7A-8.000MAAJ-T

Crystals Overview

The TXC Corporation 7A-8.000MAAJ-T is a surface-mount quartz crystal unit designed for precision timing applications. It operates at a fundamental frequency of 8 MHz with a standard tolerance and stability of ±30 ppm. The component features an 18 pF load capacitance and utilizes SMD/SMT termination for automated assembly. It is housed in a compact 5 mm x 3.2 mm package, suitable for space-constrained circuit designs.

Crystals Feature Summary

• Glass-sealed construction provides enhanced resistance to moisture and environmental stress compared to standard ceramic packages.
• Optimized for SMT processes, ensuring compatibility with standard reflow soldering profiles and high production yield.
• Low equivalent series resistance (ESR) supports efficient oscillator circuit design with minimal power consumption.

Crystals Applications

• Portable USB data acquisition cards
• Personal Digital Assistants (PDAs)
• Digital cameras
• NFC readers

Crystals Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact electrical parameters and packaging specifications. Ensure that the selected variant meets the required frequency tolerance and load capacitance for the target application circuit before finalizing procurement orders.

Crystals Selection Notes

Select this component when a robust glass-sealed crystal is required for 8 MHz clock generation in portable or industrial electronics. The 5x3.2 mm footprint offers a balance between size and performance, while the ±30 ppm stability ensures reliable operation across typical commercial temperature ranges without complex compensation.

Crystals Part Context

This part belongs to the TXC 7A series, which specializes in 5x3.2 mm glass-sealed quartz crystals. The series is engineered to address reliability issues found in resin or ceramic packages, particularly regarding thermal cycling and humidity exposure, making it a preferred choice for demanding consumer and industrial devices.

Crystals Replacement Considerations

Direct substitutes within the same series include the 7A-12.000MAAJ-T and 7A-24.000MAAJ-T, which share identical physical dimensions and sealing technology but operate at different frequencies. Verify pinout and electrical characteristics before cross-referencing with other manufacturers' offerings.
