LFXTAL003004BULK

Overview

The LFXTAL003004BULK is a quartz crystal manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a standard frequency of 32.768 kHz with a load capacitance of 12.5 pF. The component features a tolerance of ±20 ppm and utilizes a 4-SOJ package with a 2.29 mm lead pitch. It supports through-hole or surface-mount installation styles depending on the specific variant configuration.

Feature Summary

• Provides precise timing reference at 32.768 kHz for digital circuits
• Utilizes compact 4-SOJ surface-mount package design
• Maintains frequency stability within ±20 ppm tolerance

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system clock generation
• Low-frequency timing references in embedded systems

Procurement Notes

Verify the exact package dimensions and pin configuration against the official datasheet before integration. Confirm that the selected variant matches the required load capacitance and frequency tolerance specifications for the target application circuit to ensure proper oscillator startup and stability.

Selection Notes

Select this component when a low-frequency, high-stability timing source is required for space-constrained designs. The 4-SOJ form factor offers a balance between mechanical robustness and small footprint compared to larger through-hole alternatives, suitable for automated assembly processes.

Part Context

This part belongs to the general quartz crystal category from IQD Frequency Products. It serves as a fundamental passive timing element, distinct from active oscillators like TCXOs or VCXOs which include internal amplification circuitry. It relies on external oscillator circuits for signal generation.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 4-SOJ package outline. Verify equivalent electrical parameters such as ESR and drive level sensitivity to ensure compatibility with the existing oscillator circuit design.
