9C-8.000MAAS-T

Crystals Overview

The 9C-8.000MAAS-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 8 MHz with a load capacitance of 30 pF and a series resistance of 80 Ohms. The component features a frequency tolerance and stability of ±30 ppm, ensuring reliable timing performance. It utilizes the HC-49/US package format and supports fundamental operating mode. The device functions within an ambient temperature range of -20°C to +70°C, making it suitable for standard commercial applications requiring stable clock signals.

Crystals Feature Summary

• Surface mount construction in HC-49/US package
• Fundamental oscillation mode operation
• ±30 ppm frequency stability specification
• Designed for 30 pF load capacitance environments

Crystals Applications

• General purpose digital circuit timing
• Microcontroller clock sources
• Communication interface synchronization
• Consumer electronics timekeeping modules

Crystals Procurement Notes

Verify that the specific suffix 'MAAS' corresponds to the 30 pF load capacitance variant, as other suffixes in the 9C series may indicate different capacitance values such as 18 pF or 12.5 pF. Confirm the HC-49/US package dimensions match the PCB footprint requirements. Ensure the ±30 ppm stability meets the system timing budget. Check for RoHS compliance status if required by project specifications. Validate the active lifecycle status directly with the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a standard 8 MHz reference is needed with moderate stability requirements. The HC-49/US SMD form factor offers a balance between size and mechanical robustness compared to smaller packages. Consider the 30 pF load capacitance requirement carefully to ensure compatibility with the oscillator circuit design. The -20°C to +70°C temperature range is appropriate for general indoor consumer devices rather than harsh industrial or automotive environments.

Crystals Part Context

The 9C series represents TXC Corporation's line of surface-mount crystals utilizing the traditional HC-49/US footprint adapted for SMD assembly. This series provides a cost-effective solution for mass-produced electronics where space constraints are less severe than in ultra-compact mobile devices. The 9C-8.000MAAS-T specifically targets the common 8 MHz frequency point used in various microprocessor and communication systems.

Crystals Replacement Considerations

Direct substitutes include the 9C-8.000MAAJ-T, though verification of the load capacitance difference (18 pF vs 30 pF) is mandatory. Other 8 MHz SMD crystals from TXC in similar packages should be evaluated for identical electrical parameters. Cross-referencing datasheets is essential to confirm matching series resistance and drive level specifications.
