7V-25.000MDDE-T

Crystals Overview

The 7V-25.000MDDE-T is a fundamental mode quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 25 MHz with a frequency tolerance and stability of ±20 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm with a maximum height of 0.90 mm. The device supports operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental resonance mode quartz crystal construction
• Compact 4-SMD surface-mount footprint
• High frequency stability specification

Crystals Applications

• General-purpose clock signal generation
• Microcontroller timing circuits
• Digital communication interfaces

Crystals Procurement Notes

Verify the specific operating temperature range (-20°C to +70°C) against application requirements, as it differs from standard industrial ranges. Confirm that the 12 pF load capacitance matches the host circuit's design specifications to ensure accurate frequency performance. Ensure the 60 Ohm ESR is compatible with the oscillator circuit's drive level constraints.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal with ±20 ppm stability is required in a small SMD form factor. Consider the limited temperature range of -20°C to +70°C; if wider thermal coverage is needed, alternative models such as those rated for -40°C to +85°C should be evaluated. Verify compatibility with the target PCB layout dimensions of 3.2 mm x 2.5 mm.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. The series offers various frequency options in a standardized 4-SMD package. The 7V-25.000MDDE-T specifically targets applications requiring precise timing at 25 MHz with moderate stability requirements in consumer or industrial electronics.

Crystals Replacement Considerations

Direct substitutes include the 7V-25.000MAHE-T, which shares the same package and frequency but has a wider temperature range (-40°C to +85°C). Other potential replacements may exist within the same manufacturer's portfolio with adjusted temperature ratings.
