7R-27.120MAAQ-T

Crystals Overview

The 7R-27.120MAAQ-T is a quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount technology applications. It operates at a fundamental frequency of 27.12 MHz with a load capacitance of 10 pF and an equivalent series resistance of 60 Ohms. The component exhibits a frequency tolerance and stability of ±30 ppm at both 25°C and the operating range of -20°C to +70°C. Housed in a compact 2.0 mm x 1.6 mm SMD package with a height of 0.8 mm, it utilizes a glass seal construction. The device is supplied in reel packaging, facilitating automated assembly processes.

Crystals Feature Summary

• Utilizes glass seal construction for environmental protection
• Supports surface-mount installation via four-pad no-lead design
• Maintains stable frequency performance across specified temperature ranges

Crystals Applications

• Clock signal generation in digital circuits
• Timing references in communication modules
• Frequency control in consumer electronics

Crystals Procurement Notes

Verify the specific ordering suffix against official TXC documentation to ensure correct electrical parameters and packaging configuration. Confirm that the requested variant matches the required load capacitance and frequency tolerance specifications for your circuit design. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards and RoHS compliance requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small footprint is critical due to its 2.0 mm x 1.6 mm dimensions. Ensure the application requires a 10 pF load capacitance and can accommodate a 60 Ohm ESR. Verify that the operating environment stays within the -20°C to +70°C range to maintain the specified ±30 ppm stability. Consider the glass seal type if enhanced moisture resistance is needed compared to ceramic alternatives.

Crystals Part Context

This part belongs to the 7R series of quartz crystals from TXC Corporation, which are characterized by their miniature size and glass-sealed construction. The series is engineered for high-volume surface-mount production lines, offering reliable timing solutions for space-constrained electronic devices. The 7R designation specifically indicates the 2.0 x 1.6 mm package style within the manufacturer's portfolio.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 2.0x1.6 mm dimensions, 10pF load capacitance, and ±30ppm stability. Verify pinout compatibility and mounting pad layout equivalence to ensure seamless integration without PCB redesign.
