7R-27.000MDDY-T

Crystals Overview

The 7R-27.000MDDY-T is a 27 MHz quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates within a frequency tolerance of ±20 ppm at 25°C and maintains stability across a temperature range of -20°C to +70°C with the same ±20 ppm specification. The component features a load capacitance of 7 pF and utilizes a glass-seal technology housed in a compact 2.0 mm x 1.6 mm package. This SMD device is supplied in tape and reel format, suitable for automated assembly processes.

Crystals Feature Summary

• Utilizes glass-seal technology for enhanced environmental stability
• Compact 2.0x1.6 mm surface-mount footprint
• Maintains consistent frequency tolerance across specified temperature ranges

Crystals Applications

• Consumer electronics requiring precise timing signals
• Communication devices operating at 27 MHz
• Automotive infotainment systems compatible with standard crystal interfaces

Crystals Procurement Notes

Verify the specific suffix requirements against your design specifications to ensure compatibility with load capacitance and temperature ratings. Confirm that the glass-seal construction meets the environmental durability standards required for your target application environment. Cross-reference the package dimensions with your PCB footprint library to guarantee accurate placement during assembly.

Crystals Selection Notes

Select this component when a small form factor is critical for space-constrained designs. The 7 pF load capacitance requires matching oscillator circuit parameters to ensure stable operation. Consider the -20°C to +70°C operating range to verify suitability for the intended thermal environment without requiring additional heating or cooling measures.

Crystals Part Context

This part belongs to the 7R series of crystals from TXC Corporation, characterized by its miniature 2.0x1.6 mm size. It differs from larger packages like the 3.2x2.5 mm variants by offering reduced board area consumption while maintaining standard 27 MHz performance metrics for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 2.0x1.6 mm dimensions and 7 pF load capacitance. Verify equivalent frequency stability and temperature coefficients before swapping manufacturers to maintain circuit integrity.
