7R-25.000MDDB-T

Crystals Overview

The 7R-25.000MDDB-T is a standard quartz crystal manufactured by TXC Corporation, operating at a nominal frequency of 25 MHz. It features a fundamental oscillation mode with a load capacitance of 6 pF and an equivalent series resistance (ESR) of 150 Ohms. The component utilizes a glass-sealed ceramic package in a 4-SMD, no-lead configuration measuring 2.0 mm x 1.6 mm with a maximum height of 0.60 mm. Frequency stability is specified at ±20 ppm relative to 25°C and across the industrial temperature range of -20°C to +70°C.

Crystals Feature Summary

• Glass-sealed ceramic construction for enhanced environmental durability
• Compact 2.0x1.6 mm surface-mount footprint
• Fundamental mode operation with low ESR characteristics

Crystals Applications

• Industrial control systems requiring stable timing references
• Embedded microcontroller clock sources
• Consumer electronics with space-constrained PCB layouts

Crystals Procurement Notes

Verify the specific ordering suffix against the official TXC datasheet to ensure correct tolerance and packaging specifications. Confirm that the required frequency stability meets the system design constraints for the intended operating temperature range. Check current availability status through authorized distributors as supply levels may fluctuate.

Crystals Selection Notes

Select this component when a compact, glass-sealed quartz crystal is required for 25 MHz applications. Ensure the circuit design supports a 6 pF load capacitance to maintain accurate frequency output. Consider the ±20 ppm stability requirement against the operational environment's thermal conditions.

Crystals Part Context

This part belongs to the TXC standard crystal lineup, characterized by its small form factor and robust sealing technology. It serves as a critical timing element in various electronic circuits where size and reliability are prioritized over ultra-high precision stability.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 6 pF load capacitance, 150 Ohm ESR, and 2.0x1.6 mm package dimensions. Verify compatibility with existing PCB footprints and circuit loading requirements before implementation.
