7M-12.800MEIK-T

Crystals Overview

The TXC CORPORATION 7M-12.800MEIK-T is a high-accuracy quartz crystal resonator designed for surface mount applications. It operates at a fundamental frequency of 12.8 MHz with a tolerance of ±10 ppm and a load capacitance of 20 pF. The component features an equivalent series resistance (ESR) of 80 Ohms and supports a maximum drive level of 100 µW. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm x 0.7 mm. The device ensures reliable performance across an extended industrial temperature range from -40°C to +85°C.

Crystals Feature Summary

• High frequency stability with ±10 ppm tolerance
• Wide operating temperature range for industrial environments
• Compact surface-mount footprint for automated assembly

Crystals Applications

• Precision timing circuits in communication systems
• Clock generation for microprocessors and digital logic

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the 20 pF load capacitance requirement matches the target circuit design to ensure accurate frequency operation. Ensure the selected variant meets the required ±10 ppm tolerance specification for the intended application environment.

Crystals Selection Notes

Select this component when a precise 12.8 MHz reference is required within a limited board space. The 4-SMD package facilitates efficient placement during manufacturing processes. Consider the 80 Ohm ESR value to ensure compatibility with the oscillator circuit's driving requirements. Verify that the 100 µW drive level limit aligns with the host system's power constraints.

Crystals Part Context

This part belongs to the 7M series of high-accuracy MHz crystals manufactured by TXC Corporation. The series is characterized by its small physical dimensions and robust performance across varying thermal conditions. It serves as a critical timing element in modern electronic designs where size and precision are paramount.

Crystals Replacement Considerations

Substitutes must match the 12.8 MHz frequency, 20 pF load capacitance, and 4-SMD package dimensions. Verify that alternative parts support the same ±10 ppm tolerance and -40°C to +85°C operating range.
