7V-40.000MEIQ-T

Crystals Overview

The TXC Corporation 7V-40.000MEIQ-T is a 40 MHz quartz crystal resonator designed for surface-mount applications. It features a 3.2 mm x 2.5 mm package with glass seal construction and four solder pads. The component operates within a temperature range of -40°C to +85°C, maintaining a frequency stability of ±20 ppm across this range and ±10 ppm at 25°C. It utilizes an 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms.

Crystals Feature Summary

• Glass-sealed ceramic construction for enhanced environmental durability
• High frequency stability with tight tolerance specifications
• Compact surface-mount footprint suitable for space-constrained designs

Crystals Applications

• Precision timing circuits in consumer electronics
• Clock generation for microcontrollers and processors
• Communication equipment requiring stable reference frequencies

Crystals Procurement Notes

Verify the specific suffix 'IQ' against official datasheets to confirm the exact load capacitance and stability ratings, as variations exist within the 7V series. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm RoHS compliance status through current documentation before integration into regulated products.

Crystals Selection Notes

Select this component when a 40 MHz reference is required with high stability over extended industrial temperatures. The glass seal offers superior protection compared to standard epoxy packages. Evaluate the 60 Ohm ESR against oscillator circuit requirements to ensure proper startup conditions and signal integrity.

Crystals Part Context

This part belongs to the 7V series of MHz quartz crystals from TXC Corporation. The series is characterized by its small form factor and robust sealing technology. It serves as a fundamental passive component for generating precise clock signals in modern electronic systems where size and reliability are critical constraints.

Crystals Replacement Considerations

Direct substitutes include the 7V-40.000METV-T and 7V-40.000MAHJ-T, provided their electrical parameters match the design requirements. Verify package dimensions and pin configuration compatibility before substitution.
