7S-18.432MAAE-T

Crystals Overview

The 7S-18.432MAAE-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 18.432 MHz with a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component supports a wide operating temperature range from -20°C to +70°C and is housed in a compact 2.5 mm x 2.0 mm SMD package.

Crystals Feature Summary

• Compact 2.5x2.0 mm surface-mount footprint suitable for space-constrained designs
• Fundamental mode operation providing stable 18.432 MHz reference signal
• Wide industrial temperature range capability for reliable performance

Crystals Applications

• Digital clock generation circuits
• Microcontroller system timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status directly with the supplier or manufacturer before procurement. Ensure that the intended application environment remains within the specified -20°C to +70°C operational limits to maintain the guaranteed ±30 ppm frequency stability. Confirm packaging configuration details such as reel quantity requirements with the distributor.

Crystals Selection Notes

Select this component when a small form factor is required alongside standard 18.432 MHz timing needs. The 12 pF load capacitance specification must align with the host circuit's design parameters to ensure accurate frequency output. Consider the ±30 ppm tolerance against the system's jitter and phase noise requirements.

Crystals Part Context

This part belongs to the 7S series of crystals from TXC Corporation, which focuses on miniaturized surface-mount solutions. It serves as a direct replacement for larger through-hole or older SMD packages in legacy designs requiring the same electrical characteristics but with reduced board space consumption.

Crystals Replacement Considerations

The 7M-18.432MAAE-T is a verified substitute offering identical electrical specifications including 18.432 MHz frequency, 12 pF load capacitance, and ±30 ppm tolerance. Verify mechanical compatibility as the 7M series utilizes a different package outline compared to the 7S series.
