7M-12.800MAHK-T

Crystals Overview

The 7M-12.800MAHK-T is a quartz crystal oscillator manufactured by TXC Corporation, operating at a fundamental frequency of 12.8 MHz. It features a frequency stability of ±30 ppm at 25°C and ±30 ppm across the -40°C to +85°C temperature range. The component utilizes a 20 pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 3.2 mm x 2.5 mm surface-mount package with four solder pads and no leads, designed for seam seal construction.

Crystals Feature Summary

• Seam seal construction for enhanced environmental protection
• Compact 4-SMD No Lead package design
• Wide industrial temperature range operation

Crystals Applications

• General clock signal generation
• Microcontroller timing circuits
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix and marking code against the official datasheet to ensure compatibility with existing PCB footprints. Confirm that the ±30 ppm stability meets system requirements. Check current availability status as supply levels may vary. Ensure RoHS compliance documentation is obtained prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 12.8 MHz reference is required in a small form factor. The 20 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR value for drive level sensitivity. Verify that the ±30 ppm tolerance is sufficient for the application's jitter and phase noise specifications compared to higher precision alternatives.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series is characterized by standard SMD packages suitable for automated assembly. The 7M-12.800MAHK-T specifically addresses applications needing a stable 12.8 MHz clock source within a constrained board area.

Crystals Replacement Considerations

Direct substitutes include other 12.8 MHz crystals with identical 3.2x2.5mm dimensions, 20pF load capacitance, and ±30ppm stability. Verify pinout compatibility and mounting height constraints before substitution.
