7R-40.000MEEV-T

Crystals Overview

The 7R-40.000MEEV-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 40 MHz with a load capacitance of 8 pF. The component features a tight frequency tolerance of ±10 ppm and a stability of ±10 ppm over the operating temperature range of -20°C to +70°C. Housed in a compact 2.0 mm x 1.6 mm glass-sealed package, it exhibits an equivalent series resistance (ESR) of 80 Ohms. This SMD device utilizes a four-terminal no-lead configuration for reliable circuit integration.

Crystals Feature Summary

• Glass-sealed construction for enhanced environmental protection
• Compact 2.0x1.6 mm surface-mount footprint
• High frequency stability within specified temperature limits

Crystals Applications

• Microcontroller clock sources
• Communication module timing circuits
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix 'V' against official manufacturer documentation to confirm the exact pinout and sealing type. Ensure the design-in process accounts for the 8 pF load capacitance requirement to maintain the specified ±10 ppm accuracy. Cross-reference the 80 Ohm ESR value with the target oscillator circuit parameters to guarantee stable startup conditions.

Crystals Selection Notes

Select this component when a small form factor is required alongside high frequency stability. The glass seal offers superior performance compared to standard ceramic packages in harsh environments. Consider the 80 Ohm ESR when designing the drive level constraints to prevent frequency shifts or aging issues during operation.

Crystals Part Context

This part belongs to the 7R series of quartz crystals from TXC Corporation. The series is characterized by its small physical dimensions and robust glass-sealing technology. It serves as a critical passive component for generating precise clock signals in modern electronic devices where space constraints are significant.

Crystals Replacement Considerations
