QT216S-52.000MEIE-T

Overview

The QT216S-52.000MEIE-T is a quartz crystal resonator manufactured by QST, designed for precision timing applications in electronic circuits. This component operates at a fundamental frequency of 52 MHz and utilizes a surface-mount package configuration. It features a load capacitance specification of 10 pF and an equivalent series resistance (ESR) typically rated at 90 Ohms. The device provides a frequency stability of ±10 ppm over the specified operating temperature range. The part number suffix indicates specific terminal plating and packaging options consistent with QST's standard SMD crystal lineup.

Feature Summary

• Provides stable oscillation at 52 MHz for clock generation
• Compact surface-mount design suitable for automated assembly
• Ensures precise timing accuracy within tight tolerance limits

Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing systems

Procurement Notes

Verify the exact suffix MEIE against official QST documentation to confirm terminal finish and reel specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Cross-reference the load capacitance requirements of the host oscillator circuit to maintain frequency accuracy. Confirm that the operating temperature range meets the environmental constraints of the final application.

Selection Notes

Select this component when a 52 MHz reference is required with ±10 ppm stability. Consider the 10 pF load capacitance requirement for circuit matching. Evaluate the 4-SMD no-lead package dimensions for PCB layout constraints. Compare ESR values against oscillator driver strength capabilities to ensure reliable startup conditions.

Part Context

This crystal belongs to QST's QT216S series of general-purpose surface-mount crystals. The series offers various frequencies and package options for consumer and industrial electronics. It serves as a foundational timing element for digital systems requiring stable clock signals without the complexity of active oscillators.

Replacement Considerations

Direct substitutes include other 52 MHz ±10 ppm crystals in identical 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as ESR and load capacitance before substitution.
