LFXTAL012504BULK

Overview

The LFXTAL012504BULK is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 24 MHz with a frequency tolerance of ±30ppm and stability of ±50ppm. The component features a load capacitance of 16pF and an equivalent series resistance (ESR) of 40 Ohms. It utilizes the HC-49/US package style, measuring 11.30mm in length, 4.70mm in width, and up to 4.50mm in height. Designed for base harmonic operation, it supports a working temperature range of -10°C to +60°C.

Feature Summary

• Provides precise timing signals for clocking circuits and digital systems
• Ensures reliable frequency generation through stable quartz resonance
• Supports surface-mount assembly for automated manufacturing processes

Applications

• Clocking circuits in microprocessors and microcontrollers
• Timing systems for communication interfaces
• Frequency reference sources for digital logic applications

Procurement Notes

Verify that the specific part number matches the required frequency and package dimensions. Confirm that the load capacitance aligns with the host circuit design. Ensure the operating temperature range meets the environmental requirements of the final application. Check for RoHS compliance status if restricted substances are a concern. Validate the supplier source against authorized distributor lists to ensure authenticity.

Selection Notes

Select this component when a 24 MHz fundamental mode crystal is required for surface-mount designs. Consider the 16pF load capacitance requirement for oscillator circuit compatibility. Evaluate the ESR value against the oscillator driver strength limitations. Assess the physical footprint constraints against the available PCB space. Review the temperature stability specifications for the intended operational environment.

Part Context

This component belongs to the HC49/4HSMX series from IQD Frequency Products. It represents a standard surface-mount variant of the traditional HC-49/U through-hole crystal. The bulk packaging indicates availability for high-volume manual or semi-automated placement. It serves as a direct replacement for legacy through-hole crystals where SMT conversion is necessary.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Verify pinout compatibility and electrical parameters before substituting with other manufacturers' components. Ensure any alternative part meets the same frequency tolerance and load capacitance requirements.
