7M-25.000MEEK-T

Crystals Overview

The 7M-25.000MEEK-T is a seam seal MHz quartz crystal manufactured by TXC Corporation, designed for surface mount applications. It operates at a nominal frequency of 25 MHz with a fundamental parallel mode configuration. The component features a compact 3.2 mm x 2.5 mm footprint and a height of approximately 1.0 mm. Key electrical specifications include a frequency tolerance of +/-10 ppm at 25°C and stability of +/-10 ppm over the -20°C to +70°C range. It utilizes a 20 pF load capacitance and is housed in a ceramic package.

Crystals Feature Summary

• Seam seal construction utilizing ceramic packaging for enhanced environmental protection
• Surface mount design optimized for automated PCB assembly processes
• High frequency stability within specified industrial temperature ranges

Crystals Applications

• Reference clocks for portable consumer electronics

Crystals Procurement Notes

Verify the specific suffix MEEK against official datasheets to confirm exact tolerance and temperature range parameters. Ensure compatibility with reflow soldering profiles defined by the manufacturer. Confirm RoHS compliance status through current certification documents prior to integration into production lines.

Crystals Selection Notes

Select this component when a 25 MHz reference with tight initial tolerance is required. The 20 pF load capacitance must match the oscillator circuit design. Consider the 3.2x2.5 mm package size for space-constrained layouts requiring robust seam-sealed performance.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals from TXC Corporation. The series focuses on standard surface mount crystals offering reliable performance for general-purpose timing applications. The 7M designation indicates a specific form factor and sealing technology distinct from other TXC product lines.

Crystals Replacement Considerations

Direct substitutes require matching 25 MHz frequency, 20 pF load capacitance, and +/-10 ppm tolerance. Verify package dimensions and pinout compatibility before substitution.
