7M-16.000MAHC-T

Crystals Overview

The 7M-16.000MAHC-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 16 MHz. It features a load capacitance of 9 pF and offers a frequency tolerance and stability of ±30 ppm. The component utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.7mm. It exhibits an equivalent series resistance (ESR) of 80 Ohms and supports base harmonic operation.

Crystals Feature Summary

• Compact 3.2mm x 2.5mm SMD footprint for space-constrained designs
• High precision frequency stability within ±30 ppm tolerance
• Seam sealing construction for enhanced environmental reliability

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix 'HC' against official datasheets to confirm the 9pF load capacitance specification, as variations exist within the 7M series. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages. Confirm RoHS3 compliance status prior to integration into regulated assemblies.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency accuracy. The 9pF load capacitance necessitates circuit design adjustments compared to 12pF alternatives. Consider the 80 Ohm ESR value for oscillator circuit stability margins during initial schematic design phases.

Crystals Part Context

This part belongs to the TXC 7M series of seam-sealed crystals, designed for high-frequency stability in compact applications. It serves as a fundamental mode resonator, distinct from higher-capacitance variants like the 7M-16.000MAHE-T which uses 12pF. The series emphasizes miniaturization without compromising basic timing performance.

Crystals Replacement Considerations

The 7M-16.000MAHC-T is listed as obsolete. Public confirmed substitutes include the 7M-16.000MAHE-T, though it differs in load capacitance (12pF vs 9pF). Verify circuit compatibility before substitution.
