QT161S-24.000MEIV-T

Overview

The QT161S-24.000MEIV-T is a surface-mount quartz crystal resonator manufactured by QST, designed for precision timing applications in compact electronic circuits. It operates at a fundamental frequency of 24 MHz with a physical footprint of 1.6 mm x 1.2 mm x 0.35 mm. The component features a load capacitance of 8 pF and offers a frequency tolerance of ±10 ppm at 25°C. Frequency stability is rated at ±20 ppm over an extended operating temperature range of -40°C to +85°C. This SMD package utilizes a ceramic construction suitable for automated assembly processes.

Feature Summary

• Compact 1.6x1.2 mm surface-mount design for space-constrained PCB layouts
• High frequency stability of ±20 ppm across wide industrial temperature ranges
• Precision 24 MHz output with tight initial tolerance specifications

Applications

• Microcontroller clock sources in embedded systems
• Communication module timing references
• Consumer electronics requiring precise synchronization

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with QST rather than TXC Corporation. Confirm that the 8 pF load capacitance matches your circuit design requirements, as other variants may use different values. Ensure the -40°C to +85°C temperature range aligns with your operational environment constraints before finalizing procurement decisions.

Selection Notes

Select this component when a small form factor is critical alongside stable 24 MHz performance. The 8 pF load capacitance requires matching oscillator circuit parameters to ensure accurate frequency generation. Consider the wider temperature stability compared to commercial grade parts if the application involves variable environmental conditions or strict timing accuracy requirements.

Part Context

This quartz crystal belongs to the QT161S series, characterized by its slim profile and seam-seal construction. It serves as a standard timing element for digital logic and microprocessor applications. The series provides reliable oscillation characteristics while maintaining low power consumption and high reliability standards typical of modern surface-mount resonators.

Replacement Considerations

Direct substitutes include the QT161S-24.000MEEQ-T from TXC Corporation, though verification of load capacitance differences is required. Other compatible options must match the 1.6x1.2 mm footprint, 24 MHz frequency, and 8 pF load capacitance specifications to ensure electrical compatibility.
