7V-27.120MDDQ-T

Crystals Overview

The 7V-27.120MDDQ-T is a surface-mount ceramic crystal manufactured by TXC Corporation, operating at a nominal frequency of 27.12 MHz. It features a load capacitance of 10 pF and maintains a frequency stability of ±20 ppm across an operating temperature range of -20°C to +70°C. The component utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm in length and 2.5 mm in width. Designed for base mode operation, it supports SMD/SMT installation styles and is supplied in reel packaging.

Crystals Feature Summary

• Provides stable clock signals via piezoelectric ceramic resonance
• Supports surface-mount integration for automated assembly processes
• Maintains specified frequency tolerance within defined thermal limits

Crystals Applications

• General-purpose digital circuit timing references
• Microcontroller clock source generation
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the exact ±20 ppm stability rating, as variations exist within the 7V series. Ensure compatibility with the target load capacitance of 10 pF during PCB layout design. Confirm RoHS compliance status through current manufacturer documentation prior to final procurement decisions.

Crystals Selection Notes

Select this component when a compact 3.2 x 2.5 mm footprint is required for space-constrained designs. Choose based on the need for ±20 ppm stability rather than the wider ±30 ppm options available in the same series. Consider the -20°C to +70°C temperature range suitability for standard commercial applications requiring reliable ceramic crystal performance.
