8Y-27.120MDIQ-T

Crystals Overview

The 8Y-27.120MDIQ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 27.12 MHz with a frequency stability and tolerance of ±20 ppm at both 25°C and across the extended temperature range of -40°C to +85°C. The component features a load capacitance of 10 pF and utilizes a seam seal package construction within a compact 4-SMD, no-lead footprint measuring 2.0 mm in length and 1.6 mm in width. It is RoHS compliant and classified under ECCN EAR99.

Crystals Feature Summary

• Seam seal ceramic package construction for enhanced environmental durability
• Extended industrial operating temperature range from -40°C to +85°C
• High frequency stability of ±20 ppm maintained across full temperature range
• Compact 2.0mm x 1.6mm surface mount form factor

Crystals Applications

• Industrial control systems requiring stable clock references
• Automotive electronics modules
• Consumer devices with strict size constraints
• Communication equipment baseband processing

Crystals Procurement Notes

Verify that the required frequency tolerance of ±20 ppm aligns with system design specifications, as this part offers tighter stability than standard ±30 ppm alternatives. Confirm that the 2.0x1.6 mm package dimensions fit within the allocated PCB real estate, noting it is smaller than the common 3.2x2.5 mm variant. Ensure the seam seal construction meets any specific environmental protection requirements for the target application environment.

Crystals Selection Notes

Select this component when a small form factor is critical alongside high thermal stability. The 2.0x1.6 mm size is significantly more compact than the 3.2x2.5 mm series, making it suitable for dense layouts. The ±20 ppm stability over the -40°C to +85°C range distinguishes it from lower-grade crystals, ensuring reliable performance in varying thermal conditions without requiring additional compensation.

Crystals Part Context

This part belongs to the 8Y series of seam seal crystals from TXC Corporation. Unlike the 7V or 7M series which typically use 3.2x2.5 mm packages, the 8Y series focuses on miniaturization with a 2.0x1.6 mm footprint. It shares the fundamental quartz technology but differs in physical dimensions and potentially internal electrode structures optimized for the smaller case size while maintaining robust electrical characteristics.

Crystals Replacement Considerations

Direct substitutes must match the 2.0x1.6 mm package, 27.12 MHz frequency, 10pF load capacitance, and ±20 ppm stability. Verify that alternative manufacturers offer equivalent seam seal construction if environmental ruggedness is required.
