7V-20.000MEEI-T

Crystals Overview

The 7V-20.000MEEI-T is a MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 16 pF and an equivalent series resistance of 60 Ohms. The component features a glass-sealed package in a 4-SMD, no-lead configuration measuring 3.2 mm x 2.5 mm. It offers high frequency stability of ±10 ppm at 25°C and ±20 ppm over the operating temperature range of -40°C to 85°C.

Crystals Feature Summary

• Glass-sealed construction for enhanced environmental protection
• High frequency stability with tight tolerance specifications
• Compact surface-mount footprint suitable for automated assembly

Crystals Applications

• Precision timing circuits requiring stable clock references
• Microprocessor and microcontroller system clocks
• Communication equipment signal generation

Crystals Procurement Notes

Verify the specific suffix 'EIE' against official datasheets to confirm pinout and electrical characteristics. Ensure compatibility with reflow soldering profiles specified for glass-sealed crystals. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Crystals Selection Notes

Select this component when strict frequency stability within ±10 ppm is required alongside robust environmental sealing. The 16 pF load capacitance must match the oscillator circuit design. Consider the 3.2x2.5 mm package size constraints for PCB layout optimization compared to larger standard crystals.

Crystals Part Context

This part belongs to the 7V series of MHz quartz crystals from TXC Corporation. These components utilize glass-seal technology to provide superior hermeticity compared to standard epoxy-sealed alternatives. The series is engineered for applications demanding long-term reliability and precise frequency control in varying thermal conditions.
