7R-40.000MEEE-T

Crystals Overview

The TXC Corporation 7R-40.000MEEE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 40 MHz. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. The component utilizes a glass seal construction with a four-pad SMD package, measuring 2.0 mm by 1.6 mm. It provides a frequency stability of +/-10 ppm at 25°C and +/-10 ppm across the industrial temperature range of -20°C to 70°C.

Crystals Feature Summary

• Glass-sealed ceramic construction for enhanced environmental durability
• High frequency stability within specified temperature ranges
• Compact surface-mount footprint suitable for space-constrained designs

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration prior to ordering. Confirm that the -20°C to 70°C temperature rating aligns with the target application environment requirements. Ensure the 12 pF load capacitance matches the oscillator circuit design specifications to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a compact, glass-sealed crystal is required for moderate temperature environments. Compare against the 7R-40.000MEEC-T variant if extended temperature range or different load capacitance is needed. Verify package dimensions fit the PCB layout constraints due to the small 2.0x1.6 mm form factor.
