7A-27.120MAAE-T

Crystals Overview

The TXC Corporation 7A-27.120MAAE-T is a surface-mount quartz crystal oscillator operating at a nominal frequency of 27.12 MHz. It features a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 50 Ohms. It is housed in a compact 2-SMD, no lead package measuring 0.197 inches in length by 0.126 inches in width.

Crystals Feature Summary

• Surface mount quartz crystal construction for reliable signal generation
• Compact 2-SMD footprint suitable for space-constrained designs
• Standard 12 pF load capacitance for common circuit integration

Crystals Applications

• Consumer electronics requiring 27.12 MHz clock signals
• Portable devices utilizing standard SMD assembly processes
• General-purpose timing circuits within specified temperature ranges

Crystals Procurement Notes

Verify the specific suffix 'AAE' against official datasheets to confirm the -20°C to +70°C operating range and 12 pF load capacitance. Ensure compatibility with standard reflow soldering profiles for 2-SMD packages. Cross-reference part numbers with manufacturer discontinuation notices if sourcing from secondary markets.

Crystals Selection Notes

Select this component when a 27.12 MHz frequency is required for consumer-grade applications. The ±30 ppm tolerance suits general timing needs rather than high-precision synchronization. Consider the -20°C to +70°C range against environmental requirements; industrial or automotive variants may be necessary for wider thermal extremes.

Crystals Part Context

This part belongs to the TXC 7A series of glass-sealed surface-mount crystals. The series is characterized by robust environmental stability and compatibility with automated SMT manufacturing. The 7A designation typically indicates a specific size and sealing technology optimized for cost-effective mass production in consumer hardware.

Crystals Replacement Considerations

The 8Y-27.120MAAE-T and 8Z-27.120MAHQ-T are listed as alternative parts. Verify pinout compatibility and electrical parameters before substitution. Confirm that any replacement maintains the 27.12 MHz frequency and 12 pF load capacitance.
