7A-12.000MAAK-T

Crystals Overview

The TXC Corporation 7A-12.000MAAK-T is a surface-mount quartz crystal oscillator operating at a nominal frequency of 12.000 MHz. It features a load capacitance of 20 pF and a frequency tolerance of ±30 ppm. The component utilizes an SMD/SMT package with dimensions of 5 mm x 3.2 mm x 1.2 mm. It supports a standard operating temperature range from -40°C to +85°C. The device is designed for high reliability in compact electronic applications requiring stable clock signals.

Crystals Feature Summary

• Glass-sealed construction provides enhanced resistance to moisture and environmental stress compared to resin or ceramic packages.
• Compatible with standard SMT assembly processes, including automatic placement and reflow soldering.
• RoHS compliant with lead content exempted under directive regulations.

Crystals Applications

• Laptop computers
• Personal Digital Assistants (PDAs)
• Digital cameras
• USB interface cards

Crystals Procurement Notes

Verify the specific suffix 'AAK' against official datasheets to confirm the 20pF load capacitance specification. Ensure compatibility with circuit designs requiring this specific capacitive load rather than the standard 18pF found in similar series variants. Confirm end-of-life status if sourcing from secondary markets.

Crystals Selection Notes

Select this part when a 12 MHz clock source with 20pF load capacitance is required in a 5x3.2mm footprint. It is suitable for general-purpose consumer electronics where ±30ppm stability is sufficient. Consider alternative series if automotive AEC-Q200 certification or tighter frequency tolerances are necessary for the application.

Crystals Part Context

This component belongs to the TXC 7A series of glass-sealed surface-mount crystals. The series is characterized by its robust packaging technology, which offers superior performance in harsh environments compared to traditional ceramic or resin-packaged crystals. The 7A series is widely used in portable and industrial devices.

Crystals Replacement Considerations

The 7A-12.000MAHJ-T is a comparable variant within the same series but specifies an 18pF load capacitance instead of 20pF. Verify circuit compatibility before substitution, as the difference in load capacitance may affect frequency accuracy in sensitive designs.
