7M-20.000MEEI-T

Crystals Overview

The 7M-20.000MEEI-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 high frequency stability of ±10 ppm. The component utilizes a 4-SMD, no-lead package measuring 3.2 mm in length and 2.5 mm in width. Key electrical specifications include a load capacitance of 16 pF and an equivalent series resistance (ESR) of 50 Ohms.

Crystals Feature Summary

• High frequency stability of ±10 ppm ensures precise clock generation
• Compact 4-SMD no-lead surface mount package design
• Fundamental mode quartz crystal construction

Crystals Applications

• Precision digital clock circuits
• Microcontroller system clocks
• Communication interface timing sources

Crystals Procurement Notes

Verify the specific suffix 'EII' against official datasheets to confirm pinout and tolerance parameters. Ensure compatibility with reflow soldering profiles specified for 4-SMD packages. Confirm RoHS compliance status prior to integration into final assemblies.

Crystals Selection Notes

Select this component when strict timing accuracy within ±10 ppm is required. The 16 pF load capacitance must match the oscillator circuit design. Consider the 3.2x2.5 mm footprint constraints during PCB layout planning.

Crystals Part Context

This part belongs to the TXC 7M series of miniature quartz crystals. It serves as a passive frequency control element, distinct from active oscillators. The series is characterized by small form factors suitable for dense electronic layouts.

Crystals Replacement Considerations

The 7M-20.000MEEJ-T is listed as a similar alternative. Verify that its ±10 ppm stability and 16 pF load capacitance match the original requirements before substitution.
