LFXTAL055293

Overview

The LFXTAL055293 is a quartz crystal resonator from the CFPX-180 series by IQD Frequency Products. It operates at a fundamental frequency of 14.7456 MHz with a frequency tolerance of ±20 ppm at 25°C. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 120 Ohms maximum. It utilizes a 4-SMD, No Lead surface-mount package, designed for automated assembly processes in electronic circuits requiring precise timing references.

Feature Summary

• Fundamental mode quartz crystal operation
• Surface-mount compatible 4-SMD no-lead package
• Standard 18 pF load capacitance specification

Applications

• General-purpose digital clock generation
• Microcontroller system timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix or bulk/reel packaging designation against the manufacturer's current documentation to ensure compatibility with automated placement equipment. Confirm that the 14.7456 MHz frequency aligns with the target circuit's oscillator design requirements before finalizing procurement orders.

Selection Notes

Select this component when a standard 14.7456 MHz timing source is required for surface-mount designs. The 18 pF load capacitance must match the oscillator circuit's external capacitor values to achieve the specified ±20 ppm accuracy. Ensure the PCB footprint corresponds to the 4-SMD no-lead dimensions provided in the official mechanical drawing.

Part Context

This part belongs to the CFPX-180 series of quartz crystals manufactured by IQD Frequency Products. The series offers various frequencies and package options tailored for consumer and industrial electronics. As a fundamental mode crystal, it provides stable oscillation without the need for internal active components found in oscillator modules.

Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead form factor. Verify that alternative manufacturers' parts meet the same ±20 ppm tolerance and ESR specifications to maintain circuit performance integrity.
