7A-32.000MAAQ-T

Crystals Overview

The TXC Corporation 7A-32.000MAAQ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 32.000 MHz. It utilizes a glass-sealed package with dimensions of 5.0 mm x 3.2 mm and features two solder pads. The component exhibits a frequency tolerance of ±30 ppm at 25°C and maintains stability within ±30 ppm across the commercial temperature range of -20°C to +70°C. It is designed for a load capacitance of 10 pF.

Crystals Feature Summary

• Glass-sealed construction provides enhanced environmental protection against moisture and contaminants compared to standard ceramic packages.

Crystals Applications

• Portable USB interface cards
• Personal Digital Assistants (PDAs)
• Digital cameras

Crystals Procurement Notes

Verify the specific suffix 'AAQ' to confirm the 10 pF load capacitance requirement, as other variants in the 7A series may utilize different capacitance values such as 18 pF. Ensure the design accommodates the 5x3.2 mm footprint and that the PCB layout supports the two-pad SMD configuration. Confirm compliance with RoHS directives, noting that lead content in the glass seal may fall under specific exemptions depending on regional regulations.

Crystals Selection Notes

Select this component when a compact 3225 form factor is required alongside superior long-term stability and environmental resistance compared to resin-packaged alternatives. It is suitable for applications where thermal cycling reliability is critical. Consider alternative part numbers if a higher frequency tolerance or industrial temperature range is necessary, as this model is optimized for commercial grade performance.

Crystals Part Context

This part belongs to the TXC 7A series, which specializes in glass-sealed quartz crystals. The series is engineered to address frequency drift issues common in standard ceramic packages during reflow soldering and harsh environmental conditions. The 7A series offers improved aging characteristics and mechanical robustness for consumer electronics and portable devices.
