7R-26.000MEEC-T

Crystals Overview

The TXC Corporation 7R-26.000MEEC-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 150 Ohms. The component offers high precision with a frequency tolerance and stability of ±10 ppm at both 25°C and the -20°C to +70°C range. Housed in a compact 4-SMD, No Lead package measuring 2.05 mm x 1.65 mm with a height of 0.6 mm, it utilizes glass seal technology for enhanced reliability.

Crystals Feature Summary

• Utilizes glass seal technology for robust environmental protection
• Provides precise timing with ±10 ppm frequency stability
• Designed for compact surface-mount applications

Crystals Applications

• High-frequency digital signal processing circuits

Crystals Procurement Notes

Verify that the specific ordering suffix matches the required tolerance and packaging configuration. Confirm that the receiving circuit design supports the specified 9 pF load capacitance to ensure accurate frequency operation. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions correctly for reliable soldering.

Crystals Selection Notes

Select this component when a small form factor is critical alongside high frequency stability requirements. The 150 Ohm ESR value should be compatible with the oscillator circuit's drive level specifications. Consider the -20°C to +70°C operating temperature range against the application's environmental conditions.

Crystals Part Context

This part belongs to the 7R series of SMD glass seal quartz crystals from TXC Corporation. These components are engineered for applications demanding superior frequency stability and durability in space-constrained designs. The series represents a balance between performance and miniaturization for modern electronic systems.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 9 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that alternative parts maintain the ±10 ppm stability and similar ESR characteristics to ensure circuit compatibility without redesign.
