QT216S-48.000MEEQ-T

Overview

The QT216S-48.000MEEQ-T is a quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 48 MHz. It features a compact surface-mount package with dimensions of 2.0 mm x 1.6 mm and a height of 0.7 mm. The component provides a frequency stability of ±10 ppm at 25°C and ±10 ppm over the temperature range of -20°C to +70°C. It utilizes a load capacitance of 10 pF and exhibits an equivalent series resistance (ESR) of 90 Ohms. The device employs a seam-seal construction for environmental protection.

Feature Summary

• Seam-seal construction for enhanced environmental durability
• Compact 2.0x1.6 mm surface-mount footprint
• High frequency stability across specified temperature ranges

Applications

• Precision timing circuits requiring stable clock signals
• Embedded systems utilizing microcontrollers or processors
• Communication modules needing accurate frequency references

Procurement Notes

Verify the manufacturer designation carefully, as similar part numbers may be listed under different brand names such as TXC Corporation in various distributor databases. Ensure the specific suffix matches the required stability and package type. Cross-reference the datasheet provided by the supplier to confirm electrical parameters align with system requirements before finalizing orders.

Selection Notes

Select this component when a small form factor is critical for PCB layout constraints. The 48 MHz frequency is suitable for USB interfaces or general-purpose clocking where moderate precision is sufficient. Consider the 90 Ohm ESR value to ensure compatibility with the driving circuit's oscillation conditions. Verify that the operating temperature range meets the environmental demands of the end application.

Part Context

This part belongs to the QT216S series of quartz crystals, characterized by their small size and seam-seal technology. The series offers various frequency options within a standardized 2.0x1.6 mm package, allowing designers to maintain consistent board layouts while adjusting for different clock speeds. It serves as a direct replacement for other industry-standard crystals in space-constrained designs.

Replacement Considerations

Direct substitutes include the QT216S-48.000MEIQ-T from TXC Corporation, which shares identical electrical specifications and physical dimensions. When replacing, ensure the new component maintains the same load capacitance and frequency tolerance to avoid oscillation issues.
