QT216S-80.000METV-T

Overview

The QT216S-80.000METV-T is a surface-mount crystal oscillator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 80.000 MHz with a frequency tolerance of ±10 ppm at 25°C and ±10 ppm over the temperature range of -30°C to +85°C. The component utilizes a compact 4-SMD, No Lead package measuring 2.0 mm by 1.6 mm. It features a load capacitance of 8 pF, ensuring compatibility with standard oscillator circuits. This device provides stable clock signals for digital systems requiring high accuracy within a minimal footprint.

Feature Summary

• Compact 2.0x1.6 mm surface-mount package for space-constrained designs
• High frequency stability with ±10 ppm tolerance across specified temperature ranges
• Optimized for 8 pF load capacitance integration
• Lead-free construction compliant with environmental standards

Applications

• Clock generation for microcontrollers and processors
• Timing references in communication modules
• Precision timing circuits in consumer electronics
• Embedded system clock sources

Procurement Notes

Verify the specific suffix METV-T against MEEV-T to confirm the operating temperature range, as METV-T specifies -30°C to +85°C while other variants may differ. Ensure the load capacitance requirement of 8 pF matches the target circuit design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a small form factor is critical alongside precise 80 MHz timing. The ±10 ppm tolerance suits applications where moderate frequency drift is acceptable. Consider the 8 pF load capacitance requirement during PCB layout to ensure accurate frequency performance. Evaluate thermal requirements to ensure the -30°C to +85°C range meets the operational environment constraints.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST. The series offers various frequency options and package sizes. The METV-T suffix indicates specific temperature and packaging characteristics. It serves as a fundamental frequency reference component in modern electronic assemblies requiring reliable clock signals.

Replacement Considerations

QT216S-80.000MEEV-T is a related variant but may have different temperature specifications (-20°C to +70°C typically). Verify exact electrical parameters and temperature ranges before substitution. Direct pin-compatible replacements must match the 80 MHz frequency, 8 pF load capacitance, and 2.0x1.6 mm package dimensions.
