8Y-27.000MAAJ-T

Crystals Overview

The TXC Corporation 8Y-27.000MAAJ-T is a surface-mount quartz crystal resonator operating at a nominal frequency of 27 MHz. It features an 18 pF load capacitance and a frequency tolerance of ±30 ppm. The component utilizes the compact 2.0 mm x 1.6 mm x 0.5 mm SMD package, designed for high-frequency stability in space-constrained applications.

Crystals Feature Summary

• Extremely small ceramic construction with seam sealing technology
• High precision and high-frequency stability characteristics
• Surface mount design optimized for automated assembly

Crystals Applications

• Portable ISM band communication devices
• RFID readers and tags
• Medical equipment requiring precise timing

Crystals Procurement Notes

Verify the specific manufacturing revision code (e.g., A2) to ensure compliance with updated Equivalent Series Resistance (ESR) specifications. Confirm that the required load capacitance matches the circuit design, as mismatched values can cause frequency deviation. Ensure the application environment falls within the specified operational temperature range for optimal performance.

Crystals Selection Notes

Select this component when a sub-2mm footprint is critical for miniaturization. The 27 MHz frequency is suitable for baseband oscillation in short-range wireless protocols. Consider the ESR limits if driving weak MCU circuits, as lower ESR versions facilitate easier startup in low-power designs.

Crystals Part Context

This part belongs to the 8Y series of SMD Seam Sealing Crystals from TXC Corporation. These units are characterized by their miniature dimensions and robust ceramic packaging, distinguishing them from larger HC-49 or standard 3225 package crystals.

Crystals Replacement Considerations

Direct substitutes include other 2.0x1.6mm 27MHz crystals with matching 18pF load capacitance and ±30ppm tolerance. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
