8Q-25.000MDDV-T

Crystals Overview

The 8Q-25.000MDDV-T is a standard quartz crystal oscillator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 25 MHz with a load capacitance of 8 pF. The component features a frequency tolerance and stability of ±20 ppm at 25°C, and ±20 ppm over the operating temperature range of -20°C to +70°C. It utilizes a seam-sealed ceramic package measuring 1.6 mm x 1.2 mm in a four-pad SMD configuration without leads.

Crystals Feature Summary

• Seam-sealed ceramic construction for environmental protection
• Four-pad surface-mount design for compact PCB integration
• High frequency stability within specified industrial temperature ranges

Crystals Applications

• General-purpose timing circuits requiring stable clock signals
• Embedded systems utilizing microcontrollers or processors
• Consumer electronics with space-constrained layouts

Crystals Procurement Notes

Verify that the specific part number matches the required frequency tolerance and temperature range specifications before procurement. Confirm the seam-sealed ceramic package dimensions align with the target PCB footprint. Ensure compatibility with the intended load capacitance requirements of the host circuit design.

Crystals Selection Notes

Select this component when a small form factor is critical for the design. The 1.6x1.2 mm package size supports high-density board layouts. Consider the ±20 ppm stability requirement against the system's timing accuracy needs. Verify that the -20°C to +70°C operating range meets the environmental conditions of the final application.

Crystals Part Context

This component belongs to the TXC 8Q series of surface-mount crystals. It represents a miniaturized solution compared to larger through-hole or standard SMD packages. The series focuses on providing reliable timing sources for modern electronic devices where space optimization is a primary design constraint.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 8 pF load capacitance, and 1.6x1.2 mm package dimensions. Verify equivalent frequency stability ratings across the same temperature range. Check for compatible ESR values and drive level specifications to ensure circuit performance parity.
