LFXTAL035264

Overview

The LFXTAL035264 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 16 MHz with a frequency tolerance and stability of ±50 ppm. The component utilizes a parallel resonant mode and features a load capacitance of 16 pF and an equivalent series resistance (ESR) of 70 Ohms. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. The device employs a ceramic body with a seam-sealed metal lid for hermetic sealing.

Feature Summary

• Hermetically sealed construction using a seam-sealed metal lid over a ceramic body to ensure environmental protection and long-term reliability.
• Compact surface-mount footprint designed for automated assembly processes in space-constrained electronic applications.

Applications

• Clock signal generation in microcontroller systems
• Timing references in communication modules
• Frequency control in consumer electronics

Procurement Notes

Verify the specific packaging configuration, such as tape-and-reel or bulk quantities, against the manufacturer's current documentation before ordering. Confirm that the hermetic seal type aligns with the environmental requirements of the target application. Ensure compatibility with standard reflow soldering profiles specified for this package style.

Selection Notes

Select this component when a 16 MHz reference is required in a small form factor. The ±50 ppm tolerance suits general-purpose timing applications where high precision is not critical. Consider the 16 pF load capacitance requirement to ensure proper circuit oscillation. Evaluate the hermetic sealing benefits if operating in harsh environments compared to non-hermetic alternatives.

Part Context

This part belongs to the CFPX-180 series of quartz crystals from IQD Frequency Products. The series is characterized by its robust hermetic sealing technology, combining a ceramic substrate with a metal lid. This design distinguishes it from standard plastic-packaged crystals by offering superior resistance to moisture and contaminants, suitable for demanding industrial and commercial uses.

Replacement Considerations

Direct replacements must match the 16 MHz frequency, 16 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that substitute components offer comparable ESR values and hermetic sealing characteristics to maintain circuit performance and reliability standards.
