8Z-12.288MEHQ-T

Crystals Overview

The 8Z-12.288MEHQ-T is a quartz crystal oscillator manufactured by TXC Corporation, designed for high-reliability applications requiring tight frequency stability. Operating at a fundamental frequency of 12.288 MHz, this component utilizes a seam-sealed package construction to ensure environmental durability and long-term performance consistency. The device is housed in a compact 4-SMD, no-lead surface-mount footprint with dimensions of 2.5 mm x 2.0 mm, facilitating automated assembly and space-constrained board layouts. It is engineered to provide stable clock signals for digital circuits within standard industrial operating temperature ranges.

Crystals Feature Summary

• Seam-sealed package construction provides enhanced protection against moisture and contaminants for improved reliability.
• Compact 4-SMD no-lead surface-mount design supports efficient PCB layout and automated pick-and-place manufacturing processes.

Crystals Applications

• Industrial control systems requiring robust clock sources
• Telecommunications equipment needing stable frequency references
• Automotive electronics demanding high environmental resistance

Crystals Procurement Notes

Verify the specific electrical parameters, such as load capacitance and frequency tolerance, against the official datasheet before integration, as these values are critical for circuit compatibility. Confirm that the seam-sealed package type aligns with the thermal and mechanical requirements of the target application environment. Ensure that the supply chain source provides authentic components to maintain signal integrity and longevity.

Crystals Selection Notes

Select this component when a small form factor is required alongside high environmental resilience due to its sealed construction. Compare it against open-can crystals if superior shock resistance is needed, or against MEMS oscillators if lower phase noise is the primary constraint. Evaluate the 2.5x2.0mm footprint against available PCB real estate and verify that the 12.288 MHz frequency matches the system clock architecture without requiring additional dividers.

Crystals Part Context

This part belongs to the TXC 8Z series of seam-sealed quartz crystals, which are distinguished by their hermetic sealing technology compared to standard epoxy-sealed alternatives. The series targets markets where long-term drift and environmental exposure are critical failure points. It serves as a direct replacement for older through-hole or larger SMD crystals in designs prioritizing durability over cost reduction.
