LFXTAL059643

Overview

The LFXTAL059643 is a surface-mount quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 26.0 MHz with a frequency tolerance of ±20 ppm and stability of 30 ppm. The device features an 18 pF load capacitance and a drive level of 100 µW. It is housed in a compact 3.2 x 2.5 x 0.8 mm package, suitable for space-constrained designs. The component supports an operating temperature range from -40°C to +85°C and utilizes SMD/SMT termination style.

Feature Summary

• Compact surface-mount design optimized for limited board space
• High frequency stability within specified industrial temperature ranges
• Low power consumption characteristics suitable for portable electronics

Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Communication module oscillator stages

Procurement Notes

Verify the specific suffix designation (e.g., Reel) against the required packaging format for automated assembly lines. Confirm that the 26.0 MHz frequency aligns precisely with the target circuit requirements. Ensure the 18 pF load capacitance matches the host oscillator's specifications to maintain accurate timing performance. Check RoHS compliance status if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a 26 MHz fundamental mode crystal is required in a small footprint. Consider the ±20 ppm tolerance for applications where moderate frequency accuracy suffices. Evaluate the -40°C to +85°C range against the operational environment. Compare ESR and drive level limits with the oscillator IC capabilities to prevent overdriving or startup failures.

Part Context

This part belongs to IQD's standard crystal portfolio, designed for reliable timing in consumer and industrial electronics. It complements other SMD crystals in the LFXTAL series, offering consistent performance across various frequency points. The manufacturer provides extensive support documentation for integration into standard PCB layouts.

Replacement Considerations

Direct substitutes must match the 26.0 MHz frequency, 18 pF load capacitance, and 3.2 x 2.5 mm package dimensions. Verify equivalent electrical parameters such as ESR and drive level before substitution. Cross-reference with other manufacturers' SMD crystal offerings ensuring identical pinout and mechanical constraints.
