LFXTAL059461

Overview

LFXTAL059461 is a parallel-resonant fundamental quartz crystal from the IQXC-25 series by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance and stability of ±20 ppm. The component features a load capacitance of 7 pF and an equivalent series resistance (ESR) of 90 kOhms. Designed for surface-mount applications, it utilizes a 2-SMD, no-lead package configuration.

Feature Summary

• Fundamental mode parallel resonance operation
• High impedance ESR characteristic suitable for low-power circuits
• Compact 2-terminal SMD footprint

Applications

• Real-time clock circuits
• Microcontroller system oscillators
• Low-frequency timing references

Procurement Notes

Verify the specific packaging variant upon ordering, as sources indicate availability in both bulk and reel configurations. Confirm that the 90 kOhm ESR specification aligns with the oscillator circuit design requirements to ensure proper startup and stability. Cross-reference the IQXC-25 series designation to validate technical parameters against current manufacturer documentation.

Selection Notes

Select this component for applications requiring precise low-frequency timing with minimal power consumption. The high ESR value distinguishes it from standard crystals, making it appropriate for specific CMOS oscillator topologies. Ensure the PCB layout accommodates the small 2-SMD form factor while maintaining signal integrity for the 32.768 kHz signal path.

Part Context

The LFXTAL059461 belongs to the IQXC-25 series, a line of miniature quartz crystals designed for space-constrained electronic devices. This series emphasizes reliability and compactness, catering to modern consumer electronics and industrial control systems where board real estate is limited but timing accuracy remains critical.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 7 pF load capacitance, and similar ESR characteristics. Verify that alternative components support parallel resonance mode and fit the 2-SMD no-lead package dimensions to ensure mechanical compatibility.
