8Q-25.000MAAJ-T

Crystals Overview

The 8Q-25.000MAAJ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation. It operates at a fundamental frequency of 25 MHz with a load capacitance of 18 pF. The component features a compact 4-pin SMD package measuring 1.6 mm by 1.2 mm, utilizing seam seal technology for environmental protection. Frequency tolerance and stability are specified at ±30 ppm at 25°C and over the operating temperature range of -20°C to +70°C. Equivalent series resistance (ESR) is 100 Ohms, and the drive level is maintained at 10 uW.

Crystals Feature Summary

• Utilizes seam seal construction for enhanced environmental durability
• Provides stable fundamental frequency oscillation at 25 MHz
• Designed for surface mount assembly in compact footprints

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Consumer electronic device synchronization

Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration. Confirm that the thermal profile during soldering aligns with the manufacturer's recommendations for seam seal components. Ensure the circuit design supports the required load capacitance to maintain the specified frequency accuracy within the operational temperature range.

Crystals Selection Notes

Select this component when a small form factor is critical for the layout. The ±30 ppm stability is suitable for standard digital interfaces. Consider the -20°C to +70°C range against application requirements; wider ranges may require alternative series. Verify ESR compatibility with the oscillator circuit to ensure reliable startup.

Crystals Part Context

This part belongs to the 8Q series of MHz quartz crystals from TXC Corporation. The series focuses on miniaturized solutions using seam seal technology. These components are designed to replace larger through-hole or older surface mount packages while maintaining similar electrical performance characteristics for standard clock applications.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 18 pF load capacitance, and 1.6x1.2 mm footprint. Verify equivalent ESR and stability ratings. Cross-reference with other TXC series such as 7R or 7V if dimensional constraints allow.
