LFXTAL032542

Overview

The LFXTAL032542 is a quartz crystal resonator manufactured by IQD Frequency Products, designed for precision timing applications. It operates at a nominal frequency of 3.579545 MHz with a frequency tolerance and stability of ±30 ppm. The component utilizes an HC-49/4HSMX package style, featuring radial termination for through-hole mounting. Key electrical parameters include a load capacitance of 18 pF and an equivalent series resistance (ESR) of 300 Ohms. This standard crystal is suitable for integration into electronic circuits requiring stable clock signals.

Feature Summary

• Provides precise frequency generation at 3.579545 MHz
• Features ±30 ppm frequency tolerance and stability
• Utilizes HC-49/4HSMX package for reliable through-hole mounting

Applications

• General-purpose clock signal generation in electronic circuits
• Microcontroller system timing references
• Embedded device oscillator circuits

Procurement Notes

Verify the specific package variant and termination type against design requirements before ordering. Confirm that the 18 pF load capacitance matches the circuit design specifications to ensure accurate frequency operation. Check current availability status as supply levels may fluctuate. Ensure compliance with relevant environmental standards such as RoHS if required for the target application market.

Selection Notes

Select this component when a 3.579545 MHz reference is required with moderate stability needs. The HC-49/4HSMX form factor is appropriate for through-hole PCB layouts. Consider the 300 Ohm ESR value for driver circuit compatibility. Evaluate whether the ±30 ppm stability meets the system's timing accuracy constraints compared to higher-grade alternatives.

Part Context

This part belongs to the IQD Frequency Products quartz crystal lineup, which includes various frequencies and packages. The LFXTAL series typically offers standard industrial components for general electronics. The HC-49/4HSMX designation indicates a specific surface-mount or modified through-hole variant within the broader HC-49 family, differing from traditional axial leaded crystals.

Replacement Considerations

Direct substitutes must match the 3.579545 MHz frequency, 18 pF load capacitance, and HC-49/4HSMX package dimensions. Verify equivalent ESR values and stability ratings to maintain circuit performance. Cross-reference pinout and mounting hole spacing if mechanical fit is critical.
