7M-20.000MEIV-T

Crystals Overview

The 7M-20.000MEIV-T is a surface-mount MHz quartz crystal manufactured by TXC Corporation. It operates at a fundamental frequency of 20 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 50 Ohms. The component provides a frequency stability of ±10 ppm and is housed in a compact 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm.

Crystals Feature Summary

• Provides high frequency stability of ±10 ppm for precision timing applications
• Utilizes a low-profile surface mount package suitable for space-constrained designs
• Operates on fundamental mode resonance

Crystals Applications

• Precision clock generation in digital systems
• Timing reference for microprocessors and microcontrollers
• Communication interface synchronization circuits

Crystals Procurement Notes

Verify the specific suffix MEIV against the manufacturer's official part number guide to ensure correct tolerance and packaging specifications. Confirm that the 8 pF load capacitance matches the target circuit design requirements. Check RoHS compliance status and moisture sensitivity level prior to integration into the assembly process.

Crystals Selection Notes

Select this component when a tight frequency tolerance of ±10 ppm is required for a 20 MHz application. Ensure the PCB layout supports the 3.2mm x 2.5mm footprint. Verify that the system can accommodate the 8 pF load capacitance requirement to maintain accurate oscillation frequency.

Crystals Part Context

This part belongs to the 7M series of MHz crystals from TXC Corporation. The series offers various frequency options and stability grades in standard SMD packages. This specific model targets applications requiring tighter stability than standard commercial grade crystals while maintaining a small form factor.

Crystals Replacement Considerations

Direct substitutes include the 7V-20.000MAHE-T and 7V-20.000MAAE-T from TXC Corporation. Cross-manufacturer replacements must match the 20 MHz frequency, 8 pF load capacitance, 50 Ohm ESR, and 3.2x2.5 mm package dimensions.
