7M-20.000METI-T

Crystals Overview

The 7M-20.000METI-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 16 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency stability of ±10 ppm and supports a wide operating temperature range from -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.80 mm, it utilizes seam seal technology for enhanced reliability.

Crystals Feature Summary

• Seam seal construction provides robust environmental protection and mechanical stability.
• Fundamental mode operation ensures precise frequency generation at 20 MHz.
• Compact 4-SMD no-lead footprint facilitates automated surface-mount assembly.

Crystals Applications

• High-speed digital logic circuits requiring stable clock signals
• Microcontroller and microprocessor system timing references
• Communication equipment interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'METI' against official TXC documentation to confirm the exact stability and packaging specifications. Ensure the target design accommodates the 3.2x2.5 mm SMD footprint and 0.80 mm height constraints. Confirm that the 16 pF load capacitance matches the host circuit requirements for accurate frequency tuning.

Crystals Selection Notes

Select this component when high frequency stability of ±10 ppm is required across industrial temperature ranges. The 60 Ohm ESR value must be compatible with the oscillator circuit's drive level limitations. Consider the seam seal package for applications demanding superior resistance to moisture and contaminants compared to standard epoxy-sealed crystals.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals from TXC Corporation, which are characterized by their small size and high reliability. The series utilizes advanced manufacturing techniques to maintain tight frequency tolerances. The 7M-20.000METI-T specifically targets applications needing a balance between compact form factor and strict performance standards in harsh environments.

Crystals Replacement Considerations

Direct substitutes include the 7V-20.000MAHE-T from TXC Corporation. Cross-manufacturer replacements require verification of identical frequency, load capacitance, ESR, and physical dimensions to ensure circuit compatibility.
