QT161S-60.000MEHY-T

Overview

The QT161S-60.000MEHY-T is a surface-mount crystal oscillator manufactured by QST. It operates at a fundamental frequency of 60 MHz with a load capacitance of 8 pF and an equivalent series resistance of 80 Ohms maximum. The device features a ±20 ppm frequency stability over the industrial temperature range of -20°C to +70°C, as indicated by the 'D' suffix in the ordering code. It utilizes a 4-SMD, no lead package design suitable for automated surface mount assembly.

Feature Summary

• Provides precise timing signals via quartz crystal resonance
• Designed for compact surface mount integration
• Ensures stable oscillation within specified thermal limits

Applications

• Digital clock generation circuits
• Microcontroller system clocks
• Communication interface synchronization

Procurement Notes

Verify the specific suffix codes against official QST documentation to confirm exact frequency tolerance and temperature range specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer's datasheet. Confirm that the 4-SMD footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a 60 MHz reference signal is required with moderate stability constraints. The 8 pF load capacitance must align with the host circuit's input capacitance to maintain accurate frequency output. Consider the 80 Ohm ESR limit for drive level sensitivity and power consumption requirements in low-power applications.

Part Context

This part belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequency options and stability grades. The specific model denotes a 60 MHz unit with industrial grade temperature performance. It serves as a passive timing element in electronic assemblies requiring reliable clock sources.

Replacement Considerations

Direct substitutes must match the 60 MHz frequency, 8 pF load capacitance, 4-SMD package, and ±20 ppm stability. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar SMD crystal specifications.
