7M-25.000MBBK-T

Crystals Overview

The 7M-25.000MBBK-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for commercial applications. It operates at a nominal frequency of 25 MHz with a load capacitance of 20 pF and a frequency tolerance of ±50 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and supports a maximum drive level of 50 µW. It utilizes a four-terminal SMD package without leads, measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. The device functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides stable oscillation at 25 MHz using a seam seal ceramic package construction
• Designed for surface-mount integration with a compact four-terminal footprint
• Maintains frequency stability within specified limits across the commercial operating temperature range

Crystals Applications

• General-purpose clock signal generation in commercial electronic circuits
• Timing reference sources for microcontrollers and digital logic systems
• Oscillator circuits requiring standard 20 pF load capacitance matching

Crystals Procurement Notes

Verify that the target circuit design accommodates the specific 20 pF load capacitance requirement to ensure accurate frequency operation. Confirm that the available drive level of 50 µW aligns with the oscillator circuit's output power specifications to prevent overdriving the crystal. Ensure the PCB layout supports the 4-SMD no-lead package dimensions for proper soldering and mechanical stability during assembly processes.

Crystals Selection Notes

Select this component when a 25 MHz timing source is required for commercial-grade devices operating between -20°C and +70°C. Choose this part if the application necessitates a 20 pF load capacitance and can tolerate a ±50 ppm frequency tolerance. Consider this model for designs where the 60 Ohm ESR and 50 µW drive level are compatible with the host oscillator circuit constraints.

Crystals Part Context

This component belongs to the 7M series of quartz crystals from TXC Corporation, which are characterized by their seam seal ceramic packaging. The series offers various frequency and tolerance options tailored for commercial electronics. The 7M-25.000MBBK-T specifically addresses the need for a reliable 25 MHz reference in space-constrained surface-mount designs.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 20 pF load capacitance, and 4-SMD no-lead package. Verify that alternative parts support the same -20°C to +70°C operating range and similar electrical parameters like ESR and drive level.
