603-25-203

Crystals Overview

The Fox Electronics 603-25-203 is a surface-mount ceramic crystal resonator operating at a fundamental frequency of 25.0000 MHz. It utilizes a standard SMD package with a maximum seated height of 0.80 mm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 90 Ohms. Frequency tolerance and stability are specified at ±50 ppm. The device is lead-free and RoHS compliant, suitable for general-purpose clock applications in consumer electronics where moderate precision is required.

Crystals Feature Summary

• Surface-mount ceramic construction for reliable PCB integration
• Fundamental oscillation mode at 25 MHz
• Lead-free and RoHS compliant manufacturing

Crystals Applications

• General-purpose microcontroller clock sources
• Consumer electronic timing circuits
• Basic communication interface synchronization

Crystals Procurement Notes

Verify the specific order code against the manufacturer's current catalog to ensure availability of the exact 10pF load capacitance variant. Confirm that the ±50 ppm tolerance aligns with system requirements, as tighter tolerances may require different part numbers. Check for any recent packaging or suffix updates that might affect handling procedures.

Crystals Selection Notes

Select this component when moderate frequency accuracy is sufficient for the application. The 90 Ohm ESR requires adequate oscillator gain margin during circuit design. Ensure the PCB layout accounts for the 10pF load capacitance requirement to maintain accurate frequency output. This part is suitable for non-critical timing applications.

Crystals Part Context

This part belongs to Fox Electronics' standard SMD crystal lineup, offering a balance of cost and performance for mass-produced devices. It serves as a basic timing reference for systems not requiring high-stability industrial-grade specifications. The 25 MHz frequency is a common standard for digital logic and serial communication interfaces.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 10pF load capacitance, and 90 Ohm ESR. Verify package dimensions and pin compatibility before swapping. Alternative parts from other manufacturers should be evaluated for similar ESR characteristics to ensure successful oscillation.
