QT161S-32.000MEHQ-T

Overview

The QT161S-32.000MEHQ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 32.000 MHz. It utilizes a surface-mount package with dimensions of 1.6 x 1.2 mm and a height of 0.35 mm. The component features four solder pads with no lead construction. Frequency stability is rated at ±10 ppm from -20°C to +70°C and ±30 ppm from -30°C to +85°C. The load capacitance is specified as 10 pF, and the equivalent series resistance (ESR) is 80 Ohms.

Feature Summary

• Seam seal ceramic construction for reliable operation
• Surface-mount design with four-pad no-lead configuration
• High frequency stability across industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix 'MEHQ' against official QST documentation to confirm the exact temperature range and stability ratings. Ensure the required load capacitance matches the circuit design. Confirm package compatibility with PCB footprint specifications before ordering.

Selection Notes

Select this component when a compact 1.6x1.2 mm crystal is required for 32 MHz applications. Consider the ±10 ppm stability requirement for the primary operating range. Evaluate the 80 Ohm ESR against the oscillator circuit's drive level constraints to ensure proper startup and sustained oscillation.

Part Context

This part belongs to the QT161S series of seam seal crystals from QST. The series offers various frequency options and stability grades. The specific model denotes a 32 MHz unit with defined thermal performance characteristics suitable for standard electronic assemblies requiring precise timing signals.

Replacement Considerations

Direct substitutes include other 32 MHz crystals in 1612 packages with matching 10pF load capacitance and similar ESR values. Verify that alternative parts meet the same ±10 ppm stability specification over the required temperature range.
