8Z-27.000MAHE-T

Crystals Overview

The 8Z-27.000MAHE-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 27 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 100 Ohms. The component utilizes a 4-SMD, No Lead package configuration with seam seal construction. Frequency stability is rated at ±30 ppm at 25°C and ±30 ppm across the extended temperature range of -40°C to +85°C. This device provides reliable clock signals for digital circuits requiring stable high-frequency references.

Crystals Procurement Notes

Verify the specific ordering suffix against official TXC documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status through authorized distributors as supply levels may fluctuate. Cross-reference the manufacturer part number with internal bill of materials to prevent substitution errors during procurement processes.

Crystals Selection Notes

Select this component when a 27 MHz output with ±30 ppm stability is required for surface-mount designs. Consider the 12 pF load capacitance requirement for circuit matching. Evaluate the 100 Ohm ESR against oscillator driver strength capabilities. Assess the -40°C to +85C operating range against the target application's thermal profile before finalizing the design choice.

Crystals Part Context

This crystal belongs to TXC Corporation's 8Z series of seam-sealed surface-mount crystals. The series is engineered for applications demanding high reliability and compact form factors. The 27 MHz frequency is commonly used in legacy video and communication standards. The 8Z designation indicates specific dimensional and sealing characteristics distinct from other TXC crystal families.

Crystals Replacement Considerations

Direct substitutes include the 8Z-27.000MAAE-T, which shares similar electrical parameters but may differ in temperature range or packaging details. Verify all critical specifications including load capacitance, ESR, and stability before implementing any alternative part numbers to ensure circuit functionality remains intact.
