7V-12.288MDHQ-T

Crystals Overview

The 7V-12.288MDHQ-T is a MHz quartz crystal oscillator manufactured by TXC Corporation, housed in a compact 3.2x2.5 mm surface-mount package with glass seal technology. It operates at a nominal frequency of 12.288 MHz with a load capacitance of 10 pF. The component provides high frequency stability, maintaining a tolerance of +/-20 ppm at 25°C and +/-30 ppm across the industrial temperature range of -40°C to +85°C. Designed for reliable performance in space-constrained applications, it utilizes ceramic construction and four-pad SMD termination.

Crystals Feature Summary

• Glass-sealed construction ensures long-term stability and environmental protection
• Compact 3.2x2.5 mm footprint suitable for dense PCB layouts
• High frequency accuracy with tight tolerance specifications

Crystals Applications

• Consumer electronics requiring precise timing references
• Industrial control systems operating in varied temperatures
• Communication modules needing stable clock signals

Crystals Procurement Notes

Verify the specific suffix 'HQ' against official TXC documentation to confirm the 10pF load capacitance and +/-20ppm initial tolerance, as these parameters distinguish this variant from other 7V series models. Ensure compatibility with your circuit's load capacitance requirements before integration.

Crystals Selection Notes

Select this component when a small form factor is critical alongside high stability. The 10pF load capacitance requires careful PCB layout to match total stray capacitance. Consider the -40°C to +85°C range for industrial environments where standard commercial grades may fail.

Crystals Part Context

This part belongs to the 7V series of MHz quartz crystals from TXC Corporation. These components are designed for general-purpose timing applications, offering a balance between size, cost, and performance. The series is widely used in portable devices and embedded systems where space is limited but reliability is paramount.

Crystals Replacement Considerations

Direct substitutes must match the 3.2x2.5mm package, 12.288MHz frequency, 10pF load capacitance, and +/-30ppm over-temperature stability. Verify that alternative manufacturers offer equivalent glass-seal or ceramic packages to maintain similar environmental robustness.
