LFXTAL027298BULK

Overview

The LFXTAL027298BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 4.0000 MHz with a frequency tolerance of ±30 ppm and stability of ±50 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, equivalent series resistance (ESR) of 300 Ohms, and a drive level of 500 uW. The device is rated for an operating temperature range from -20°C to +70°C.

Feature Summary

• Fundamental resonance operation at 4.0000 MHz
• HC-49/4HSMX through-hole package configuration
• Standard commercial-grade temperature performance

Applications

• General-purpose clock generation circuits
• Microcontroller oscillator inputs
• Consumer electronics timing references

Procurement Notes

Verify the specific suffix 'BULK' against manufacturer documentation to confirm packaging format, as datasheets may list reel options. Confirm RoHS compliance status directly with IQD Frequency Products or authorized distributors, as regulatory details are listed as variable in source data. Ensure the ordering quantity matches the bulk packaging requirements specified in the official product specifications.

Selection Notes

Select this component when a standard 4 MHz reference is required for through-hole PCB designs. The HC-49/4HSMX form factor offers robust mechanical stability compared to surface-mount alternatives. Verify that the circuit's drive level remains within the 500 uW limit to prevent frequency drift or crystal damage during operation.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals. It is distinct from the LFXTAL027298B variant which shares similar electrical characteristics but may differ in packaging or specific manufacturing revisions. The component serves as a passive frequency control element within the broader IQD portfolio of timing solutions.

Replacement Considerations

Cross-reference with LFXTAL027298B if bulk packaging availability is restricted. Verify pin compatibility and electrical equivalence before substituting with other HC-49/4H series crystals from different manufacturers.
