LFXTAL026388

Overview

The LFXTAL026388 is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a fundamental frequency of 14.7456 MHz with a frequency tolerance of ±30ppm. The component features a load capacitance of 16pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, No Lead package configuration, measuring approximately 7.00mm in length, 5.00mm in width, and 1.40mm in maximum height. The device supports base harmonic operation modes.

Feature Summary

• Surface-mount design utilizing a compact 4-SMD, No Lead package structure
• Fundamental mode operation providing stable frequency generation
• Standardized load capacitance specification for circuit integration

Applications

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

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, as bulk or reel options may exist within the product line. Confirm that the 14.7456 MHz frequency aligns with the target application's clock requirements. Ensure the 4-SMD footprint matches the PCB land pattern dimensions precisely to avoid assembly defects during placement.

Selection Notes

Select this component when a standard 14.7456 MHz reference is required for SMD assembly processes. The ±30ppm tolerance suits most general digital logic applications where high precision is not critical. Consider the 60 Ohm ESR value for oscillator circuit stability calculations. The physical dimensions fit standard industrial surface-mount reflow profiles.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, which includes various SMD and through-hole resonators. The LFXTAL series typically covers common frequencies used in computing and communication devices. IQD provides these components for industries requiring reliable frequency control solutions with established manufacturing standards.

Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 16pF load capacitance, and 4-SMD package dimensions. Verify equivalent ESR values to maintain oscillator startup reliability. Cross-reference manufacturer-specific pinout compatibility if available.
