7R-26.000MDDB-T

Crystals Overview

The 7R-26.000MDDB-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 6 pF. The component features a tight initial tolerance and stability of ±20 ppm across the operating temperature range of -20°C to +70°C. It utilizes a glass-sealed package structure housed in a compact 4-SMD, no-lead footprint measuring 2.0 mm x 1.6 mm x 0.6 mm. The equivalent series resistance (ESR) is specified at 150 Ohms, ensuring reliable oscillation characteristics within automotive and industrial electronic circuits.

Crystals Feature Summary

• Glass-sealed construction provides enhanced environmental protection and long-term reliability.
• Compact 4-SMD no-lead package facilitates automated surface-mount assembly processes.
• High frequency stability of ±20 ppm ensures precise timing accuracy under varying conditions.

Crystals Applications

• Automotive infotainment and control systems
• Industrial communication modules
• Precision timing circuits requiring stable clock signals

Crystals Procurement Notes

Verify that the specific suffix 'DDB' corresponds to the required glass-sealed variant and 6 pF load capacitance, as standard variants may differ. Confirm the operating temperature range of -20°C to +70°C aligns with the target application's thermal environment. Ensure the 4-SMD no-lead footprint dimensions match the PCB land pattern design to prevent soldering defects during assembly.

Crystals Selection Notes

Select this component when a robust glass-sealed crystal is required for environments demanding higher durability than standard ceramic packages. The ±20 ppm stability is suitable for applications needing tighter frequency control than general-purpose crystals. Consider the 150 Ohm ESR value to ensure compatibility with the oscillator circuit's drive level requirements and startup performance specifications.
