QT161S-24.000MEEQ-T

Overview

The QT161S-24.000MEEQ-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, distributed under the QST brand. It operates at a nominal frequency of 24 MHz with a load capacitance of 10 pF. The component features a compact 1.6x1.2 mm body size and utilizes a four-pad no-lead SMD package. Frequency stability is rated at ±10 ppm at 25°C and ±10 ppm over the operating temperature range of -20°C to +70°C. Resonator tolerance matches the stability specification at ±10 ppm.

Feature Summary

• Seam seal ceramic construction for environmental durability
• Compact 1.6x1.2 mm footprint suitable for space-constrained designs
• High frequency stability across standard industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing
• Digital signal processing circuits

Procurement Notes

Verify manufacturer designation as TXC Corporation when sourcing from distributors like QST or Mouser. Confirm the specific suffix 'E' indicates ±10 ppm stability within the -20°C to +70°C range. Ensure compatibility with 10 pF load capacitance requirements in the target circuit design before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise 24 MHz timing in small form factors. The ±10 ppm stability ensures reliable synchronization for digital interfaces. Consider thermal performance if operating near the upper limit of the specified temperature range. Verify that the PCB layout supports the four-pad no-lead package geometry for optimal solder joint integrity.

Part Context

This part belongs to the QT161S series of seam seal crystals. The series offers various frequency options and stability grades. The 'E' suffix specifically denotes the ±10 ppm stability class for the -20°C to +70°C range. Other suffixes indicate different tolerances or extended temperature capabilities within the same physical package family.

Replacement Considerations

Direct substitutes include other 24 MHz crystals with identical 1.6x1.2 mm dimensions and 10 pF load capacitance. Check datasheets for equivalent stability ratings of ±10 ppm. Ensure the replacement maintains the four-pad no-lead SMD configuration to fit existing footprints without rework.
