QT216S-50.000MEIV-T

Overview

The QT216S-50.000MEIV-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 50 MHz. It features a fundamental operating mode and utilizes an 8 pF load capacitance. The component exhibits a frequency tolerance of ±10 ppm at 25°C and a stability range of ±20 ppm across the -40°C to +85°C temperature range. Housed in a compact 2.0x1.6 mm package with a maximum seated height of 0.50 mm, it is designed for precise timing applications requiring high reliability and low profile integration.

Procurement Notes

Verify the complete part number including suffixes against official QST documentation to ensure correct tolerance and packaging specifications. Confirm that the required load capacitance matches the circuit design parameters. Check for any specific handling requirements related to surface-mount components during procurement processes.

Selection Notes

Select this component when a 50 MHz reference with tight initial tolerance is required. Ensure the application environment falls within the specified -40°C to +85°C operational range. Verify that the PCB layout accommodates the 2.0x1.6 mm package dimensions and that the load capacitance aligns with the oscillator circuit requirements.

Part Context

This model belongs to the QT216S series of surface-mount crystals from QST. The series offers various frequency options and tolerance levels tailored for modern electronic designs. The specific MEIV-T suffix denotes the 50 MHz variant with defined stability characteristics suitable for general-purpose timing needs.

Replacement Considerations

Cross-reference with other manufacturers offering 50 MHz SMD crystals in 2.0x1.6 packages. Ensure equivalent electrical parameters such as load capacitance and frequency stability are met before substitution.
