LFXTAL003334

Overview

The LFXTAL003334 is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a fundamental frequency of 7.3728 MHz. It features a load capacitance of 16 pF and an equivalent series resistance (ESR) of 60 Ohms. The component exhibits a frequency tolerance of ±30 ppm and stability of ±50 ppm. Designed for surface-mount applications, it utilizes the HC-49/4H SMX package configuration with two pins. The device supports a minimum operating temperature of -10°C.

Feature Summary

• Fundamental mode operation at 7.3728 MHz
• Surface-mount HC-49/4H SMX package design
• Low equivalent series resistance of 60 Ohms

Applications

• Clock signal generation in digital circuits
• Microcontroller oscillator inputs
• Communication interface timing references

Procurement Notes

Verify the specific packaging variant required for production, as the LFXTAL003334 designation may correspond to tape-and-reel or cut-tape configurations depending on distributor inventory. Confirm that the HC-49/4H SMX footprint matches the target PCB layout. Ensure the ±30 ppm tolerance meets the system's clock accuracy requirements before finalizing the bill of materials.

Selection Notes

Select this component when a standard 7.3728 MHz reference is needed for surface-mount assembly. The 16 pF load capacitance must align with the host circuit's external capacitor values to maintain frequency accuracy. Consider the -10°C minimum operating temperature limit against the environmental conditions of the intended application environment.

Part Context

This part belongs to the IQD Frequency Products crystal family, which provides various frequency control solutions. The LFXTAL series typically includes through-hole and surface-mount options. The HC-49/4H SMX form factor offers a compact alternative to traditional axial leaded crystals while maintaining robust performance for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 7.3728 MHz SMD crystals with matching 16 pF load capacitance and similar ESR values. Verify pin compatibility and physical dimensions when cross-referencing with competing manufacturers' offerings to ensure seamless integration into existing designs.
