QT161S-24.000MAAV-T

Overview

The QT161S-24.000MAAV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 24 MHz with a load capacitance of 8 pF and an equivalent series resistance of 80 Ohms. The component features a compact 4-SMD, No Lead package with dimensions of 1.6 x 1.2 x 0.35 mm. Frequency stability is specified at ±30 ppm at 25°C and ±30 ppm over the temperature range of -20°C to +70°C. The device utilizes a seam seal construction with ceramic packaging.

Feature Summary

• Compact 1.6x1.2mm surface-mount footprint suitable for space-constrained designs
• Seam seal construction ensuring environmental protection
• Stable frequency performance across standard industrial temperature ranges

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with QST in distributor catalogs, while similar model numbers may be produced by TXC Corporation. Confirm the exact load capacitance and tolerance requirements match the circuit design specifications before ordering. Ensure the package type aligns with the PCB footprint requirements.

Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 8 pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm tolerance sufficient for general digital logic timing but verify against stricter requirements if applicable. The low profile height aids in thin device assembly.

Part Context

This component belongs to the QT161S series of quartz crystals, characterized by their small 1.6x1.2 mm SMD package. The series offers various frequency options and tolerance levels, catering to diverse consumer electronics and industrial applications requiring reliable timing signals in minimal space.

Replacement Considerations

QT161S-24.000MEEQ-T from TXC Corporation offers similar dimensions but differs in tolerance (±10 ppm) and load capacitance (10 pF). Direct substitution requires verifying oscillator circuit compatibility with these parameter changes.
