7M-12.800MEIQ-T

Crystals Overview

The 7M-12.800MEIQ-T is a high-precision quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 12.8 MHz. It features a frequency tolerance and stability of ±10 ppm within an operating temperature range of -40°C to +85°C. The component utilizes a 10 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 80 Ohms. Designed for surface-mount applications, it is housed in a compact 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm.

Crystals Feature Summary

• High precision frequency stability of ±10 ppm across the industrial temperature range
• Ultra-miniature 3.2mm x 2.5mm surface-mount footprint for space-constrained designs
• Low equivalent series resistance (ESR) of 80 Ohms for efficient circuit operation

Crystals Applications

• Precision clock signal generation in embedded systems
• Synchronization circuits in communication modules
• Microcontroller and processor system clocks requiring stable timing references

Crystals Procurement Notes

Verify the specific suffix 'MEIQ' against the manufacturer's current datasheet to confirm pin configuration and material specifications. Ensure the selected variant matches the required load capacitance of 10 pF for the target oscillator circuit design. Cross-reference the package outline drawing to validate PCB footprint compatibility before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12.8 MHz reference with ±10 ppm stability is required in a small form factor. Compare the 80 Ohm ESR limit against the oscillator driver strength to ensure reliable startup. Consider the -40°C to +85°C rating for industrial environments. Evaluate alternative packages if board space allows for different mounting requirements.

Crystals Part Context

This part belongs to the 7M Series from TXC Corporation, which specializes in ultra-miniature, thin quartz crystals. The series is characterized by high accuracy, extremely low aging, and high Q-factor performance. These components are engineered for modern electronics demanding precise timing in minimal physical spaces.

Crystals Replacement Considerations

Direct substitutes must match the 12.8 MHz frequency, ±10 ppm stability, 10 pF load capacitance, and 3.2x2.5mm SMD package. Verify that any replacement maintains the same ESR characteristics and temperature range to ensure circuit compatibility.
