7R-26.000MEIQ-T

Crystals Overview

The TXC Corporation 7R-26.000MEIQ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a frequency tolerance and stability of ±10 ppm, with a load capacitance of 10 pF. The component utilizes glass sealing technology for enhanced environmental protection and reliability. It is housed in a compact 4-SMD, no-lead package measuring 2.05 mm in length, 1.65 mm in width, and 0.6 mm in height. The equivalent series resistance (ESR) is specified at 150 Ohms, and the recommended drive level is 10 uW.

Crystals Feature Summary

• Utilizes glass sealing technology to ensure long-term stability and environmental robustness.
• Compact surface-mount design suitable for space-constrained electronic applications.
• Provides precise frequency control with ±10 ppm tolerance for accurate timing.

Crystals Applications

• General-purpose digital circuits requiring stable clock signals
• Microcontroller and microprocessor system clocks
• Communication equipment timing references

Crystals Procurement Notes

Verify that the target circuit design supports a 10 pF load capacitance to ensure accurate oscillation frequency. Confirm that the available drive power does not exceed the 10 uW specification to prevent frequency shifts or damage. Ensure the PCB layout accommodates the specific 2.05 mm x 1.65 mm footprint and 0.6 mm height constraints. Check compatibility with the -20°C to +70°C operating temperature range for the intended application environment.

Crystals Selection Notes

Select this component when a small form factor and high reliability are required for 26 MHz timing applications. The glass-sealed construction offers superior performance compared to standard ceramic packages in varying environmental conditions. Consider the 150 Ohm ESR value when designing the oscillator circuit to ensure proper startup and stability. This part is suitable for industrial and commercial applications within its specified temperature range.

Crystals Part Context

This component belongs to the 7R series of SMD glass-sealing quartz crystals from TXC Corporation. The series is designed for applications demanding high stability and durability in compact electronic devices. The 7R series distinguishes itself through the use of glass-sealed resonators, which provide better frequency stability over time and temperature compared to non-sealed alternatives.

Crystals Replacement Considerations

The 7R-26.000MAAJ-T is a parameter-equivalent alternative within the same series, offering similar specifications including 26 MHz frequency and 30 ppm tolerance, though with different load capacitance and ESR values. Verify electrical compatibility before substitution.
