LFXTAL059648

Overview

The LFXTAL059648 is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 35 Ohms. The component features a frequency tolerance of ±20 ppm and stability of ±30 ppm. It utilizes a 4-SMD, No Lead package configuration suitable for surface mount technology.

Feature Summary

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

Applications

• General purpose clock signal generation
• Microcontroller timing circuits
• Digital communication interfaces

Procurement Notes

Verify the specific package dimensions and terminal availability against the official datasheet prior to integration. Confirm that the 4-SMD no-lead footprint matches the target PCB layout requirements. Ensure the operating temperature range aligns with the intended application environment specifications.

Selection Notes

Select this component when a 40 MHz reference is required with moderate stability. The 18 pF load capacitance must match the oscillator circuit design. Consider the ESR value for drive level compatibility within the host system's oscillator topology.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio. It serves as a passive frequency control element for electronic systems requiring precise timing references. The manufacturer provides comprehensive technical documentation for design-in support.

Replacement Considerations

Cross-reference compatible parts based on identical 40 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package constraints. Verify electrical parameters such as ESR and tolerance before substitution.
