LFXTAL055474

Overview

The LFXTAL055474 is a quartz crystal resonator from the CFPX-180 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a load capacitance of 16 pF. The component features a frequency tolerance and stability of ±50 ppm. It utilizes a 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. Equivalent series resistance (ESR) is specified at 50 Ohms.

Feature Summary

• Provides stable 25 MHz timing signals for digital circuits
• Designed for surface mount assembly processes
• Offers consistent frequency performance within specified tolerances

Applications

• General purpose digital clock generation
• Microcontroller system oscillators
• Communication interface timing

Procurement Notes

Verify the specific package variant and manufacturing date code upon ordering. Confirm that the 16 pF load capacitance matches the target circuit design requirements. Ensure compatibility with standard reflow soldering profiles for SMD components. Check for any recent part number revisions or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 25 MHz reference signal is required in a compact surface mount footprint. The ±50 ppm tolerance suits general commercial applications where high precision is not critical. Consider the 16 pF load capacitance requirement to ensure proper oscillator circuit tuning. Evaluate thermal stability needs against the standard operating range defined in the datasheet.

Part Context

This crystal belongs to the CFPX-180 series, representing IQD's portfolio of miniature surface mount quartz resonators. These components are engineered for automated pick-and-place assembly, supporting modern electronics manufacturing trends. The series provides a balance of size reduction and electrical performance for space-constrained designs.

Replacement Considerations

Cross-reference with other 25 MHz crystals in the 3.2x2.5mm SMD package having 16pF load capacitance and similar ESR values. Verify pinout compatibility if substituting with different manufacturers' equivalents.
