LFXTAL059526

Overview

The LFXTAL059526 is a quartz crystal manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a fundamental frequency of 14.31818 MHz with a load capacitance of 18 pF. The component features a 4-SMD, no-lead package configuration, specifically sized at 3.20 mm in length and 2.50 mm in width. It exhibits a frequency tolerance of ±30 ppm and supports an operating temperature range from -40°C to +85°C. The equivalent series resistance (ESR) is specified at 70 Ohms, ensuring stable performance within standard electronic circuits requiring precise timing references.

Feature Summary

• Surface-mount design utilizing a compact 4-SMD no-lead ceramic package
• Fundamental mode operation providing stable timing signals
• Extended industrial temperature range capability for diverse environments

Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• General-purpose digital logic synchronization

Procurement Notes

Verify the specific package variant and tolerance grade against the official IQD datasheet before integration. Confirm that the 18 pF load capacitance matches the target circuit design requirements. Ensure compatibility with standard SMT reflow processes for the 4-SMD form factor. Cross-reference the ESR value with oscillator amplifier specifications to guarantee reliable startup conditions.

Selection Notes

Select this component when a 14.31818 MHz reference is required in a low-profile surface-mount format. The 18 pF load capacitance suits circuits designed for this specific capacitive loading. Consider the ±30 ppm stability for applications not requiring high-precision oscillators. The wide temperature range makes it suitable for industrial or automotive-grade designs where environmental robustness is necessary.

Part Context

This part belongs to the IQD Frequency Products portfolio of passive quartz components. It serves as a discrete resonator element rather than an active oscillator. The 4-SMD package type aligns with industry-standard footprints for space-constrained PCB layouts. It complements IQD's broader range of HC-49 and larger SMD crystals by offering a smaller footprint solution.

Replacement Considerations

Direct substitutes include other 14.31818 MHz crystals with identical 18 pF load capacitance and 4-SMD dimensions. Verify ESR limits and temperature ranges when evaluating alternative manufacturers. Ensure the replacement maintains the fundamental mode of operation to prevent harmonic interference.
