9C25000008

Crystals Overview

The TXC Corporation 9C25000008 is a fundamental frequency quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 25 MHz with a load capacitance of 18 pF and an equivalent series resistance of 30 Ohms. The component provides a frequency tolerance of ±30 ppm across the operating temperature range of -20°C to +70°C. It utilizes the HC-49/US package configuration, featuring a two-terminal leaded structure adapted for SMD mounting.

Crystals Feature Summary

• Provides stable 25 MHz timing signals for digital circuits
• Utilizes HC-49/US package for reliable surface-mount integration
• Maintains frequency stability within specified industrial temperature limits

Crystals Applications

• Microcontroller clock generation
• Communication interface synchronization
• Digital signal processing timing references

Crystals Procurement Notes

Verify manufacturer authenticity through authorized channels to ensure component integrity. Confirm that the specific suffix matches the required electrical parameters and package style. Check datasheets for RoHS compliance status and handling instructions. Validate supply chain documentation against official TXC records before final procurement decisions.

Crystals Selection Notes

Select this model when a 25 MHz reference with 18 pF load capacitance is required. Ensure the PCB layout accommodates the HC-49/US footprint dimensions. Consider the ±30 ppm tolerance against system jitter requirements. Verify that the operating environment stays within the -20°C to +70°C range for guaranteed performance.

Crystals Part Context

This component belongs to the TXC crystal resonator family, serving as a passive frequency control element. It differs from active oscillators by requiring an external circuit to generate a square wave output. The HC-49/US form factor is widely adopted in consumer electronics and industrial equipment for cost-effective timing solutions.

Crystals Replacement Considerations

Cross-reference with other 25 MHz crystals having identical 18 pF load capacitance and HC-49/US packages. Verify that substitute parts meet the same ±30 ppm tolerance and temperature specifications. Ensure mechanical compatibility with existing board layouts.
