QT161S-24.000MDDV-T

Overview

The QT161S-24.000MDDV-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation and distributed by QST. It operates at a fundamental frequency of 24 MHz with a load capacitance of 8 pF. The component features a compact 1.6 x 1.2 mm package size and offers a frequency stability of ±20 ppm across the commercial temperature range of -20°C to +70°C. It utilizes a seam seal construction with four solder pads for reliable SMD attachment.

Feature Summary

• Compact 1.6x1.2 mm surface mount footprint
• Seam seal ceramic construction
• Four-pad SMD termination

Applications

• Embedded communication systems
• Signal acquisition platforms
• Microcontroller clock sources

Procurement Notes

Verify the manufacturer designation, as this part is produced by TXC Corporation but sold under QST distribution channels. Confirm the specific suffix 'MDDV' matches the required 8pF load capacitance and ±20ppm stability specifications. Ensure the 1.6x1.2mm package dimensions align with your PCB layout constraints before finalizing orders.

Selection Notes

Select this component when a small form factor is critical for space-constrained designs requiring 24 MHz timing. The ±20ppm stability suits general-purpose digital circuits where tighter precision is unnecessary. Compare against the MEEQ variant if 10ppm stability or 10pF load capacitance is required instead.

Part Context

This part belongs to the QT161S series of low-profile quartz crystals. It shares the same physical dimensions and basic electrical characteristics with other variants in the family, differing primarily in frequency, load capacitance, and stability ratings. It serves as a standard timing element for consumer electronics and industrial control boards.

Replacement Considerations

Direct substitutes include the QT161S-24.000MEEQ-T for higher stability applications. Other compatible alternatives within the same package size may be found by matching the 24 MHz frequency, 8pF load capacitance, and 1.6x1.2mm outline.
