a 48 MHz reference is required with tight stability constraints in a small form factor. The ±10 ppm accuracy at 25°C makes it suitable for applications where ceramic resonators lack sufficient precision. Consider the 8 pF load capacitance requirement for circuit design matching.

Part Context

This part belongs to the QT216S series of quartz crystals from QST, which are characterized by their small SMD packages and high stability. The series supports various frequencies and stability grades, catering to mainstream embedded system needs where size and performance balance is critical.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 8 pF load capacitance, and 2.0x1.6mm package dimensions. Verify equivalent stability ratings (±10 ppm/±20 ppm) and operating temperature ranges from alternative manufacturers to ensure functional parity.
