7M-25.000MAHK-T

Crystals Overview

The 7M-25.000MAHK-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for commercial applications. It operates at a fundamental frequency of 25 MHz with a frequency tolerance and stability of ±30 ppm across the specified temperature range. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no lead package configuration measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. The unit weighs approximately 16 mg and supports SMD/SMT mounting styles.

Crystals Feature Summary

• Seam seal construction utilizing ceramic materials for structural integrity
• Surface-mount design compatible with automated assembly processes
• Frequency stability maintained within specified limits over operating temperatures

Crystals Applications

• Commercial electronic circuit timing references
• Microcontroller clock source generation
• General-purpose digital signal processing synchronization

Crystals Procurement Notes

Verify the specific suffix HK against official TXC documentation to confirm exact load capacitance and tolerance specifications, as suffix variations often denote distinct electrical parameters. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements. Confirm RoHS compliance status through current manufacturer declarations prior to integration into final assemblies.

Crystals Selection Notes

Select this component when a 25 MHz reference with ±30 ppm stability is required for commercial-grade environments. The 20 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR value for drive level sensitivity. The 3.2x2.5 mm package size offers space efficiency compared to larger through-hole alternatives while maintaining standard mounting compatibility.

Crystals Part Context

This part belongs to the 7M series of seam seal crystals from TXC Corporation. The series typically employs ceramic housings for durability. The 7M designation generally indicates a standard commercial grade product line. Variations within the series differ primarily in frequency, load capacitance, and tolerance specifications defined by alphanumeric suffixes.

Crystals Replacement Considerations

Cross-reference with other 25 MHz crystals featuring 20 pF load capacitance and similar physical dimensions. Verify that substitute components meet the same ±30 ppm stability and 60 Ohm ESR requirements. Ensure the replacement maintains the 4-SMD no lead package format for direct board compatibility.
