8Q-26.000MDDY-T

Crystals Overview

The 8Q-26.000MDDY-T is a surface-mount MHz quartz crystal manufactured by TXC Corporation, designed for high-frequency signal generation in compact electronic systems. It operates at a nominal frequency of 26.000 MHz with a tight initial tolerance of ±20 ppm at 25°C and maintains ±20 ppm stability across the industrial temperature range of -20°C to +70°C. The component utilizes a 7 pF load capacitance and features an equivalent series resistance (ESR) of 100 Ohms. Housed in a miniature 4-SMD, No Lead package measuring 1.6 mm x 1.2 mm, it supports seam seal construction for enhanced environmental protection. This device is suitable for applications requiring precise timing within restricted board space constraints.

Crystals Feature Summary

• Seam seal ceramic construction provides robust environmental protection against moisture and contaminants.
• Compact 1.6mm x 1.2mm SMD footprint enables placement in space-constrained mobile and portable designs.
• Tight frequency stability of ±20 ppm ensures reliable clock synchronization across operating temperatures.

Crystals Applications

• Mobile communication devices requiring precise RF carrier frequencies
• Portable consumer electronics with limited PCB real estate
• Industrial control systems needing stable timing references

Crystals Procurement Notes

Verify the specific suffix 'DY' confirms the 7pF load capacitance and 100 Ohm ESR parameters before ordering. Ensure the design accommodates the 1.6x1.2mm package dimensions and seam seal mounting requirements. Confirm that the ±20ppm stability specification meets the system's timing accuracy needs across the -20°C to +70°C operating range. Cross-reference the datasheet for reflow soldering profiles compatible with this specific ceramic package type.

Crystals Selection Notes

Select this component when a small form factor is critical alongside strict frequency stability requirements. The 26 MHz output is standard for certain wireless protocols, while the 7pF load matches common oscillator circuit configurations. Consider the 100 Ohm ESR value to ensure proper drive level management within the host circuit. Compare against larger packages if higher power handling or different temperature ranges are required.

Crystals Part Context

This part belongs to TXC's line of miniature surface-mount crystals, specifically utilizing seam seal technology for durability. It complements larger 3250 or 2016 packages by offering a reduced footprint for ultra-compact applications. The 26 MHz frequency is commonly used in Bluetooth and proprietary wireless interfaces.

Crystals Replacement Considerations

Direct substitutes must match the 1.6x1.2mm package, 26 MHz frequency, 7pF load, and ±20ppm stability. Verify ESR compatibility at 100 Ohms. Check manufacturer-specific reflow profiles for seam seal variants.
