LFXTAL033416

Overview

The LFXTAL033416 is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a fundamental frequency of 6 MHz. It features a load capacitance of 18 pF and a frequency tolerance of ±30 ppm. The component exhibits an equivalent series resistance (ESR) of 60 Ohms and is designed for surface mount technology (SMT) applications. It utilizes the HC49/4HSMX package format, which is a standard industry footprint. The device is supplied in reel packaging, facilitating automated assembly processes.

Feature Summary

• Surface mount design compatible with automated pick-and-place equipment
• Hermetically sealed construction using resistance welding for environmental protection
• Fundamental mode operation providing stable timing reference signals
• Standardized HC49/4HSMX footprint ensuring board layout compatibility

Applications

• General purpose clock generation for microcontroller systems
• Timing references for digital communication interfaces
• Frequency control circuits in consumer electronic devices
• Industrial control system oscillator modules

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging configuration, as the base part number may correspond to bulk or tape options depending on the manufacturer's current nomenclature. Confirm RoHS compliance status through the official datasheet before integration. Ensure the selected variant matches the required ESR and load capacitance specifications for the target circuit design to guarantee oscillation stability.

Selection Notes

Select this component when a 6 MHz fundamental frequency is required for surface mount applications. The 18 pF load capacitance must match the external capacitors specified in the host oscillator circuit design. Consider the 60 Ohm ESR value to ensure it falls within the driving capability limits of the chosen oscillator IC. The HC49/4HSMX package size should be evaluated against available PCB real estate constraints.

Part Context

This component belongs to the IQD LFXTAL series of quartz crystals, which are widely used for frequency control in electronics. The LFXTAL033416 specifically represents a surface mount variant of the traditional HC49/4H through-hole crystal, offering similar electrical performance in a compact form factor suitable for modern printed circuit board assemblies.

Replacement Considerations

Direct substitutes include other manufacturers' 6 MHz SMD crystals in the HC49/4HSMX package with matching 18 pF load capacitance and ±30 ppm tolerance. Verify that alternative components meet the same ESR requirements and physical dimensions to ensure mechanical fit and electrical equivalence without redesigning the oscillator circuit.
