8Q-27.120MAAV-T

Crystals Overview

The 8Q-27.120MAAV-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 27.12 MHz. It features a load capacitance of 8 pF and maintains a frequency stability and tolerance of ±30 ppm across an industrial temperature range of -20°C to +70°C. The component utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm and a maximum height of 0.90 mm. It exhibits an equivalent series resistance (ESR) of 60 Ohms and supports base harmonic operation modes.

Crystals Feature Summary

• Provides precise frequency control for timing circuits through stable quartz resonance
• Supports automated surface-mount assembly processes via standardized SMD packaging
• Ensures reliable performance within specified industrial thermal environments

Crystals Applications

• General-purpose timing references in consumer electronics
• Clock signal generation in communication modules

Crystals Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical parameters such as load capacitance and ESR. Ensure compatibility with PCB footprint requirements and reflow soldering profiles. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production workflows.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental mode crystal is required with an 8 pF load capacitance. Consider the ±30 ppm stability requirement and the -20°C to +70°C operating range. Evaluate the 4-SMD package size constraints against available board space and mounting orientation needs.

Crystals Part Context

This part belongs to the 8Q series of ceramic crystals produced by TXC Corporation. The series focuses on providing cost-effective frequency control solutions for mass-market applications. The 8Q designation indicates specific dimensional and electrical characteristics distinct from other TXC product lines like the 7V or AV series.
