LFXTAL003084B

Overview

LFXTAL003084B is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a nominal frequency of 4.096 MHz. It features a frequency tolerance of ±30ppm and stability of ±50ppm with a load capacitance of 30pF. The component utilizes an HC-49/US package for through-hole mounting, measuring 11.35mm in length and 4.85mm in width. It exhibits an equivalent series resistance (ESR) of 130 Ohms and operates within a temperature range of -10°C to +60°C.

Feature Summary

• Provides precise timing signals via fundamental mode quartz resonance
• Ensures stable oscillation frequencies under specified load conditions
• Supports reliable integration into standard through-hole printed circuit board layouts

Applications

• Microcontroller clock source generation
• Digital logic timing reference circuits
• Communication interface synchronization modules

Procurement Notes

Verify the specific package variant upon ordering, as documentation indicates potential confusion between HC-49/US and HC-49/4H designations for this part number. Confirm that the required frequency tolerance and stability meet the target application's strict timing requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 4.096 MHz reference is required for through-hole designs. Ensure the circuit can accommodate the 130 Ohm ESR and 30pF load capacitance. Consider the limited temperature range if operation outside -10°C to +60°C is necessary.

Part Context

This crystal belongs to the general category of fundamental mode quartz resonators used for frequency control. It serves as a passive timing element essential for synchronizing digital systems. The HC-49 form factor is widely recognized for its durability and ease of manual or automated insertion into electronic assemblies.

Replacement Considerations

The Würth Elektronik part number 830003084B is documented as a parameter-equivalent substitute. Verify mechanical fit and electrical parameters against official datasheets before substitution.
